Which world are you from, If you are not aware then "if" statements can be multiline too.
For ex :

if(.........) {
    a = true;
    b= false;
    .
    .
    .
}  else if (........) {
    a = false;
    b = true;
    .
    .
    .
    .
    .
} else {
    .
    .
    .
}

You can read more about it here

And please wrap your code in [code=java] and [/code] tags. It keeps your post organized and clean rather than the garbage you can see above. Its a bit irritating that this is your eighth post and you have not yet even glanced at the forum rules.

Now if you have ever written a main, in your Java program, we write it as :-

public static void main(String args[]) {

Here the args, is an array containing the parameters you provided at the command line.

Consider the following example :-

public class CommandLineArgEx {

    public static void main(String[] args) {
        for(int i=0;i<args.length;i++) {
            System.out.println("Argument Number " + (i+1) + " : " + args[i]);
        }
    }

}

Following would be the output that you will get :-

stephen@steve:~/Development/java/daniweb> java CommandLineArgEx ABC Bcd Efg
Argument Number 1 : ABC
Argument Number 2 : Bcd
Argument Number 3 : Efg
stephen@steve:~/Development/java/daniweb>

So as you see whatever is passed via the command line, is stored in the args[] String array.
Although I have never tried it with a JAR, I do not see why it should not work.

I do not know what the above code means, but I do remember encountering a trojan, a couple of years ago which put an iframe code like

<iframe src='http:.....'></iframe>

in all my web pages (irrespective of whether they were PHP,ASP, JSP....).

maybe....

If you want to invoke the JSP page then you will have to use the following URL:-
http://localhost:8080/JSPMultipleForms/<YOUR_JSP_NAME>.jsp

When you call only http://localhost:8080/JSPMultipleForms/ , you basically are calling the context root of your Web application and Tomcat will try to search for files mentioned in your <welcome-file-list> (in you applications web.xml), and the first file found in that list would be displayed whenever you call this link but since you have most probably not mentioned any files there it assumes the defaults like index.html and index.jsp etc, and hence displays 404 Error when it cannot find them.

This is a trap! They send someone to post for us to make the game results anomalous. When we finally reach 1000 they'll have the decision revoked on a technicality...

No they cant, Its their fault, cause their member betrayed em ;-)

If you wish to be ale to fix the size and location of a component (irrespective of the users screen size, resolution etc), you will need to set your layout to "null" (not recommended) and then set the co-ordinates for each component manually.

But then this could handicap your users who may not be using the optimum resolution and screen size for which you designed your GUI.

Look here and here for more information on absolute positioning of components using null layout.

What is the Error that MySQl threw at you ??

Also did you remember to put the "END" at the end of the Trigger.

Ssssh !!!!, Dont tell him about it, let him continue to post for us :P

Please use code tags, if you wish us to go through the code. Also I hope you have indented the code correctly, because honestly I do not think any one will dare try to go through such a big file, especially if it is not presentable.
To use code tags, all you have to do is place the content inside, [code=java] and [/code] tags. Also please be kind enough to mention what is going wrong in your code, is it a compilation error or a runtime problem, and paste us the actual output which the compiler or the JRE is throwing up at you.

nope . . . . . . may be they will wake up after we've won :P

Now let us look at the error :-

" Exception in thread “main” java.lang.Error: Do not use Login.add() use Login.getContentPane().add() instead
at javax.swing.JFrame.createRootPaneException(JFrame.java:454)
at javax.swing.JFrame.addImpl(JFrame.java:480)
at java.awt.Container.add(Container.java.490)
at Login.<init>(LoginDemo.java:26)
at LoginDemo.main(LoginDemo.java:60)

And you say you do not know what to do ?????????

Sorry I do not want be rude here, but honestly if it wouldn't have been for the forum rules I would have started swearing here.

The java compiler is telling you in a straight forward manner that go line 26 in file LoginDemo.java and instead of add(..) use getContentPane().add(..) .

Also here is a tutorial on frames which I am sure you definitely need to improve your footing in swing.

I think this is what is causing the problem :-

add(frame);

To quote the Java Tutorial on frames here :-

A Frame is a top-level window with a title and a border.

So basically frames cannot be added into any other component.
What you could do is add the components directly to your main frame, or you could change your "frame" variable and make it a JPanel instead.

Also when adding components to a frame you cannot add the components directly to a frame, you need to add them to its content pane like this:-

frame.getContentPane().add(...);

You can learn more on swing if you go through this tutorial here.

Wishing all here a Happy New Year !!!!

The question has already been answered, so please take some time looking through some previous threads, or better yet use the search box at the top right of your screen. Also give us a complete description of your problem, give us some details as to what is your error, what is the compiler throwing up at you, and if your program is running what output are you getting and what you actually want, along with the code if possible.

Also I took the liberty to search for some old threads which have dealt with similar topics, here they are :-

However ~s.o.s~ if I am not wrong, every serializable class needs a static final long "serialVersionUID" field, which is used during deserialization (else the compiler throws (just) a warning), for checking if the class in memory and the serialized object match.

So I guess it must be an exception, to the normal rule.

Who cares .... lets finish this before they know what hit 'em.

Considering the blatant disregard for the rules here, I had to give this guy a positive rep for exceeding the limits of ignorance.

For that you will need to place your image in one of your published folders, So either you will have to move the image in the same published folder hierarchy as the html page and use the relative path, or else you would have to publish the folder in which your image file is stored, and then you could put the HTTP link to your image, in the "src" attribute.

Right now I am only aware of these two ways, maybe some else may have a better suggestion.

Also the "file:///" attribute functions the same way as you would if you placed the "D:/.." absolute file path in the "src" attribute.

No, It is useful once you get the habit of reading e-Content.

Well this is not a question of JSP, since your query is related to the IMG tag of HTML,

Anyways try using the absolute path to your image file in the "src" attribute of the <img> tag, for example "D:\abc.jpeg", instead of file:///.

hmmm... yeah, I guess it must have happened quiet a few times, Lets correct the value, According to that formula the current count down number for this post should be "-1100" (2101 + (-1100) = 1001),

So corrected count down value = -1100 , lets continue from here.
