 Is there a way to use CXF with its own classloader which has own versions of
 Jars ?

I came across this project yesterday, would this help?

CXF with own Classloader

[ladidaaa]

Hello, 

i am facing the  following problem: 

I am using a closed source legacy application ( kind of application server )
which uses AXIS 1 as webservice engine. 

I have the possibility to extend the applications running on the
applicationserver through a progamming interface. In this extensions i am
trying to use CXF, but this won't work this easy because , both Axis1 and
CXF need the wsdl4j.jar but in different versions. 

Is there a way to use a own classloader ?  I tried to create a dynamic
client with my own newly created URLClassloader which didn't work 

JaxWsDynamicClientFactory jwdcf =  JaxWsDynamicClientFactory.newInstance();
Client client = jwdcf.createClient(URL,urlCl);

As the second approache i tried to create CXF through the classloader like
this : 

ClassJaxWsDynamicClientFactory c =(ClassJaxWsDynamicClientFactory)
urlCl.loadClass(org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory);
c.newInstance();

which failed with a instatiation exception. 

Is there a way to use CXF with its own classloader which has own versions of
Jars ?

You could try and use the FirewallClassLoader @
org.apache.cxf.common.classloader.FirewallClassLoader

There is a JUnit test that shows how to use it
herehttp://svn.apache.org/repos/asf/cxf/trunk/common/common/src/test/java/org/apache/cxf/common/classloader/FireWallClassLoaderTest.java
