Java.lang.LinkageError Exception

Question

Hi,
Here is an exception where i have got stuck up. I have been using weblogic9 with myeclipse. I have successfully deployed the application and when i was try to access a page in the application i have been end up with the following exception. Below is the exception message.
javax.faces.FacesException: #{FlightSearchBean.searchFlightOnly}: javax.faces.el.EvaluationException: java.lang.LinkageError: Class javax/xml/namespace/QName violates loader constraints
     at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:78)
     at javax.faces.component.UICommand.broadcast(UICommand.java:312)
I have searched for solution with the exception message on net, but none of the solutions could solve my problem. The problem seems to be with the Qname.class, i think due the duplicate existance of this class in different jar files is the reason for problem. I have followed different approach to load my application specific jar files but none worked. Can any one help me out in this regard where i was lacking. Any help rendered is greatly appreciated. Thanks in advance.
Thank You,
Tarun.

I too have same error with WebLogic 9.2 and Java5. I tried to make sure that it wont load QName.class from app lib but only from container. Still it has issues. Could anybody suggest me the go?
