Java EE (Java Enterprise Edition) General Discussion

Hi,

I have a question regarding Axis webservice. I get the following exception intermittently when the axis webservice is contacted from other component.

======================== Exception start =================

========================= Exception End ==================

Our clients continously call this webservice hosted by my component. Sometimes it fails with this exception, most of the times it works fine. Could not make out why this error comes as the host is always up.

Just wondering whether it is some kind of load issue when there are too many webservice requests at a time. If so, how can we avoid this load issue. Is it something which is not handled in Axis 2.0? Upgarding to 3.0 would fix the issue?

In one of the forums I saw the same kind of problem reported. But the answer given was to remove xmlsec.jar.

But I could not find the jar at all in both client, server. Could someone explain how this exception is related to this jar.

Thanks & Regards,
