Please help with writing EJB 3.0 Service. I can't get it to deploy.
I wrote the following EJB 3.0 Service:
| @Service(objectName = "ejb3:service=PollingService")
| @Management(PollingServiceManagement.class)
| public class PollingService implements PollingServiceManagement {
|
| Thread pollingThread = null;
| int pollingInterval = 30;
| boolean destroy;
|
| public int getPollInterval() {
| // TODO Auto-generated method stub
| return pollingInterval;
| }
|
| public void setPollInterval(int pollingInterval) {
| this.pollingInterval = pollingInterval;
| }
|
| // Lifecycle methods
| public void create() throws Exception {
| System.out.println("PollingService - Creating");
| pollingThread = new PollingThread();
| pollingThread.start();
| }
|
| public void destroy() {
| System.out.println("PollingService - Destroying");
| destroy = true;
| if(pollingThread != null && pollingThread.isAlive())
| pollingThread.interrupt();
| }
|
| public class PollingThread extends Thread {
| @Override
| public void run() {
| while(!destroy){
| try{
| sleep(pollingInterval*1000);
| System.out.println("Starting Poll...");
| }catch(InterruptedException ex){
| System.out.println("PollingThread
interrupted: "+ex.getMessage());
| }
| }
| }
| }
| }
|
I could not get it to deploy without the jboss-service.xml. So I created one to
describe the MBean:
| <?xml version="1.0" encoding="UTF-8"?>
| <server>
| <mbean code="org.vss.jboss.service.PollingService"
| name="ejb3:service=PollingService">
| </mbean>
| </server>
|
I am getting the following error while trying to deploy a Service "sar" file.
