java.lang.LinkageError

[gopi.mu...@mutualofomaha.com]

Can somebody help me out on this issue. I am struggling with this error last 3 days on Portal 6. My server starts fine but I can't see my login page due to the following error. None of my applications using xml.jar and I have deleted all xml.jars except one.

com.ibm.wps.engine.Servlet init EJPFD0016E: Initialization of service failed.

have you added any libraries to the appserver lib? or anything it looks like there are jars with the same class files and it is loaded once, and then tries to get loaded somewhere else from a different jar and it fails with the error you are getting
