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:

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 ...
 
It is sorta covered in the JavaRanch Style Guide.
