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. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553402#553402] Start a new discussion in JBoss Web Services Metro at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
