Argh. I thought I replied to this weeks ago. Trying again, as I still need
help to get away from using RPC/encoded and use RPC/literal instead.
Service Endpoint interface:
| package com.mycompany.tws;
|
| import java.rmi.Remote;
| import java.rmi.RemoteException;
| import com.mycompany.enterprise.document.DocumentAccessException;
| import com.mycompany.tws.document.DocumentBean;
|
| public interface DocumentJse extends Remote {
| public String storeDocument(DocumentBean docBean) throws
RemoteException, DocumentAccessException;
| }
|
Service endpoint implementation:
| package com.mycompany.tws;
|
| import java.rmi.RemoteException;
| import javax.xml.rpc.ServiceException;
| import javax.xml.rpc.server.ServiceLifecycle;
| import com.mycompany.enterprise.document.DocumentAccessException;
| import com.mycompany.tws.document.DocumentBean;
|
| public class DocumentJseImpl implements DocumentJse, ServiceLifecycle {
|
| private static final boolean FORCE_EXCEPTION = false;
|
| public DocumentJseImpl() {}
| public void init(Object arg0) throws ServiceException {}
| public void destroy() {}
|
| public String storeDocument(DocumentBean docBean) throws
RemoteException, DocumentAccessException {
| System.out.println("DocumentJseImpl.storeDocument");
| if (FORCE_EXCEPTION) {
| System.out.println(" Throwing access exception.");
| throw new DocumentAccessException();
| }
| String[] docVals = docBean.getVals();
| for (int i=0; i<docVals.length; i++) {
| System.out.println(" docVals[" + i + "] = " + docVals);
| }
| return "Happy day.";
| }
| }
|
DocumentBean transport object:
| package com.mycompany.tws.document;
|
| public final class DocumentBean {
| private String [] vals;
| public DocumentBean() {}
| public DocumentBean(String [] vals) { this.vals = vals; }
| public String [] getVals() { return vals; }
| public void setVals(String [] vals) { this.vals = vals; }
| }
|
On the client side, we're doing things a bit strange with regard to registering
serializers for the transport objects. I know there is a JBoss specific
implementation of ServiceFactory that takes a pointer to the JAX-RPC mapping
file so that you don't have to manually register all the bean serializers and
deserializers, but we need this client to work with web services deployed on
WebLogic as well as on JBoss. Here's the code on the client-side
