Sorry, I didn't see you answer. This is going to become an agony. I cannot deploy an application (how pathetic is that). I'm not sure I'm understanding you, but EVERY exception occurs in xercesImpl.jar. EVEN if I omit it AGAIN phantom exception occurs, not the same but still against the parsing... I'm completely exhausted , and have no idea what problem is... Changing server is one of solution, but... not ultimately solution... How is possible, that you take an application, deploy it on much 'advanced' tomcat container, and WALLA. The application is deployed successfully without even warnings... Now I'm trying to deploy the same application on the advance hi-tech application, and I cannot perform that for a seven days 12-14 hours a day. So what is the problem, huh?
