weblogic.descriptor.DescriptorException: Unmarshaller failed

Question

When i deploy my WAR in Weblogic 10.3.6 it runs but in weblogic 10.3.0 it throws this:

Unable to load descriptor D:\bea103\user_projects\domains\SRVWinplex\Deployments\WinplexAdmin.war/WEB-INF/weblogic.xml of module WinplexAdmin.war. The error is weblogic.descriptor.DescriptorException: Unmarshaller failed at weblogic.descriptor.internal.MarshallerFactory$1.createDescriptor(MarshallerFactory.java:152) at weblogic.descriptor.BasicDescriptorManager.createDescriptor(BasicDescriptorManager.java:306) at weblogic.application.descriptor.AbstractDescriptorLoader2.getDescriptorBeanFromReader(AbstractDescriptorLoader2.java:788) at weblogic.application.descriptor.AbstractDescriptorLoader2.createDescriptorBean(AbstractDescriptorLoader2.java:409) at weblogic.application.descriptor.AbstractDescriptorLoader2.loadDescriptorBeanWithoutPlan(AbstractDescriptorLoader2.java:759) at weblogic.application.descriptor.AbstractDescriptorLoader2.loadDescriptorBean(AbstractDescriptorLoader2.java:768) at weblogic.servlet.internal.WebAppDescriptor.getWeblogicWebAppBean(WebAppDescriptor.java:170)

It's a problem with the weblogic.xml i guess. This is my weblogic.xml(Without basic tags) :

<jsp-descriptor>
    <keepgenerated>true</keepgenerated>
    <debug>true</debug>
</jsp-descriptor>
<context-root>/WinplexAdmin</context-root>
<library-ref>
    <library-name>jsf</library-name>
    <specification-version>2.0</specification-version>
    <implementation-version>1.0.0.0_2-0-2</implementation-version>
</library-ref>
<container-descriptor>
    <prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

What can be the problem here ?

Solved. I was compiling with a newer weblogic.jar I mean: I had Weblogic 10.3.6 attached to NetBeans, so it was a different weblogic.xml.

A correct weblogic.xml for Weblogic 10.3.0 is like this:

<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/weblogic-web-app http://www.bea.com/ns/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">

You can see "http://www.bea.com/" in the xml while a weblogic.xml for Weblogic 11g and etc. has links with "java" or "sun" in it.

I just downloaded Weblogic 10.3.0, attached it to NetBeans, change the server for the project from Weblogic 10.3.6 to 10.3.0 and then re-compile.

Or... the easy way is just replacing the weblogic.xml code for the one i pasted here and compile.

I hope it solves your problem.
