9:42 a.m.
Hello.
I have a remote server and a client in the form of an MBean, designed following the
Serialization Server example from JBoss Remoting.
The Server
| import javax.management.MBeanServer;
|
| import org.jboss.remoting.InvocationRequest;
| import org.jboss.remoting.InvokerLocator;
| import org.jboss.remoting.ServerInvocationHandler;
| import org.jboss.remoting.ServerInvoker;
| import org.jboss.remoting.callback.InvokerCallbackHandler;
| import org.jboss.remoting.transport.Connector;
|
| import ro.ebsoft.doorcontrol.comm.common.CommModuleMain;
| import ro.ebsoft.doorcontrol.interfaces.CommModule;
|
| public class Main {
|
| private static String transport = "rmi";
| private static String host = "localhost";
| private static int port = 5400;
|
| private static CommModule response;
|
| public void setupServer(String locatorURI) throws Exception {
| InvokerLocator locator = new InvokerLocator(locatorURI);
| System.out.println("Starting remoting server with locator URI of: "
| + locatorURI);
| Connector connector = new Connector(locator);
|
| connector.create();
|
| SampleInvocationHandler invocationHandler = new SampleInvocationHandler();
| connector.addInvocationHandler("CommModule", invocationHandler);
|
| connector.start();
| }
|
| // rmi server main class
| public static void main(String args[]) {
|
| String locatorURI = transport + "://" + host + ":" + port
| + "/?serializationtype=jboss";
| Main main = new Main();
|
| try {
| response = new CommModuleMain();
| main.setupServer(locatorURI);
| while (true) {
| Thread.sleep(1000);
| }
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
|
| public static class SampleInvocationHandler implements
| ServerInvocationHandler {
|
| @Override
| public void addListener(InvokerCallbackHandler arg0) {
| }
|
| @Override
| public Object invoke(InvocationRequest invocation) throws Throwable {
| System.out.println("Invocation request is "
| + invocation.getParameter());
|
| return new CommModuleMain();
| }
|
| @Override
| public void removeListener(InvokerCallbackHandler arg0) {
| }
|
| @Override
| public void setInvoker(ServerInvoker arg0) {
| }
|
| @Override
| public void setMBeanServer(MBeanServer arg0) {
| }
|
| }
| }
|
The MBean class
| package ro.ebsoft.doorcontrol.mbean.engine;
|
| import org.jboss.remoting.Client;
| import org.jboss.remoting.InvokerLocator;
| import org.jboss.system.ServiceMBeanSupport;
|
| import interfaces.CommModule;
|
| public class CommEngine extends ServiceMBeanSupport implements CommEngineMBean {
|
| private static String transport = "rmi";
| private static String host = "localhost";
| private static int port = 5400;
|
| public String getMessage() {
| return message;
| }
|
| public void setMessage(String message) {
| this.message = message;
| }
|
| public void printMessage(){
| log.info(message);
| }
|
| protected void startService() throws Exception{
| log.info("Starting CommModuleMBean");
| String locatorURI = transport + "://" + host + ":" + port +
"/?serializationtype=jboss";
| log.info("Connecting to " + locatorURI);
| //String locatorURI = transport + "://" + host + ":" + port;
|
| InvokerLocator locator = new InvokerLocator(locatorURI);
| Client remotingClient = new Client(locator);
| remotingClient.connect();
|
| try{
| CommModule cm = (CommModule)remotingClient.invoke("CommModule");
| }
| catch(Throwable t){
| t.printStackTrace();
| }
| }
|
| protected void stopService() throws Exception{
| log.info("Stopping with message: " + message);
| }
|
| //setters & getters
| }
|
When I run both the server and a similar client (which is not an MBean), all goes well.
But when I deploy my client as a .sar in the app server, I get
| ERROR [MainDeployer] Could not create deployment:

I have included a .jar which contains interfaces.CommModule in the MBean .sar.
If I change the server to return. say, a String rather than a CommModule, all goes well,
the MBean deploys and works as expected (obtains the string by invoking the remote
server).
All I want to do is to obtain a remote instance of a CommModule when the app server
starts.
Could someone explain what am I doing wrong? Or a better idea (any idea) of doing this?
Thank you for your time.
