Anyone here could try to guess but that is waste of time as we don't know your configuration but support staff does know so engage them( CICS Web Service and Java) and give what you know so far and then post back the solution to us so that anyone else with the same issue can be benefited. This has more to do with classpath configuration ( My guess)
Thanks for your response. I have checked with Support initiailly but they had no clue on this.
My class path is set to /usr/lpp/java/J7.1_64/bin and I have manually checked a few of the similar location looking for this main clause but no luck. Can you suggest some possible locations so that I can give a try. Thanks again
