Problem:

The WebLogic Administration Server does not start with the following exception in stdout logs:

<Critical> <WebLogicServer> <BEA-000362> <Server failed. Reason: There are 1 nested errors: weblogic.management.ManagementException: [Management:141266]Parsing Failure in config.xml: javax.xml.namespace.QName; local class incompatible: stream classdesc serialVersionUID = -9120448469326609940, local class serialVersionUID = 4418622981286495151

 

Background & Analysis:

This is a known problem for Oracle. The problem is actually with the JRockit 1.5.0_07 version (and later) used with WebLogic Server 9.1 or 9.2, in which there is an incompatible change of the serialVersionUID of the javax.xml.namespace.QName class. Refer Known Problems.

 

Solution:

There are two solutions to eliminate the error. You may use any one of the following:

SOLUTION 1: Set a system property as follows:

com.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0

SOLUTION 2: Add the following option to the java command in the script you use to start WebLogic Server:

-Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0

 

Root Cause:

Incompatibility of JRockit 1.5.0_07 (or later) with WebLogic Server 9.1/9.2
