CXFServlet, extensions and classloader issues
Hi,
When CXF loads, from what I understand, it scas that classpath for
extensions. Is there a way to control extension loading?
The reason I want to do this is because I want to use CXF 2.2.6 in the
Geronimo 2.2 app server. Geronimo already includes CXF 2.1.4. Therefore,
in a geronimo-specific deployment descriptor (geronimo-web.xml) I "hide"
the geronimo-bundled CXF so that the one from WEB-INF/lib is used. This
is done by specifying the following in geronimo-web.xml:
<sys:hidden-classes>
<sys:filter>org.springframework</sys:filter>
<sys:filter>org.apache.cxf</sys:filter>
</sys:hidden-classes>
Unfortunalely, there's a geronimo extension to CXF (see
http://repo2.maven.org/maven2/org/apache/geronimo/modules/geronimo-cxf/2.2/geronimo-cxf-2.2.pom)
that gets detected (via the META-INF/cxf/cxf-extension-geronimo.xml) and
CXF tries to load it. Ultimately this ends up in invoking code loaded
from Geronimo's class loader that is linked against Geronimo's CXF
(2.1.4) and causes class definition mismatches (see stacck trace at end
of this e-mail).
So, is there a way to tell CXF to ignore a specific extension while
scanning its classpath?
Here's the stack trace I get:

You may be able to try adding a filter of META-INF.cxf or something to filter
out that stuff as well. I'm really not sure if that works or not.
In general, the best option in this case would be to create your own Sprint
context definition that imports the things from CXF that you need directly
which would avoid the scan entirely.
