full stacktrace from catalina.out

Hmm, i think the reason is that in branch 1.5.x, the xstream's jar file is old. we should convert from xstream-1.3.jar to xstream-1.3.1.jar in its directory.

Because, in xstrema-1.3.jar, it can not deal with CGLIB-enhanced-proxy's deserialization.

stacktrace for com.thoughtworks.xstream.mapper.CannotResolveClassException: org.openmrs.User$$EnhancerByCGLIB$$fff1cb7d

OpenMRS Version: 1.5.0 beta2 Build 8803

I added the xstream-1.3.1.jar to my local openmrs-branches-1.5.x workspace, ran a clean build, and deployed the new WAR to Tomcat. I was able to save, retrieve, edit a few cohort definitions (serialization and deserialization was working fine). Then on restart of Tomcat, the exception above is thrown on any request that tries to deserialize the cohort definitions that were saved.

I assume this is due to the fact that the classpath has been refreshed and the class org.openmrs.User$$EnhancerByCGLIB$$fff1cb7d no longer exists. We need to make sure all proxy class references are converted back to openmrs classes during serialization.

Please let me know when that is done in the 1.5.x branch.

Thanks,

Justin

Thanks, Justin

In fact, serialization framework in serialization branch will convert every proxy class reference back to openmrs class during serialization. This work has been done in both serialization branch and openmrs trunk 1.5

But, now the only problem is remain that you have described in ticket #1588, In reporting module, while xstream serializer want to convert proxy class reference to openmrs class, it can not get the session and throw an LazyInitializationException.

I think if we can resolve this problem, this problem will no longer exist.

I assume this was cleared up with the serialization.xstream module having all updated serialization code.
