| | Insert line breaks in server side code, in your case that being ASP. The formatting will be preserved as it is in the textarea. Your rendered textarea should look like: [code] <textarea cols="55" rows="10" name="txtDescription">Location: Atlanta-30th Floor-3034B Occupant: Andersen, Jason Current Station Type: Floor Shared</textarea>[/code]  |

| | Will code for money; it doesn't matter whether it's C, C++, Java or C# as long it's a general purpose, fairly famous programming language. It's my job to churn out quality software which I think I am quite good at, though I must agree the language you program in greatly …  |
 | Re: Game Engine I disagree. Even after all these years, Java still has to go a long way when compared to C++, at least in terms of Game Development. The kind of raw power achieved by C / C++ _can't_ be offered by Java. Compare and contrast the implementation of different languages in … |
| | Use the Apache commons upload library to ease the task of image uploading. Once you get hold of the image, store it in the database as a BLOB (Binary Large Object). and retrieve it back as a stream of bytes which can be used for recreating the image.

 | > Is this possible? Yes, very much possible. Use the DOM API. Below I present a minimalistic code snippet which replaces a button element with a text element. [code] <html> <head> <script type="text/javascript"> function change(elem) { var newElement = document.createElement("input"); newElement.type = "text"; newElement.id = "txtName"; newElement.name = "txtName"; elem.parentNode.replaceChild(newElement, … |
| | Re: how to get You need to use Ajax for it. There are many decent Ajax frameworks out there which you can use with a minimalistic knowledge of Javascript. Your query is by far too generic, post your code if you get stuck and we might be in a better position to help you … |
| | Which record are you talking about anyways? Please make an attempt to at least specify the exact nature of your problem as explicitly as possible instead of letting the one helping you out to do all the thinking. |
| | > The following works correctly in IE7 but doesn't work in Firefox. Any idea? Because you are trying to retrieve the element using the id "testfield" but you don't have any element having an id "testfield", only one with a name "testfield". It works in IE because IE approximates or … |
| | Look into the RandomAccessFile class. The only downside being the file is a treated as a sequence of bytes rather than the conventional line oriented view which many are used to. This class is especially for example useful when you want to come up with your custom file format which … |

| | Involving javascript for doing automatic number generation is the worst choice you could have made. Just allow a [URL="http://java.sun.com/blueprints/corej2eepatterns/Patterns/DataAccessObject.html"]DAO class[/URL] of that specific table handle the job of automatic number generation which would typically be exposed through some function like getNext(). |
| | Accessing the database from JSP which is meant for display / view purposes is a bad practice. Put all your database access code in a servlet which would then set the retrieved data in a session or request scoped variable which would then be accordingly rendered in the JSP file. … |
| | An option would be to use the Java library iText to convert the given text to PDF which can be then written back to the browser. Generating image from text seems to be a pretty complicated task; something which I haven't personally tried out. Maybe [URL="http://today.java.net/pub/a/today/2004/04/22/images.html"]this [/URL]article will help you … |
| | You will have to cast it to the reference type you are expecting it to return. This is because the specifications say that getAttribute() returns a variable of type Object which of course makes sense since it enables us to store a reference variable of any kind. Maybe something along … |

| | AFAIK, a session object is automatically created as soon as a request to a resource is made. In the Servlet API, you can get hold of the session object using request.getSession(), which grabs hold of the session for the current request. The way the session is maintained i.e. either by … |
| | Use the SimpleDateFormat class to parse the string into a Date object. Feed that Date object to the instance of the Calendar object and use it's function roll() to do the dirty work for you.

| | Your problem seems to be this line in your JSP file: > [icode] <%@ page import="mybeans.processFormBean" %>[/icode] What exactly is processFormBean here? Is it a package? Are you trying to import all the classes from the processBean package? If yes, then you are doing it the wrong way. To import … |

| | > I know I'm probably being dumb here but I cannot seem to compile a java bean. You are missing a static import in your package declaration. [icode]import static System.out;[/icode] |
| | Don't use statement, use PreparedStatement. Date can be stored database table using either java.sql.Date (only for dates) or java.sql.Timestamp (for date along with time). Read the [URL="http://java.sun.com/docs/books/tutorial/jdbc/index.html"]JDBC tutorials[/URL] for more details. Also each SQL implementation (i.e. each database) has it's own specific way of generating the current date, so if … |

| | Re: JSP if statement The == operator in case of references compares the references and not the values to which they refer. Since both id and key don't refer to the same string instance in memory, it always returns false. What you need here is to use the equals() method to do the same. … |

| | This is because you have specified a relative URL and with you currently in the "shipper" context, it's trying to find "UploadUnconfirmedSOServlet" in that context. What you can do here is either make use of absolute URL's or adjust your relative URL to suit your needs. Something like: [code] <form … |

| | Yes, [ICODE]request.getParameter()[/ICODE] always returns a string unless you plan on challenging the API. As far as date is concerned, you can decide on a format which you would be expecting from your users. At the server side, pull the date values entered by the user as a string, try to … |

| | Use the [URL="http://www.quirksmode.org/dom/getstyles.html"]getStyles [/URL]function to get the CSS property of an element. You would probably get the width of the element in pixels but that should work fine for you.  |
 | Your code is far from being a proper XHTML document, but works in IE, since its really forgiving. A few things: [LIST] [*]All the form elements should go in the form tag. Its only when they go inside the form tag, a name attribute given to them is valid, otherwise … |

| | Re: define variable [quote=Ancient Dragon;306807]Probably not because such a class still has all the properties of double data type.

| | Try [ICODE]document.forms[0].elements['yourElementName'].focus()[/ICODE]. Don't use [ICODE]document.all.[/ICODE] It's not a standard property of the [ICODE]document[/ICODE] object. And having a 1.8K line source file is bad in itself IMO. |
