I’m using Eclipse 3.2. What are you using ?
I’m an Eclipse fan myself, as well. Targeting Java 6.
Out of curiosity, is there any reason you’re using Eclipse 3.2 instead of 3.4?
Eclipse is the IDE, not the compiler.
Eclipse is an IDE (integrated development environment), not a compiler. Afaik it contains an own compiler for the incremental compiling stuff, but the compiler is normally a command line tool contained in the SUN/IBM/Apple Java Development Kit.
If you are asking for IDEs, I use Netbeans 6.1 and I used Intellij IDEA 6.x a lot at work.
I use Eclipse as my IDE as well.
I just use suns compiler. For my IDE I will always use Eclipse.
I use Sun’s compiler, IntelliJ IDEA as IDE, Maven for build management, Subversion for source code version management.
I write my own bytecode :persecutioncomplex:
ROFL
Well some do write in assembly so why not bytecode 
the first few bytes are easy ;D
Yeah, some day I got to hook one up eh?
Oops, I’m terribly embarrassed that I didn’t draw this distinction! :persecutioncomplex: Oh well…
To answer the question properly: JDK6 update whatever from Sun.
I posted this a long time ago, but I know better now lol.
Compiler: Sun’s Java 6 update 13
IDE: Eclipse 3.4.2
Build tool: Maven 2
// Json
IDE: blueJ ;), tried to switch to netbeans once, I just dont like it.
I haven’t used the newest BlueJ, but I found it horrible when I used it. I was so happy when I swapped to eclipse.
IDE: Eclipse
Compiler: Eclipse (the one built into eclipse)
For releases, I sometimes use the JDK one.
I havent updated since, august.
I just like how it is graphic, cause then I dont just have a bunch of tabs, I got a webs with how the classes interact with eachother. and it is small and fast. It takes netbeans like 1 minute to open, and blueJ like 3 seconds.
I also just dont have the pacients to change to netbeans.
Eclipse does have a built-in compiler.
