I am experimenting with writing my own fault handler. I have a simple
HelloWorld service with a method that throws an exception. I created a
class called MyFaultListener which implements SOAPFaultListener. For now,
the fault() method code is identical to that in DOMFaultListener.
If I deploy the service with either of Apache's basic fault handlers
(DOMFaultListener or ExceptionFaultListener), it works fine. If I deploy
with my fault handler, Tomcat throws the following exception:
java.lang.NoClassDefFoundError: org/apache/soap/server/SOAPFaultListener
It seems like a classpath problem, but why would it be able to find
SOAPFaultListener if the fault handler is DOMFaultListener but not
MyFaultListener? They are identical except for the class name. In fact, I
can deploy with all three fault handlers in the deployment descriptor, and
it blows up only when trying to load MyFaultListener (I added debug code to
SOAPContext.java).
I am using Tomcat version 3.3-m3, and soap.jar is in TOMCAT_HOME\lib\apps
directory.
Any insight would be appreciated.
Thanks!
