Subject Re: Mapping table names with model names
Date Mon, 03 Feb 2014 18:47:16 GMT
The message indicates the entity
org.apache.airavata.persistance.registry.jpa.model.Application_Descriptor
can
not be loaded.

Can you double check if this class is accessible from
"maven.compile.classpath"? Or turn jdk trace to see where classes are
loaded from!
