Description

Hi,

I've just compiled the current 2.2 release using ant make-core-deps make-deps build and deployed the 3 WAR files into a tomcat server. After running org.apache.manifoldcf.crawler.InitializeAndRegister the database seemed to be populated and the web ui seemed workable.

However, on certain occasions a java.lang.NoClassDefFoundError is thrown.

I've looked into WEB-INF/lib and didn't find the needed classes in any of the jar files there. On the other hand copying the jars into tomcats lib, common or shared directories didn't help either.

Regards,

Jens
