Hi there, I'm trying to make a simple hallo World with a parameter and a custom exception that has its own field. Without the extra field in the exception it works fine. Server start up fine but when I call my webservice with the field "naam" filled in with "kaboom" (with this value the exception is thrown) this is what I get: 08:48:41,921 ERROR [RequestHandlerImpl] Error processing web service request org.jboss.ws.WSException: org.jboss.xb.binding.JBossXBRuntimeException: Failed to find read method or field for property 'typeFout' in class nl.havermans.rhcp.boodschappen.webservice.EWebserviceException at org.jboss.ws.WSException.rethrow(WSException.java:68) at org.jboss.wsf.stack.jbws.RequestHandlerImpl.handleRequest(RequestHandlerImpl .java:310) at org.jboss.wsf.stack.jbws.RequestHandlerImpl.doPost(RequestHandlerImpl.java:1 89) at org.jboss.wsf.stack.jbws.RequestHandlerImpl.handleHttpRequest(RequestHandler Impl.java:122) at org.jboss.wsf.stack.jbws.EndpointServlet.service(EndpointServlet.java:84) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) The problem is that the property really is in the class nl.havermans.rhcp.boodschappen.webservice.EWebserviceException, I even tried to make the field itself public but it doesn't help. Does anyone know why this is happening? I have provided the source files so you can have a look at it (deleted the libs for size issues). Can anyone have a look at this? Kind regards, Ramon Havermans
