Dom4J problems on jboss 7 with maven

[haukegulich]

Dear users,

I am kind of frustrated because I just want to deploy my maven project on jboss 7. In my application I am using

Dom4J for parsing a xml file.

If I am executing that method by itsself within eclipse, it is working. If I am deploying this application if gives me an

I am using maven and my pom.xml looks like this:

I set up dom4j as provided because if I remove to scope line at dom4j, jboss can not parse my hibernate.cfg.xml file anymore. I read something about

that issue and it seems to occure if there are version conflicts between dom4j.

I also checked in eclipse via "effective pom" if dom4j will be included from another dependency.

I also tried to upload the dom4j.jar at the jboss administrative panel and activate that deployment, but with the same result.

Does anyone has an idee? Do you need more informations?

Thanks,

Hauke

You have to declare an explicit dependency on the org.dom4j contained in AS7 if you declared it as provided. You can choose between adding  a jboss-deployment-structure.xml descriptor or a Dependencies: entry in the manifest.

See https://docs.jboss.org/author/display/AS71/Developer+Guide#DeveloperGuide-CreateormodifyfilesthatcontrolclassloadinginAS7 for relevant documentation.

A solution (that does not require additional files in WAR/EAR) would be adding

<subsystem xmlns="urn:jboss:domain:ee:1.1">

    <global-modules>

        <module name="org.dom4j" />

    </global-modules>

</subsystem>

in your standalone.xml/domain.xml file, as explained in http://www.javacodegeeks.com/2012/09/jboss-as-7-classloading-explained.html at section "Setting up global modules".

This helped me because i was already declaring dom4j as provided, and didnt want to include AS-specific files in my JAR/WAR/EAR to keep them as clean as possible.
