JBoss 7或JBoss EAP 6附带了自己的xalan版本，您可以在其模块中找到它，jboss eap 6.1中的
：

JBoss 7 or JBoss EAP 6 ships with its own xalan version, that you can find among its modules, in jboss eap 6.1:

< JBoss Home> / modules / system / layers / base / org / apache / xalan / main

如果你想先使用你自己的，你必须在 /WEB-INF/jboss-deployment-structure.xml $ c $中使用以下jboss部署描述符排除jboss xalan c> for war和 /META-INF/jboss-deployment-structure.xml for ear：

if you want to use your own first you have to exclude jboss xalan with the below jboss deployment descriptor in /WEB-INF/jboss-deployment-structure.xml for war and /META-INF/jboss-deployment-structure.xml for ear:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <deployment>            
        <exclusions>            
            <module name="org.apache.xalan" />
            <module name="org.apache.xerces" /> 
        </exclusions>
    </deployment>
</jboss-deployment-structure>

我也排除了Xerces，因为它们通常捆绑在一起。

I excluded also Xerces, because usually they are bundled toghether.
