Did you ever find yourself writing terse code in Java, C# or C++?
If so, why? Do you think there are any situations in which this should be acceptable, given the situations in which these languages are used?

How do you get Eclipse to work properly with JSP files as it does with Java files?
Specifically:
Eclipse "Find references" (Right click on method, references, workspace) doesn't find references in JSP files.
Eclipse refactoring (Right click on method, refactor, rename) doesn't rename references in JSP files.
We're using Eclipse 3.2...
I'm trying to establish whether we are better off rendering charts serverside and pushing them to the browser as images or using a javascript charting library to draw the charts clientside.
I'm looking at the JFreeChart and Dojo Charting libraries, my target is an existing JSP site that runs in JBoss.

Hi, I'm setting up CCNET server to run Selenium tests. In my test code I use the following to start the Selenium RC server if its not running:

What I noticed is that when I have a string type with enumerations, for instance, in my case the stepType, with values starting with a numeral, JAXB does not generate a separate enum class say StepType class. It works fine, when I use only alphabets for the valu...

My questions are:
What is the encoding of the userData? This is a trick question, since Strings in java are sto...

Hi all,
I'm mantaining a EJB 2 CMP legacy app runing on a JBoss 4.0.4 GA application server with deployed entity/stateless session beans. All the EJB boilerplate code is generated via XDoclet from the EntityEJB/EntityEJBManager annotations.
I've noticed that when my GUI client invokes the facade create method, I have lots of cases of E...
I'm building an application using a JPA object model, and creating several Data Access Objects to interact with that model. I'm finding that I'm repeating a lot of code (essentially CRUD) between different Data Access Objects. The only thing that differs are the targeted JPA classes.

g2d.drawString("Pause", (int) ((800/2) - ((Font.getSize()/2) * 5)),270);

I'm not interested in any other information (which key was pressed, application used, etc.). On...
