ClassCastException using CXF 2.7.0 JAX-RS Client in JBoss AS7

[mathewvino]

I have trouble with CXF 2.7.0 in a JBoss AS7 environment. There is a classpath conflict with the RESTEasy Response class:

Caused by: java.lang.ClassCastException: org.jboss.resteasy.core.ServerResponse cannot be cast to org.apache.cxf.jaxrs.impl.ResponseImpl at org.apache.cxf.jaxrs.client.WebClient.handleResponse(WebClient.java:975) ... 

Google around and added the following configuration in jboss_deployement_structure.xml file. But no luck I am using jboss7.1.1 as my application server. Any thoughts on this. Thanks for the help

<sub-deployment name="tfnmgr.war">

            <exclusions>

             <module name="org.jboss.resteasy.resteasy-atom-provider"/>

            <module name="org.jboss.resteasy.resteasy-cdi"/>

                    </exclusions>

You need to disable the same like this,

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
  <deployment>
    <exclude-subsystems>
      <subsystem name="jaxrs" />
      <subsystem name="webservices" />
    </exclude-subsystems>
  </deployment>
</jboss-deployment-structure>

Thanks Viral for the quick response. I tried with this but the problem is I am using JBOSS7.1.1 and i am getting like the following error

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[2,1]

Message: Unexpected element '{urn:jboss:deployment-structure:1.2}jboss-deployment-structure'.

Is it something like I need to upgrade my jboss to the latest version.

Thanks for the help

Hi Vinod,

This depends on the namespaces configured in module.xml for jax-rs and cxf.

For example, in $JBOSS_HOME/modules/org/apache/cxf/main/module.xml, the xmlns points to  'urn:jboss:module:1.1', then you would need to have the same in your jboss-deployment-structure.xml.

Like this, <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">.

Can you please try this out and let me know the results ?

Thanks Viral,

I think I tried  and I am getting the following error .The error says <exclude-subsystems> is not supported in 7.1.1

Are you get that exception when the application is deployed or invoking it ?

and

<!--

        <extension module="org.jboss.as.jaxrs"/>-->

in standalone.xml

Hi Mathew,

I have a war and use cxf 2.7.5 and Jboss 7.1.1.Final. That works with jboss-deployment-structure.xml in my web-inf :

                              <!-- Exclude JAVA EE of JBOSS (javax.ws..) => Add dependency javax.annotation -->

                              <module name="javaee.api" />
