java.lang.NoClassDefFoundError when updating in Weblogic

Weblogic 10.3

Coldfusion 10 enterprise ed.

Hello - I'm trying to find out why when we push an update from our Weblogic Admin server to our managed servers, we receive "java.lang.NoClassDefFoundError: com/rsa/cryptoj/o/bo" when trying to run some of our Coldfusion pages. Looks like it's dealing with the JDBC connections we've set up.

The error will clear up if we bounce the managed server processes. I've read that this error is from the class being available at compile time but not at runtime.

Does anyone know what might be happening?

Thanks!
