Jboss EAP 6.4.4 Class Loading problem

[med.amd]

Hello,

I try to deploy a web application on jboss 6.4.4.

The ear file contains Jaxb jars.

When invoking a web service there is a problem with xml binding :

ClassCastException: attempting to cast vfs:/content/App.ear/jaxb-api-2.1.jar/javax/xml/bind/JAXBContext.class

to jar:__file:/home/myworkingfolder/jboss-eap-6.4.4/modules/system/layers/base/javax/xml/bind/api/main/jboss-jaxb-api_2.2_spec-1.0.4.Final-redhat-3.jar!/javax/xml/bind/JAXBContext.class. 

Please make sure that you are specifying the proper ClassLoader.

How to exclude the jboss jaxb lib?

Thanks.

[med.amd]

The jar jboss-jaxb-api_2.2_spec-1.0.4.Final-redhat-3.jar is included within the module "javax.xml.bind.api".

1- I tried in the begining by excluding this module in the jboss-deployment-structure.xml file.

<exclusions>

<module name="javax.xml.bind.api"/>

</exclusions>

The module was not excluded even with this explicit exclusion.

This module was loaded implicitly by the javaee module.

2- So I tried to exclude the javaee module and put its module.xml content within the jboss-deployment-structure.xml without the javax.xml.bind.api module

<exclusions>

<module name="javaee.api"/>

</exclusions>

<dependencies>

<module name="javax.activation.api" export="true"/>

<module name="javax.annotation.api" export="true"/>

<module name="javax.ejb.api" export="true"/>

<module name="javax.el.api" export="true"/>

<module name="javax.enterprise.api" export="true"/>

<module name="javax.enterprise.deploy.api" export="true"/>

<module name="javax.inject.api" export="true"/>

<module name="javax.interceptor.api" export="true"/>

<module name="javax.jms.api" export="true"/>

<module name="javax.jws.api" export="true"/>

<module name="javax.mail.api" export="true"/>

<module name="javax.management.j2ee.api" export="true"/>

<module name="javax.persistence.api" export="true"/>

<module name="javax.resource.api" export="true"/>

<module name="javax.rmi.api" export="true"/>

<module name="javax.security.auth.message.api" export="true"/>

<module name="javax.security.jacc.api" export="true"/>

<module name="javax.servlet.api" export="true"/>

<module name="javax.servlet.jsp.api" export="true"/>

<module name="javax.transaction.api" export="true"/>

<module name="javax.validation.api" export="true"/>

<module name="javax.ws.rs.api" export="true"  services="export"/>

<!-- <module name="javax.xml.bind.api" export="true"/> -->

<module name="javax.xml.registry.api" export="true"/>

<module name="javax.xml.soap.api" export="true"/>

<module name="javax.xml.ws.api" export="true"/>

<!-- This one always goes last. -->

<module name="javax.api" export="true"/>

<dependencies>

This method exclude the javax.xml.bind.api.

But I encoutered this error :

Caused by: java.lang.NoClassDefFoundError: org/apache/cxf/frontend/ClientProxy

I resolved this error by adding cxf in the dependencies:

<module name="org.jboss.ws.cxf.jbossws-cxf-client" services="import" />

<module name="org.apache.cxf.impl">

    <imports>

        <include path="META-INF"/>

        <include path="META-INF/cxf"/>

    </imports>

</module>

The jboss-deployment-structure.xml become very verbose...
