how to work jboss with docx4j library.

[lakshani]

I try to generate a pptx using pptx4j library. I could generate a pptx successfully. Then I applied the code to a huge project that run on the jboss 7 server. Project is sucessfully deployed on the server. But when I'm trying to run the application it gives following exception. 

java.lang.NoClassDefFoundError: com/sun/xml/internal/bind/marshaller/NamespacePrefixMapper

That exception is occurred for following line in the code.

PresentationMLPackage presentationMLPackage = PresentationMLPackage .createPackage(); 

Is there a special way run docx4j library on the jboss 7 server.

Judging from the information you provided, it looks like docx4j library is using a JDK internal library. I would avoid those kind of libraries because they will break in JDK 9 when Jigsaw is implemented.

I think the reason why it is failing on JBoss 7 is that it is running a JRE that is 6u17 or older whereas your box is running one that is newer. The namespace of that class in the JRE changed after 6u17. Therefore, that particular version of docx4j can only run on JRE's that is 6u18 and older.

I would recommend switching to Apache Poi for pptx if possible. Docx4j will give you problems in the future.
