ClassCastException in WebLogic 12c

[lost]

I am migrating an app to WebLogic 12c from Glassfish and ran into the below issue. Any help would be greatly appreciated.

I did use Eclipse Link to 2.5 per http://www.docx4java.org/forums/weblogic-f25/how-to-update-to-eclipselink-2-5-in-web-t1574.html. I replaced racle_common\modules\oracle.toplink_12.1.2\eclipselink.jar because deploying it as a Shared Library kept giving me referenced library not found regardless of what I did (and my weblogic.xml and eclipselink ear manifest match)


**EDIT: WL 12c (12.1.2.0.0) actually came with a later Eclipse Link 4.2, which was released on July 4 2013, after 2.5 was released on May 28, 2013.

Please try a nightly build eg http://www.docx4java.org/docx4j/docx4j- ... 130905.jar

Current sources contain a fix for this, not present in docx4j 2.8.1.

Thanks Jason. Got past that error message, but now getting:

I'm not really sure how to proceed with creating sessions.xml to satisfy EclipseLink, even after reading this example http://wiki.eclipse.org/EclipseLink/Examples/MOXy/NativeOxmJaxbContext#Creating_the_Sessions_Configuration_file.

[jason]

Sorry, I was focused on your ClassCastException, and didn't twig that you need the MOXy dependent build.

Please try http://www.docx4java.org/docx4j/docx4j- ... 130909.jar

For Weblogic specific configuration, please see http://stackoverflow.com/questions/1742 ... server-12c

Thanks so much again.

I reverted to EclipseLink 2.4.2.v20130514-5956486 and was able to use docx4j 0905 jar. That was the EclipseLink that came with WL 12c (12.1.2.0.0).

I'll try EclipseLink 2.5 with the docx4j 0909 JAR file.

[julien]

We had the same problem using docx4j with weblogic12. Building a docx4j-Jar using MOXy like described in http://www.docx4java.org/forums/docx-java-f6/moxy-t1242.html solved the ClassCastException Problem, but then other porblems/errors occured (i.e. NPE while processing a word document, although our code worked fine with docx4j-2.8.1 and weblogic 10.3).

However, we found another solution for making docx4j work with weblogic12, also described here: http://docs.oracle.com/middleware/1212/wls/WSGET/jax-ws-datatypes.htm#CIHBHDGI
To summarize: you can configure your application to use the Glassfish RI JAXB Implementation, which was used by weblogic versions prior to 12, by adding 2 configuration files and some lines to weblogic-applicatiion.xml of yout application EAR.

This way, our application works fine using docx4j-2.81.

Thank you Julien for an alternative I'm sure other WebLogic users will find valuable.

but then other porblems/errors occured (i.e. NPE while processing a word document,

Please report such problems (including stack trace) so we can fix them.

MOXy behaves a bit differently to the reference implementation; see for example http://stackoverflow.com/questions/1637 ... -behaviour

As a result, there will be places where docx4j has to take these differences into account
