Just in case anyone is desparate with installation issues on XP...

Starting with the latest releases I had several difficulties with various mixes of installations of JBossIDE and Eclipse, including:
- whitespace issue with HTML-Files (see also Fibo tutorial)
- missing classes
- not able to start JBoss Server from within JBoss IDE

The so far stable setup is for me:
- Windows XP SP2
- JDK 1.5.0 (!!!)
- Eclipe 3.0.2
- JBoss Server 4.0.1sp1
- JBoss IDE 1.4.0

Make sure that the Java environment is consistent:
- check PATH variable to point to JDK 1.5.0
- set JAVA_HOME to point to JDK 1.5.0
- delete all Java executables from the windows folders
- use regedit to set all Java keys to point to JDK 1.5.0
(for example 'HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\Current Version')

Of course the IDE might be outdated, but at least it works (so far...), and I have several other plugins installed. If anyone has the same setup, pls. tell your experience.

So long, MF
