Session Expire

moyphus — Fri, 20 Nov 2009 06:04:58 GMT

While Session Expire, i need to Call One Method... Normally when i click Logout, it will calls one method, the user status also set to logged out, then the session will also expire,.,.,But in this case, suppose the user directly closing the window means, after sometime the session will automatically expire, at that time i have to do changes in database(i.e.Updating the status for that user)...

Thanks in advance, Seetharaman.G

Works within <% %> but not within <%! %>. How can I fix this?

rickprospers — Thu, 19 Nov 2009 15:28:02 GMT

JSP Newbie:

I have a piece of code that works perfectly within the <% %> brackets but I need it to work within the <%! %> brackets.

Here is the code:
------------------------

com.newatlanta.cfc.CFCProxy myCFC = new com.newatlanta.cfc.CFCProxy("xmpp", request, response);

                

                    String jsonMsgData = "A test message";

                    Object[] myArgs = {jsonMsgData};

                

                    java.util.Map map = (java.util.Map)myCFC.invoke("OnAvailabilityChange", myArgs);

-------------------------

I am working with XMPP / Jabber using Smack and I need for this piece of code to be triggered when there is a change in user presence. I already have the trigger code working within the <%! %> brackets and just need to plug this piece in it to be executed. Right now, what I have the trigger code doing is sending me an IM of the user presence. I want to replace the "IM message code" with the above code to be executed.

Obviously the code above is some sort of servlet and I know it works for sure -BUT ONLY- within the <% %> brackets as mentioned previously. Is there a way I can call that piece of code a as a function like doCFCProxy(arg1, arg2...); into the trigger code (that is surrpunded by <%! %>)?

Hello and Thank you in advance for any assistance.

System info:

Netbeans,MySQL,glassfish

The Purpose of this post is:

have someone look at the excel file (subscribe_app_notes2)at :

http://cid-b5cb457363230793.skydrive...se.aspx/Public

The functionality of this code is:

I have the whole package I am creating (pseudo code) stated there along with 3 questions I am presently trying to figure out.

My question is:

One: I am using MySQL and the tutorial I am studying uses Oracle so I need to resolve the resource tag?

Two: My web.xml is different from the one presented in the tutorial. Could someone point out what needs to be added or changed to get it to work with my project?

Three: One of my classes (TopLinkSubscriberDAO.java) is using imports related to Oracle. I am exploring oracle to resolve this. Is anyone able to explain how to resolve errors in this class?

The errors related to this code are:

File Search in jsp

Pranesh_Ashrit — Mon, 16 Nov 2009 05:07:48 GMT

I have written a code to search a file in a given directory. This runs fine on console. But the same code when i run in jsp does not work as expected.

        if(target != null && target.isDirectory())

        {

            for(File f:target.listFiles())

            {

                if(f.isFile())

                {

                    p = Pattern.compile(fileName);

                    m = p.matcher(f.getName());

                    if(m.find())

                        System.out.println("File Found:  "+f.getAbsolutePath());

 else

                        System.out.println("File not found: "+fileName);

                }

                else

                    search(f,fileName);

            }

        }

i have used jsp declaration tag embedding the function which does the above task.

Please guide me to search a file in a given directory using jsp.

The code i have tried in jsp is something like this:

<%!

public static String search(String fileName, String target)

                {

}



%>





<%

List showFiles = search(....);



%>

HttpServlet error

dsmush — Sat, 14 Nov 2009 19:25:38 GMT

Hi,

I'm doing an assignment for University that requires us to make a servlet. I haven't been able to start it yet as I am having trouble compiling the java files. I started of in Linux but could not get Tomcat working so I've resorted to Windows XP. I now have Tomcat installed which is a step in the right direction but there are still problems... I have made a test file to see if it is all working (just a simple Hello World Java servlet). I then go to the Windows command prompt and try to compile it using javac helloWorld.java and 7 errors get spit out into the prompt window. I have Java EE installed but the errors look like it cant find the Java directory. Anyone mind helping me out? because I cant get on with my assignment.

Thank you

Genealogy stuff

dj_dan23 — Fri, 13 Nov 2009 15:34:24 GMT

Hi! All

I would like to have a way to do my application using a simple way.

I have a genealogy site, since a long time ago. I have near 10,000
pages (10,000 names) on a free hoster. Everything works fine. But I'd like to
do the conversion from my FTW (Familky tree maker) to html page ,myself. I've use
VB6 (Visula Basic 6) to do the conversion of all the pages, including all the
html code on each page to link to other page. Like ,click on the father's name
or the childre's name and it load the html page of this INDIVIDUAL.

First : I know very well VB6 , moderate in HTML , poor in Javascript.

Second : I have 10,000 pages (One for each individual), so is there a way
to only have a template page (on the server side = my hoster) and
a few text file (.txt) to pick up the data. Cause there are only 40-50
string data to put on each page but a lot of html code to make a
good looking page. So having a template html page that we can just
add at the right place ,the data of this individual then send it
would be much smaller. So instead of a lot of pages there will be only a few.

Third : I'd like to place on the viewable page, 3 cascading "selection list".
The first one will be populated with the letter from A to Z , from the
HTML code. The second list would have all the name of the family , like
Smith, Johnson, rimes etc , ordered. I already have a text file of
those names. And the third list , will have all the first name like Daniel
Steve, Leann, ordered too, and I also have this ordered text file.
So in a few click , we will be able to go to another individual.

Have try a lot of things but never been able to do it.
I like to keep the text file for data, as it's very easy
to change using VB6 and easy to read, too.

As written before, it must be easy to understand.
I don't mind giving a small donation to have it, cause I really
try hard to do it without been able to do it working.
And it could be useful to other, too.

Thanks at advance.

Hey guys,
I've very new to JSP, Java, and Netbeans and I'm having an issue... So I've got an ArrayList of User objects and I'm trying to iterate over the list in a JSP page to display the info. I've included the JSTL 1.1 jstl and standard libraries. Here is my code for the JSP:

romilc — Thu, 12 Nov 2009 04:17:12 GMT

I am developing a Tic-Tac-Toe game which can be played between two players who are on two different machines.
When the first player comes to the Welcome page he will redirected to a Waiting Page when he clicks on the 'Start' button.

So how can i redirect the first player to the Game page after the second player is available for the game.
And if i want to manage multiple instances of my game how can i do that//
I am using JSP, javascript and MySQL for developing my project, and I am new to all these tools, but i would still like to carry on with all these only

Input to servlet

glendavis — Tue, 10 Nov 2009 11:02:44 GMT

I wrote some html code that lets the user choose an input from a drop down menu then it is passed into a servlet and that creates an HTML document with the output. How does the servlet get the input from the user. In other words, what code do i have to write in the servlet .java file to get the input from the html?

Servlet to JSP

Display image on jsp page

shuchi.vishnoi — Tue, 10 Nov 2009 09:29:41 GMT

I have to display image on jsp page with some text output. This image is already saved at a location parallel to web-inf and is generated dynamically using a servlet. I have used img tag html to display the image. Other outputs are taking their values from database.
First problem is that image will be taking time to display in comparision of other outputs from database. I have to refresh the page to get image on my page.
Second is that if I save image in a folder parallel to web-inf in my project then it will not be displaying the image.
Can I use any jsp functionality to display image with other outputs from database. I have used "include". but it shows only that image and not other outputs.

Table locked and session was invalidated

tarek.mostafa — Mon, 09 Nov 2009 11:41:22 GMT

I have a simple question, I developed a java application, which runs on Oracle application server and Oracle database. This application depends on multiple JSPs on which multiple users can access a single JSP in the same time, some problems occurs due to the excessive usage of this application and I have some questions about them:

1. Is there any danger or disadvantages in connecting to the database using the jdbc directly from the JSP ?!!

2. An error occurs almost once a week (most probably at the point of time when an excessive usage happens). This error stops the users from submitting or accessing the some JSPs. I ran the following query on the DB to find any locked items:

SELECT o.owner, o.object_name, o.object_type, o.last_ddl_time, o.status,l.session_id, l.oracle_username, l.locked_mode
FROM dba_objects o, gv$locked_object l
WHERE o.object_id = l.object_id;

I found that the table I use to select from in the halted JSPs is a result of this query.

In order to solve this problem temporarily, i use the sql developer to add a record to this table and commit, i find that the problem is solved and the halted jsps involved are running.

These are the exceptions that appears in the log files of the application server right after I press commit:

a.java.lang.IllegalStateException: Session was invalidated (all the time)
b.java.sql.SQLException: Closed Connection (some times)

I do not know exactly where to start debugging, since i use synchronization in all of my code. Also I made sure that each user accessing the same JSP has a separate connection.

Thanks in advance

Layout template

ibanez270dx — Thu, 05 Nov 2009 04:18:39 GMT

Hey guys,
I'm currently learning JSP and Java using Netbeans, and I was wondering if there was an easy way to create a web template layout. For example, using a single header, footer, and navigation bar for all pages. In Ruby on Rails, there is a "layouts" view, which you can define an .rhtml page and simply put the yield tag, <%= yield %> . Once this is done, all of the views you create will simply append the layout where the yield tag is. Is there something similar to this that I can use for a Java Web App?

Thanks,

send a function in a JSON through java

santiagozky — Tue, 03 Nov 2009 18:55:31 GMT

Hello everyone,

first of all, I dont know if this should be in the java or the jsp forum. I put it here since is a web related question.

I am making a report module for a web page using java. For this I will use a jquery plugin called datatables (I'm not sure if it's allowed to link to it). The point is that I need to generate a json string dynamically in order to get my reports.

The problem is that along with my data I will also have to send some anonymous functions in the json. I have used some libraries to convert java objects to a json string but nothing on how to send a function.

The jsons will look something like this:

{

"aoColumns": [        

        { "sTitle": "Column 1" },

        { "sTitle": "Column2" },

        { "sTitle": "Column3" },

        { "sTitle": "Column centered", 

                     "sClass": "center" },

        {"sTitle": "Column rendered",

                  "sClass": "center",

          "fnRender": function(obj) {

                var sReturn = obj.aData[ obj.iDataColumn ];                if ( sReturn == "A" ) {

                        sReturn = "A";

                }

                return sReturn;

                }

        }

        ]

}

I know I can generate it manually as a string, but that seems quite complex and I would like to keep that as a las resort.

Anyone knows a library that can generate javascript functions from java?

Thank you for any help you can provide me. This place looks quite nice btw

how to increase users in tomcat-users.xml file automatically not manually

alsoumhi — Tue, 03 Nov 2009 10:16:55 GMT

Hi guys, I am trying to restrict users to access the sources of my application so I have used tomcat-users.xml file , but later I will be facing a problem which is how if I have a lot of authorized users , so I will add each one to that file manually , i think it is not efficient way . Furthermore , I am having an application that lets users used its resources based on the user account in database. if the user has an account in database he/she can login to the application and use the resources , so how can I use this idea with tomcat-users.xml just to avoid the increase number of authorized users in tomcat-users.xml
I hope you understand my question . I don't mind to repeat it again if you have any question
please help me guys because I want to prevent unathorized users to access directly using URL in my application
thank you very very very much

Help with GET method please

kellybaz — Mon, 02 Nov 2009 21:10:24 GMT

Hello- I am pretty new to JSP

I need some help with a GET method. Apparently IE has a URL length limitation..

IE0- "If you are using the GET method, you are limited to a maximum of 2,048 characters, minus the number of characters in the actual path."

By sending all the variables I was hitting the IE browser limitation on length of GET parameters (URL length). So I attempted to shorted it up a bit by taking out some variables that are sent in the handoff template. It's no longer a long url issue, but it still does not seem to work right. Can someone take a look at my code and see if I am doing something wrong?

Thanks!

Session.isNew() problem

blindkilla — Sat, 31 Oct 2009 21:02:40 GMT

When my servlet creates a session, even if it is the first time running the servlet, the session.isNew() returns false. I checked to make sure the session ID's are different each time I run it and they are, yet isNew() still returns false.

I'm trying to do the following in my servlet:

HttpSession session = request.getSession(true);

if (session.isNew())

{

                ...do something...

}

It never gets into that if statement because it always returns false :S

Any help would be appreciated.

I tried this:

        if ((String) request.getSession(false).getAttribute("sessionStatus") == null) {

            response.sendRedirect("Login?pageTimeout=yes");

But it doesn't work... The target remains the same.

Hi,

I would just like to know if it's possible to ping a certain port from a jsp page.
For example:

If I had a Apache_Status.jsp on my machine and I wanted to ping it on another machine at:
123.456.78.90:8080

And I had a Glassfish_Status.jsp on my machine and I wanted to ping it on another machine at:
321.654.87.09:8484

Would this be possible?

Thanks,

Login Validation

camilia — Thu, 29 Oct 2009 01:49:33 GMT

hi, does anyone know how to do login validation using java...here is my code,bt i cant validate if the username and pw typed are the user in the database.

(The java code that i wrote)

public int Login(Friend fr) throws EventException

        {

                Connection con = null;

                System.out.println("Database connection succeeded");

                String sql = "SELECT * from CUSTOMER WHERE userName =? and password =?";

                PreparedStatement ps = null;

                

                try {

                        con = getConnection();

                        ps = con.prepareStatement(sql);

                        ps.setString(1, fr.getUsername());

                        ps.setString(2, fr.getPassword());

                        System.out.println("at select statement");

                                                ps.executeUpdate();

                        

                } catch (SQLException e) {

                        throw new EventException(e.getMessage());

                }

                finally {

JSP and Calendar View

silhoutte — Tue, 13 Oct 2009 11:26:28 GMT

Hey,

Currently I am doing an assignment building an enterprise web application. One of the specification states that I need to make a calendar view of a booking system in JSP. Is there a library out there that help me doing this?

Calendar view here is a page that represents a month and it has a table with 31 cells in it representing 31 days. Inside a cell, if there is a booking, then display the booking title.

What I'm looking for here is just a library that can handle the presentation of the data. The collecting data process itself is not a problem for me.

Technology used
- EJB
- JPA Hibernate
- Struts
- Netbeans and Glassfish :)

Any idea? Thanks

jsf navigation&database connection
ceyesuma — Fri, 09 Oct 2009 03:42:57 GMT
Topic

The topic of this question is: JSF_navigation and database connection

Hello and Thank you in advance for any assistance.



 

System info:



Netbeans6.7.1,jsf1.2,two MySQL databases.(one for login one for searches)



 

The purpose of this post is: 



Try to get the login jsp to switch to the next page and understand how to connect to the database to simulate a login .





 

The functionality of this code is:  



I have two databases one for login and one for finding contents of several music book records. Searches performed via artist or song. The first order of operation is Login.jsp which submits the user name “uid” (user Name and password are the same) and are validated simple uid>8 characters. Upon login the login.jsf page should navigate to the success.jsp or fail.jsp via faces-config file . The login.jsp submits to the controller, the controller calls the model to validate and connect to the splashbookdb_user database. that’s all for now.

(the design of the code does absolutely nothing now.  I just can’t get the connection worked out.) 



(jsf pages,SplashbookController.java,SplashbookModel.java and Content.java (entity).



I will be updating the splashbook project periodically at:

http://cid-b5cb457363230793.skydrive...20-%20Copy.zip



The errors related to this code are:

Connection is reset in client side for only pages that show information stored in dat

alsoumhi — Thu, 08 Oct 2009 09:10:39 GMT

hi experts, hope you are fine.
I am having a connection problem from client side to my servera(localhost:8080/project). client can access to my normal pages either jsp or html. However, for the jsp pages that show information stored in database , they are not appeared in client side and I got message say "connection reset while the page was loading"
please could you help me , in how to let these pages read information from database quickly and thereby will be shown in client side

The file could not be written

Web Server: Sun Java System Web Server 7 update 5

I have inherited a JSP application and am trying to get it to work. I have figured out that it has something to do with the

tag, because I cut all the rest of the code out.

On submit, I get the following error:

 javax.servlet.jsp.JspTagException: The file could not be written: java.io.FileNotFoundException: C:\WebApps\gpr\uploads\attachments\5217\c\DocumentsandSettings\gzjs4n\MyDocuments\227342050034.xls (The system cannot find the path specified)

        xephyrus.taglibs.fileupload.WriteTag.doEndTag(WriteTag.java:103)

        org.apache.jsp.att.attach_jsp._jspService(Unknown Source)

        org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:80)

        javax.servlet.http.HttpServlet.service(HttpServlet.java:917)

        org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:373)

        org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:457)

        org.apache.jasper.servlet.JspServlet.service(JspServlet.java:351)

        javax.servlet.http.HttpServlet.service(HttpServlet.java:917)

        com.cj.trim.trimFilter.doFilter(Unknown Source)

Notice how the error is referring to the file name as "C:\WebApps\gpr\uploads\attachments\5217\c\DocumentsandSettings\gzjs4n\MyDocuments\227342050034.xls". Basically, it is adding the whole (including path) name of the file instead of just taking the file name, which is "227342050034.xls". Since I have no other code creating this name, I do not know why this is happening.

Note: this could be a configuration problem, since I set up the Web Server myself and have not had any other experience doing this.

Am trying to enhance the servlet so that i can simulate multiple purchases. Is there a way in which i can modify this servlet so that it can allow me to allow at least 3 products to be bought? Thanks for any help to be rendered.

Excel report problem in Servlet

Xessa — Mon, 05 Oct 2009 11:06:15 GMT

I have a Servlet and JSP page.

I invoke a method with form submit and the method is a java method.



response.setHeader("Content-Disposition", "attachment; filename = report.XLS");

                response.setContentType("application/vnd.ms-excel");

                response.getWriter().write(result);

                response.getWriter().flush();

Everything works fine but it tries to fit the columns in 1 page. So i have a long adress information.

The adress information is like this in the report.

XESSA IS TRYING
TO LEARN EXCEL

I want to see it like this in the report.

XESSA IS TRYING TO LEARN EXCEL.

I want it to have always 1 row length even it is as long as a novel.

Problem uploading files into the Web-Inf folder

Hi,
I can upload my files outside of the WEB-INF folder and to the path specified but am unable to upload them into the WEB-INF folder. I hope someone can point me in the right direction. Thanks!!

Dynamic page titles

633shane — Thu, 01 Oct 2009 14:03:00 GMT

Hi All,

This is my first post on here so please be gentle with me!

We have a website that provides new car prices instantly to customers. One problem we are having is that Google (we think) does not like our 70000+ duplicate page titles.

Those pages come from our database, a page for each vehicle available from all the leading manufacturers. They also have a page for standard equipment, technical info etc etc. So all of the pages are different content but have the same Title tags and Meta Descriptions. The main thing I would like to resolve is the page titles, the meta descriptions I am hoping will just be a case of applying the same principles.

To do this and make each page have a different title it would be a good idea to pull through the make, model and derivative of the vehicle and put that in the page title... is this possible?

The site already generates a page title dynamically depending on what page you are on but they are all the same for 'technical info' or 'standard equipment'. I would like to add to that title calling information from another table in the database that holds the info about the vehicle in question.

To make this clearer...

Current page title 'Choose any optional extras now - Free Quotes for New Car Prices' - the first part of the title is pulled through dynamically but the second part appears on all pages (is static).

I will remove the static part as it is not really of any use...

What I would like the new title to look like is 'Choose any optional extras now - Audi A3 1.9 tdi SE 5dr Auto'

The vehicle info like I say is held in another table in the databse.

Could someone please help me achieve this? I am happy to post snippets of code if it will help, and give more information on database names and fields etc.

Very much appreciate your time for reading this!

Regards,

Shane

Do we want Java web development starting thread?

peter_budo — Wed, 30 Sep 2009 16:57:50 GMT

I would like to know if people would be interested in participating building similar starting thread like we have in Java section Starting "Java" [Java tutorials / resources / faq], but targeting Java web development.

This thread would hold resources (where to get the things, configurations, basic usage and any tips&tricks) in regards of servers (Tomcat, GlassFish, JBoss, and others), databases (Oracle, MySQL, PostgreSQL, HSQLDB, and others) and available web technologies(servlets, Java Server Pages, Java Server Faces, JavaServer Pages Standard Tag Library and others).

Additional comments are welcome.

no-Cache Control in I.E causing back browser to show page not found

ankitjain_dce — Mon, 28 Sep 2009 17:41:57 GMT

Hi All,
We had an issue in our project that one user was able to see each other's data, we identified the problem as of caching by the proxy server of those users.
On checking we found, we were not specifying any caching preference in our server side code and have learnt since then that by default many proxy servers and almost all browsers cache the data.
After looking on net, we fixed this issue by adding following code in all load actions of our jsps:
response.setHeader( "cache-control","no-cache,no-store, must-revalidate, max-age=0, proxy-revalidate, no-transform, pre-check=0, post-check=0, private" );
Now on doing browser since page was not cached back browser will have to come to server again and this is what we desired.
This is working well in Mozilla but not in I.E(atleast not in i.e.6)
In I.E., we are getting page not found and on refreshing the page an expired page message, on one more refresh it works.
But is there a way that we can make back browser work in all browsers w/o user getting page not found or page can't be displayed?
Also best solution for us will be if page was cached only for one user and for next user ist should go to server, i was hoping "private" control of cache would so, but it also doesn't seem to be working in I.E .

Thanks.
Ankit

package javax.servlet does not exist :>

wildheart25c — Sun, 27 Sep 2009 15:18:50 GMT

you've read it once you've read it a thousand times! probably responded to it just as many times. Now i ask that you respond one more time
I've added as many details as possible becuase i've tried the solutions in an old thread in this forum but no luck.

http://developers.sun.com/mobility/m...les/tutorial2/ <= I'm following what they're telling me to do step by step but i get JAVAC NOT RECOGNIZED when i try to compile the code from that website. It's called Writing Servlet Source Code

1- I downloaded TOMACAT zip and unzipped it in my C drive => C:\jakarta-tomacat-4.1.31 Contents of hte zip are inside this directory.

2- I went here C:\jakarta-tomacat-4.1.31\webapps\midp\WEB-INF\classes and put a copy of that java file here. I created the directory midp and its subdirectories.

3- I went to C:\jakarta-tomacat-4.1.31\bin and pressed STARTUP. Now the server is running.

4- I started a prompt and did as I was told where i set the path then i tried JAVAC and i failed.

5- I went to ENV vars. There was no classpath. So i created one and added its value as C:\jakarta-tomacat-4.1.31\common\lib\servlet.jar

6- I closed the prompt and the server then tried again. Failed.

7- I tried going to the directory where my java file was and then tried javac and still i failed.

8- I started NetBeans and checked plugins. To my luck, and surprise, i found tomacat plugin which I installed alongside another plugin called WebSomething. It says that this plugin will be installed as well since its dependant on it.

9- I went to TOOLS then OPTIONS then MISCLANEOUS and pressed ADD JAR/ZIP next CLASSPATH and put this C:\jakarta-tomacat-4.1.31\common\lib\servlet.jar

10- I started a new prj and created a java file with the same name as the one in the site. I copied hte code too. Red lines appeared on almost every line of code. Like import javax.servlet.http.*; was underlined and the tip said package javax.servlet does not exist

So what now? I tried to make my post as detailed as possible. If you have a solution plz let me no. and in details if you plz :D
My jdk directory is C:\Program Files\Java\jdk1.6.0

Red5 and MySQL

lukethedrifter — Sun, 27 Sep 2009 11:16:48 GMT

I know this contains actionscript, but the server side is Java. I am trying to get a red5 server to insert into mysql, but I can't get eclipse to compile this client side code.

Could someone tell me if this tutorial is up to date with galileo, the new version of eclipse? I can compile through the flex redistro (mxmlc.exe command line), and I can get the Java server running, but I do not know how to compile this client code:

http://www.actionscript.org/resource...ver/Page2.html

without the necessary flex xml to compile in the flex sdk (mxmlc.exe --strict)
