How to replace EclipseLink 2.3.2 with EclipseLink 2.5 in WebLogic Server 12c - eclipselink

Question

I currrently try to run Docx4j in WebLogic Server 12c. WebLogic Server 12c comes with EclipseLink 2.3.2.
There is a similar Post describing the situation which unfortunately yield no answer.
Docx4j does not work with the JAXB (MOXy) implementation which is part of EclipseLink 2.3.2. I got Docx4j running standalone with EclipseLink 2.5. So I am very confident that using EclipseLink 2.5 with Weblogic Server 12c will solve the issue with Docx4j.
How can I replace the EclipseLink Vesion 2.3.2 the WebLogic Server 12c is running on with EclipseLink Version 2.5?

Answer 1

You can created a shared library in WebLogic to update the version of EclipseLink.
CREATE THE SHARED LIBRARY
EclipseLink25_SharedLibrary.ear
The shared library is an EAR with the following contents
lib/eclipselink.jar
META-INF/application.xml
<application>
<display-name>EclipseLink 2.5 Shared Library</display-name>
<module>
<java></java>
</module>
</application>
META-INF/MANIFEST.MF
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.2
Created-By: 1.7.0_04-b21 (Oracle Corporation)
Extension-Name: EclipseLink-2.5.0
Specification-Version: 2.5.0
Implementation-Version: 2.5.0.v20130507
META-INF/weblogic-application.xml
<weblogic-application>
<prefer-application-packages>
<package-name>org.eclipse.persistence.*</package-name>
</prefer-application-packages>
</weblogic-application>
USE THE SHARED LIBRARY
Belowis how you would package your application to use the shared library,
SampleApplication.ear
META-INF/MANIFEST.MF
META-INF/weblogic-application.xml
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-application xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-application" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/javaee_5.xsd http://xmlns.oracle.com/weblogic/weblogic-application http://xmlns.oracle.com/weblogic/weblogic-application/1.2/weblogic-application.xsd">
<!--weblogic-version:10.3.4-->
<wls:application-param>
<wls:param-name>webapp.encoding.default</wls:param-name>
<wls:param-value>UTF-8</wls:param-value>
</wls:application-param>
<wls:library-ref>
<wls:library-name>EclipseLink-2.5.0</wls:library-name>
<wls:specification-version>2.5.0</wls:specification-version>
<wls:implementation-version>2.5.0.v20130507</wls:implementation-version>
<wls:exact-match>true</wls:exact-match>
</wls:library-ref>
</wls:weblogic-application>

Answer 2

The solution provided by Blaise in his Blogpost does not work with WebLogic 12c. The solution to get it working is a minor change to the application.xml by explicitly defining the used library:
<application>
<display-name>EclipseLink 2.5 Shared Library</display-name>
<module>
<java>lib/eclipselink.jar</java>
</module>
</application>

I prefered to switch back to the JAXB RI instead of using the buggy moxy JAXB.
Here is how you can do it:
http://docs.oracle.com/cd/E24329_01/web.1211/e24964/data_types.htm#CIHBHDGI
I used the Methode where the following jar module file is put in the "startWebLogic.cmd":
set PRE_CLASSPATH=$wls_home/modules/databinding.override_1.0.0.0.jar
to have it first in the classpath.
