For my university assignment I have to make a networkable version of pacman. I thought I would best approach this problem with making a local copy of pacman first and then extend this functionality for network play. I would have to say that I am relatively new to java GUI development and utilizing such features within java. http://ww...
I'm soon going to check in the very first commit of a new Java project. I work with Eclipse Ganymede and a bunch of plug ins are making things a little bit easier. Previously I've been part of projects where the entire Eclipse project was checked in. It's quite convenient to get the project settings after a check out. However this appro...

This questions is prompted by http://stackoverflow.com/questions/444638/strange-hashmap-put-behaviour#444757 I think I understand why Map<K,V>.put takes a K but Map<K,V>.get takes an Object, it seems not doing so will break too much existing code. Now we get into a very error-prone scenario: java.util.HashMap<Long, String> m = new ja...
I am trying to find out why Apache CXF is running away doing "something" upon first-time initialization of a web-service. "Something" is probably some kind of IO, and I'm guessing it's trying to resolve an external address/schema/DTD of some sort. So I'm trying to find some kind of hook where I can monitor all IO. Either at VM level or ...
I'm using the Flamingo ribbon and the Substance Office 2007 look and feel. Of course now every control has this look and feel, even those on dialog boxes. What I want is something like in Office 2007, where the ribbons have their Office 2007 look, but other controls keep their native Vista/XP look. Is it possible to assign certain con...

I'm working for the first time on a project that requires building a webapp which makes heavy use of JSF (and ICEfaces in particular). There's a mix of stuff to be coded including CSS, HTML, JSP/Java and, of course, JSF. I'm doing all this within Eclipse btw and using a local tomcat server which eclipse is responsible for launching in o...
Hello, It seems I don't understand javascript callbacks quite as well as I thought. In the following example, I would think that each copy of function in setTimeout would refer to its own copy of the variable "index". Therefore, running the example should produce the following alerts: "zero" "one" "two". var array = ["zero", "one", "t...
