[rules-users] BRMS Insurance Sample - InvalidClassException

Folks,

I'm working through the BRMS insurance example (the very last section in 
the Drools documentation). I can build ( the example) and deploy both it 
and the BRMS ok. I import the repository , rebuild the snapshot binaries 
(BRMS), then hit the 'Continue' button on the drools insurance I get the 
InvalidClassException (below).

I remember testing this for Edson and Ferando a couple of months back, 
so it could be something stupid that I'm doing. I'm running JBoss 4.2.1 
, Java 1.6.0_03 on Windows Vista.  I'm currently using BRMS 4.0.4 , with 
the insurance example from the Trunk (4.1.0 Snapshot),

Other things I've tried:
1) All combinations of latest stable 4.0.4 and Trunk (including the 
obvious 4.0.4 for both, and the snapshot for both)
2) I've extracted the fact classes from the insurance war, made a 
standalone jar, and imported these into the BRMS
3) I've check the URL that the Insurance example uses, and modified it 
to take ' /LATEST'.

Michael (thanks for the earlier suggestion) : Is this (number 2) what 
you meant by updating the Jars? Any other suggestions that I can try?

Thanks

Paul
