WebLogic: javax.xml.namespace.QName; local class incompatible

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

  • I do not know how to implement any of the above workaround.
    I get the same error when click on start -> program -> BEA products -> User Projects -> userdomainname -> Start Admin Server for Weblogic Server Domain.

    I tried to modify the %SystemRoot%\system32\cmd.exe /k”C:\bea\user_projects\domains\userdomainname\bin\startWebLogic.cmd”
    , but that did not help.

    Please advise.
    Thanks

    Do you have the very same situation? i.e. JRockit 1.5.0_07 version (and later) used with WebLogic Server 9.1 or 9.2? If yes, what modification did you make? And when your server started, did you check the arguments of the running JVM to confirm your change?
