Hello List,
I'm trying a Grid Service called from a OGCE Portlet.
When the following line is executed:
------------------------------------------------------
endpointString= ObjectSerializer.toString
(instanceEPR,MYSERVICEQNames.RESOURCE_REFERENCE);
------------------------------------------------------
get an "Serialization Failed Exception".
The instanceEPR object is not null, and get the following
stacktrace:
-----------------------------------------------------------
Serialziation failed. Caused by java.lang.NullPointerException

-----------------------------------------------------------
When i use and standard client (not a portlet) the serialization
works fine.
Could you please help me to find the error ?
Thank you in advanced.
Julio.
