Unable to solve the warning.

[poonam pac]

Hello,

   As suggested by you I made the changes in my Application developed integrating "GWT+Spring
+Hibernate" in the Hosted mode but still I am getting the same Warning message as :         StandardContext[]Exception while dispatching incoming RPC call

 

Please help me to solve it. I am sending you the detailed Warning message below -

It seems that the answer you return with getPupils (inside the List)
contains an instance of type org.springframework.context.ApplicationContext.
Because that class is not known by the RFC-Response-Encoder you get
this error.

I don't know Spring and the integration with GWT but you can try
getting rid of this instance in the returned classes.
