JBOSS issues

[hugopais]

Hi everyone,

I'm currently starting to use docx4j and i'm having trouble when loading any docx document. I'm using JBOSS and the error it gives is the following:

2009-07-13 18:56:21,577 INFO [org.docx4j.openpackaging.parts.Part] Constructing /_rels/.rels

Any ideas on what is happening?

Thanks in advance

Which version of JAXB are you using?

Problem is likely to be to do with whether JBOSS is using its own copies of JAXB, rather than yours.

Maybe http://bimalesh.blogspot.com/2007/05/jb ... dk-16.html helps?

Thanks for the help.

It was in fact JBOSS loading a wrong version of JAXB (2.0.3).

After solving this one i end up getting a new one a little more tricky. Apparently JBOSS uses a different classloader to load JAXBContext and the only way to solve it was to explicity indicate which classloader it should use:

Context.jc = JAXBContext.newInstance("org.docx4j.wml:org.docx4j.dml",this.getClass().getClassLoader());
Context.jcThemePart = JAXBContext.newInstance("org.docx4j.dml",this.getClass().getClassLoader());
Context.jcDocPropsCore = JAXBContext.newInstance("org.docx4j.docProps.core:org.docx4j.docProps.core.dc.elements:org.docx4j.docProps.core.dc.terms",this.getClass().getClassLoader());
Context.jcDocPropsCustom = JAXBContext.newInstance("org.docx4j.docProps.custom",this.getClass().getClassLoader());
Context.jcDocPropsExtended = JAXBContext.newInstance("org.docx4j.docProps.extended",this.getClass().getClassLoader());
Context.jcXmlPackage = JAXBContext.newInstance("org.docx4j.xmlPackage",this.getClass().getClassLoader());
Context.jcRelationships = JAXBContext.newInstance("org.docx4j.relationships",this.getClass().getClassLoader());

Thanks for this; will be useful for anyone else using docx4j with JBOSS.

I guess Context.java should be changed so it works with JBOSS out of the box. I'll test to see whether this.getClass().getClassLoader() causes any issues with Tomcat first.

Hi Hugo,

Can you show how you implemented that change in the code? In the base version those statements are inside a static block, so I was wondering how you were able to sneak in the "this" reference.

Thank You,

Hi,

I am still looking into how to use this.getClass().getClassLoader() with the JAXBContext. So if anyone has any ideas, feel free to chime in.

Cheers

See revision 894. I don't think all versions of JBOSS are affected, but this fix doesn't distinguish between environments at all (JBOSS or otherwise).

It appears to be version specific - I'm working with JBoss 4.2.1.GA and have not encountered either of these problems.
