Catching webservice exception with CXF: NoClassDefFoundError: SOAPFaultBuilder

Question

I've been using Apache CXF wsdl2java generated code to call methods from a webservice for some time now, which so far has been working fine.. The problem I'm having is that when the webservice (implemented just down the hall from me) legitimately throws a soap exception, CXF comes up with the following Error message:

Could not initialize class com.sun.xml.internal.ws.fault.SOAPFaultBuilder

I'm using Ubuntu 9.04, OpenJDK (IcedTea6 1.4.1) 6b14-1.1.1-0ubuntu11, Maven2 and CXF 2.2.3. I'm currently at a loss about how to resolve this problem, as the code and setup I'm using seems trivially simple.. Anyone able to point me in the right direction here? Let me know if I can post any further details..

This is the full stacktrace returned:

Answer 1

Had similar problem when we're switching from Ant to Maven. We use Sun JDK 1.6u20.

We've missed these libraries in maven-assembled war's:

jaxws-api jaxws-rt jaxws-tools

After adding them all works as it had worked before. Hope this will help someone!

Answer 2

There are two interesting things about that stack trace:

1) It is having problems finding an SAAJ implementation. Probably adding saaj-impl.jar to the classpath might resolve that.

2) It's not using CXF at all. It's using the Sun JAX-WS reference implementation that's built into the jre. Thus, it looks like the cxf jars aren't being picked up at all.
