Hi All,
I am working on GWT+Spring+Hibernate integration. But I am getting the
following error. Could any any one please help.

java.lang.RuntimeException:
com.google.gwt.user.client.rpc.SerializationException: Type
'java.lang.IllegalArgumentException' was not assignable to
'com.google.gwt.user.client.rpc.IsSerializable' and did not have a
custom field serializer.For security purposes, this type will not be
serialized.: instance = java.lang.IllegalArgumentException: node to
traverse cannot be null!
