I am using WSAD 5.1.1 on Linux and I have problem

when using SQLJ Java Beans. Everytime I rebuild SQLJ Bean

( Run Ant ..... ) and tried to test Application I got nullpointerexception

on every "sql [ctx] ......." . Refreshed SQLJ Bean (means new compilation )
with no cistomized SER file

works OK , with dynamic SQL of course .

On the other hand , same EAR delpoyed in WSAD 5.1.1 on windows works OK .

In WAS on z/OS deployed EAR causes sqlj.runtime.ExecutionContext: method
getFetchSize()I not found .

Please Help !!!!!!!!!!!!!!!!
