Seems like I am following the spec correctly and JAX-RPC is generating the exception class correctly (I think), but I still cannot get this to work. I am wondering if there is something configuration wise that I need to setup in JBoss to get the correct exception back on the client side. I have a user defined exception: | <xsd:element name="TestExceptionElement" type="xsd:string"/> | | <message name="TestException"&gt; | <part name="message" type="TestExceptionElement"/> | </message> | . | . | <operation name="throwTestException"> | <input message="tns:throwTestException_request"/> | <output message="tns:throwTestException_response"/> | <fault name="TestException" message="tns:TestException"/> | </operation> | This generates the following code for the exception: | public class TestException extends java.lang.Exception { | private java.lang.String message; | | public TestException(java.lang.String message) { | super(message); | this.message = message; | } | | public String getMessage() { | return message; | } | } | When I throw this exception on the server side things look ok. However on the client side I catch a SOAPFaultException instead of my TestException. Has anyone successfully defined an exception and caught that exception on the client side?
