I hate this problem, a number of people at work have been up against the 
same thing, and the fix rarely seems to be looking at JAVA_HOME as 
indicated. I think the problem is with Eclipse and not JSword.

Here is what I do to get it working on windows (which is the only place 
I've seen the problem).
- Install the latest JDK.
- Set JAVA_HOME to point at the install dir (not the bin dir)
- include %JAVA_HOME%/bin in the PATH
- Close *all* the environment dialogs
- Check that after opening a *new* command shell and typing "java 
-version" yuo get the correct number.
- Ensure there are no java.exe files in c:\windows or 
c:\windows\system32 (or whatever they are called on your system)
- Check in HKEY_LOCAL_MACHINE/Software/JavaSoft/Version# that stuff is 
pointing at the right place and the default key is a sensible version 
number.
- Restart Eclipse and have another go
- Give up and use a batch script instead

Any of the above checks *could* fix it, or maybe none of them will, but 
it is worth a try.
