[rules-users] Re: Invalid signature file

[Geoffrey De Smet]

the drools jars aren't signed AFAIK, so it must be another jar causing 
the problem.

Debug and take a look which jar is being loaded.
In that jar you 'll find a META-INF/MANIFEST.MF file with signed hashes 
and META-INF/*.RSA and *.SF file which is the signing key.

Not that signing an already signed jar corrupts the jar. For example, 
during your webstart signing.

With kind regards,
Geoffrey De Smet
