CXF Clustering and Failover feature in EAP

Issue

• We are trying to implement auto fail over and fail back of CXF SOAP calls from a primary to a secondary URL and would like to use the built in CXF failover with a custom circuit switcher written on top of CXF fali over.

JBoss EAP 6 does bundles a version of CXF 2.7.14 a module org.apache.cxf.impl. It seems to be missing jar cxf-rt-features-clustering-2.7.14.jar which allows for auto fail over of SOAP calls from primary to secondary URLs. So we have added a custom module for the feature clustering jar (enclosed) as:

<?xml version="1.0" encoding="UTF-8"?>  
<module xmlns="urn:jboss:module:1.1" name="org.apache.cxf.cxf-rt-features-clustering">  
    <resources>  
        <resource-root path="cxf-rt-features-clustering-2.7.14.jar"></resource>
    </resources>  

    <!--<dependencies>
      <module name="javax.api" ></module> 
    </dependencies>--> 
</module> 

• Also we want to have auto fail back to a primary URL. This is not supported in CXF feature clustering as it only supports fail over. So we also have added another jar cxf-circuit-switcher-1.0.jar to implement a Circuit breaker model with fail back to primary. This module (enclosed) is setup as:

<?xml version="1.0" encoding="UTF-8"?>  
<module xmlns="urn:jboss:module:1.1" name="com.github.jaceko.cxf.cxf-circuit-switcher">  
    <resources>  
        <resource-root path="cxf-circuit-switcher-1.0.jar"></resource>
    </resources>  

    <dependencies>
        <module name="org.apache.cxf" ></module>
        <module name="org.apache.cxf.cxf-rt-features-clustering" ></module>
        <module name="org.slf4j" ></module>
    </dependencies>
</module>  

• The ear we deploy which references these has a jboss-deployment-description.xml file (enclosed) that references the JBoss CXF as well as the circuit switcher.
