POSerializationProblem (?) of custom AsyncCallback
text
Body
copied!<p>I implemented an own Marshalling/Unmarshalling Sytem with JMS (exercise). I do Request and get Responses back. I want to fire an own callback in response after i received the correct response. But i think my exception is a serialization problem. But i don't know how to fix it.</p> <p>I use that code to call a server</p> <pre><code>button.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { Request request = new Request("printServer:" + printMessage.getText()); request.setAsyncCallback(new AsyncCallback() { /** * */ private static final long serialVersionUID = 5204649755139243369L; @Override public void onSuccess(String content) { System.out.println("async callback: " + content); } }); c.callServer(request); } }); </code></pre> <p>My request looks like this:</p> <p>public class Request extends Conveyable { private static final long serialVersionUID = 4535036450648916878L;</p> <pre><code>public static int requestIDInc = 0; private int requestID; private AsyncCallback callback; public Request(String content) { super(content); synchronized (this) { requestID = ++requestIDInc; } } public int getRequestID() { return requestID; } public AsyncCallback getAsyncCallback() { // TODO Auto-generated method stub return callback; } public void setAsyncCallback(AsyncCallback callback) { this.callback = callback; } </code></pre> <p>}</p> <p>My own Callback looks like this:</p> <pre><code>public abstract class AsyncCallback implements Serializable{ /** * */ private static final long serialVersionUID = 4951246599084406476L; public abstract void onSuccess(String content); </code></pre> <p>}</p> <p>And the exception i got is this:</p> <pre><code>javax.jms.MessageFormatException: machines.client.ClientWindow$1 at org.exolab.jms.message.ObjectMessageImpl.setObject(ObjectMessageImpl.java:194) </code></pre> <p>It looks a little bit as if the ClientWindow in which a create the Request and fire it off with a buttonClick is included in this callback. But i don't know why. Or maybe the problem isn't there.</p>
