Iam getting this exception when the unmarshalling the response on the client side and client has com.customer.ABCCustomer in the class path .... switched on classloader option and initilized com.customer.ABCCustomer on the client side and was able to see the class getting loaded.

Problem is when client is unmarshalling the response.


java.rmi.UnmarshalException: failed to unmarshal interface java.util.Set; nested exception is:
java.lang.ClassNotFoundException: Failed to load class com.customer.ABCCustomer

This is issue with the weblogic class loader .., copied ABCCustomer.class which in the one of our jar files into the domain\lib dir and it started working ..., this is just a work around .., hopefully weblogic gives us some fix of this ...

the reason for above error mainly because in some java file which implements Serializable interface has been changed you can revert those files to previous version
