Tom thanks for your reply.
After I added a ServerCallBackHandler on the server side, the ClassNotFoundException was gone.
I changed the code as per your suggestion, to create a Connector on the client to receive a push call. However the following code gets executed on the jboss server itself, which is where my remoting server resides as service.
public void pingClients() {
| if (m_listeners.size() > 0) {
| Object data = "ping";
| Callback c = new Callback(data);
| Set<InvokerCallbackHandler> errorSet = new HashSet<InvokerCallbackHandler>();
| for (InvokerCallbackHandler h : m_listeners) {
| try {
| h.handleCallback(c);
| } catch (HandleCallbackException e) {
| errorSet.add(h);
| }
| }
| logger.info("Failed ping for " + errorSet.size() + " clients...");
| for (InvokerCallbackHandler h : errorSet) {
| m_listeners.remove(h);
| }
| }
| }
|
The client never receives the ping message. Consequently once the client is added and exits without removing Listener from the server, I don't know how to remove it from the list of listeners.
Here is my client call back handler:
public class ClientCallbackHandler implements InvokerCallbackHandler, Serializable {
|
| public void handleCallback(Callback callback) throws HandleCallbackException {
| Object obj = callback.getParameter();
| System.out.println("The server sent: "+obj);
| }
|
| }
|
The client is able to call invoke of the server. This works fine, however in my code I create client connector and register the client handler based on the return value from this invoke (for push callback).
| int i = (Integer) client.invoke("acquire");
| if (i >= 0) {
| String callbackLocatorURI = transport + "://" + serverName + ":" + (port + 1);
| InvokerLocator callbackLocator = new InvokerLocator(callbackLocatorURI);
| setupServer(callbackLocator);
| client.addListener(handler, locator);
| }
|
appreciate your help.
regards,
vivek
