Hi, I have an ejb which is exposed over a webservice. The methods on the ejb that have no chance of throwing exceptions work fine. As soon as I put in a new method which can throw an application exception (and generate is as a web method) none of my methods work over web services... i get this error: Exception in thread "main" java.rmi.RemoteException: Call invocation failed with code [Client] because of: javax.xml.rpc.JAXRPCException: Cannot create or send response message; nested exception is: javax.xml.rpc.soap.SOAPFaultException: javax.xml.rpc.JAXRPCException: Cannot create or send response message at org.jboss.ws.jaxrpc.CallImpl.invokeInternal(CallImpl.java:715) at org.jboss.ws.jaxrpc.CallImpl.invoke(CallImpl.java:398) ....(then the class where the method gets invoked) I've tried various techniques -even wrapping the exception in a remoteException just to see if i could get it working. Any ideas what i might be doing wrong? Thanks. CODE: ----------------- My Bean: //Annotations left out public class MMAPIBean implements MMAPI { public GetEchoResult getEcho(String echo){ GetEchoResult ge = new GetEchoResult(); ge.setEchoInString(echo); return ge; } public ReferenceTypeResult getStatusCodes() throws RemoteException { try { ReferenceTypes rt = new ReferenceTypes(); return rt.getStatusCodes(); } catch (MMAPIException e) { throw new RemoteException(e.getMessage()); } } } ------------ Remote and local interface: @Local @Remote public interface MMAPI { public GetEchoResult getEcho(String echo); public ReferenceTypeResult getStatusCodes() throws RemoteException; } ---------------- Service endpoint: // Annotations left out public interface MMAPIsei extends Remote { @WebMethod public GetEchoResult getEcho(String echo) throws RemoteException; @WebMethod public ReferenceTypeResult getStatusCodes() throws RemoteException; } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977870#...
