I have gwt app with openjpa 2.0
*gwt compiler compile OK *
*Compiling module skladisce.SkladisceGWT*
* Compiling 6 permutations*
* Compiling permutation 0...*
* Compiling permutation 1...*
* Compiling permutation 2...*
* Compiling permutation 3...*
* Compiling permutation 4...*
* Compiling permutation 5...*
* Compile of permutations succeeded*
*Linking into
/home/MyUser/IBM/rationalsdp/workspace/SkladisceWeb/WebContent/skladiscegwt*
* Link succeeded*
* Compilation succeeded -- 129.166s*
but runtime error happend.
Why do I get error serialization?* What does
'org.apache.openjpa.kernel.DelegatingResultList' has with serialization*???
my ERROR:
*com.ibm.ws.webcontainer.webapp.WebApp log SRVE0296E:
