Hi Daniel,
These two webservice clients are not being packed in ear. These are two different web applications packaged in different wars.
I am suspicious that, this is being purely a class-loading issue occurring because of initialization of one of the client halting the work of other.
Now I have bundled all supporting jars together in both the web application specially webservice-rt.jar. I am monitoring this problem, not it was occurring very rarely. but still the problem is not resolved.
Can you please assist where to look.
