The application consists of a server WAR and several rich-clients distributed in JARs. The trouble is that it's all in one big, hairy code base, one sourc...
I'm trying to build a Java regular expression to match ".jar!" The catch is that I don't want the matcher to consume the exclamation mark. I tried using Pattern.compile("\\.jar(?=!)") but that failed. As did escaping the exclamation mark. Can anyone get this to work or is this a JDK bug? UPDATE: I feel like an idiot, Pattern.compile("...

I am working on a J2ME project that spawns worker threads for numerous tasks such as downloading HTTP content. The basic thread layout is similar to most java apps--there is a main UI thread and worker threads spawned to do stuff behind the scenes.
