However, on our server, running the same version of JBoss, when I stop the instance, delete the WAR file, upload the latest version, and restart JBoss, it won't show ...

When I was programming a Form Validator in PHP, when creating new methods, I needed to increase the number of arguments in old methods. When I was learning Java, when I read that extends is to not touch previously tested, working code, I thought I shouldn't have increased the number of arguments in the old methods, but overridden the ol...
I have ten WAR files, all of which have nearly identical code and markup. The only differences lie in the images, CSS and Messages. I hit on the concept of Profiles but I haven't quite groked it yet and I'm not sure if this can handle what I need it to do. Basically, I want a base project with different profiles for the 10 different WAR...

I work with RDF and OWL but until I came to SO I'd never heard of Rowlex and OwlGrinder. It's got a much larger presence on SO than Protege or Pellet (although from a smallish number of active people). Is it primarily the .NET equivalent of Protege or does it take a different approach (It stresses the Open-world assumption). There's very...

However, when executing the same code on our test environment (Linux based), iText throws an exception claiming the image file "is not a recognized imageformat", in com.lowagie.text.Im...
I'm looking for the Clojure/Java equivalent to Python's lxml library. I've used it a ton in the past for parsing all sorts of html (as a replacement for BeautifulSoup) and it's great to be able to use the same elementtree api for xml as well -- really a trusted friend! Can anyone recommend a similar Java/Clojure library? About lxml ...

How would I force a Frame to repaint() immediately after it is maximized, or resized? I can't find what method is called when that specific operation takes place. I have a bunch of graphics that are written with Graphic objects in paint and their orientation depends on the real time feedback from getWidth() and getHeight() but paint isn...
Say I have something like this: new File("test").eachFile() { file-> println file.getName() } This prints the full filename of every file in the test directory. Is there a Groovy way to get the filename without any extension? (Or am I back in regex land?) ...
I understand that C++ is generally considered better than Java for games (at least larger-scale games). Why is this? What is keeping Java from being competitive in this field? Which reasons against using Java for game programming have the most basis, and which ones are myths? EDIT: Am a bit unfamiliar with C/C++, and did not think to ...
