[rules-users] ClassNotFoundException

[Stephen Masters]

Something worth trying (it keeps catching me out) ...

If I have been adding & removing classes from a jar, I see this frequently. I worked out that I need to open my Guvnor package and switch to the "edit" tab. There's a list of "Imported Types". You may well find that 'missing' facts are still in that list, so you just need to remove them.

Basically, if you remove a class from your model, the imported class doesn't get dropped from this list automatically, and you see the class not found errors. When I get these kinds of errors, I generally just remove all classes from that list and re-import the POJO model jar, which automatically re-populates the list with the facts from my jar.
