[jdom-interest] Using JDOM with Microcoft Java VM + Internet Explorer (Fixing NoClassDefFoundError) (Archive purposes)

Wouldn't you just place the JDOM and parser files in the codebase
location of the applet? It seems kind of baked to have to edit the
registry to run an applet.

OK - Thanks Ian for the comment that sparked the idea - I was able to
get things working.
Here's what I did to get it working, in case this saves anybody time in
the future. From what I was able to gather from reading the archives,
if you're getting NoClassDefFound errors, then your compiler or runtime
environment doesn't know where the proper .jar files are.
solution: set the path so that the compiler or runtime environment can
find it. For normal Java Apps, apparently this means setting the
CLASSPATH environment variable.
I was getting this error when trying to run the program as an applet
under Internet Explorer, but it compiled fine, since the classpath
included jdom.jar and xerces.jar.
So, set the Classpath for Microsoft's VM open up the registry editor
(start->run->regedit) and go to the key:
MY Computer\HKLocalMachine\Software\Microsoft\Java VM\ClassPath
edit that to include a path that points to your jdom.jar and any
other.jar files you need. Mine only worked when I hard-coded the path,
using %JAVA_HOME% didn't work for me for some reason.
Save it, and retry your app - it should be OK if you've gotten the
correct paths. For example's sake, here's what mine looks like now:
I hope this helps somebody in the future...

I'd say it HAS to be because jdom.jar isn't being found at runtime. Are
you absolutely, completely, positive it is in the classpath used at
