This problem is probably because you don't have a xalan library in your project.

So, either you can add it to the project from http://mvnrepository.com/artifact/xalan/xalan/2.7.2 or you can use the one which is included in the JBoss server by creating a jboss-deployment-structure.xml file:

<jboss-deployment-structure>
    <deployment>            
        <exclusions>            
            <module name="org.apache.xalan" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

In case you have any problems - add xerces library as well:

<jboss-deployment-structure>
    <deployment>            
        <exclusions>            
            <module name="org.apache.xalan" />
            <module name="org.apache.xerces" /> 
        </dependencies>
    </deployment>
</jboss-deployment-structure>

Hope this helps.
