Reporter: Jens Grassel
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
See below for two example to reproduce this error.
