[EJB 3.0] - SessionContext and TimerService
by go_rags
Hi,
I am using JBossAS 4.0.3 SP1 in our product and recently tried to add a timer service to it. I am having problem retrieving the session context for writing a Timer Service. I am getting a NULL value injected for both the TimerService and SessionContext, is there a way to work around it.
I am invoking the startPolling() method on startup from a servlet.
|
| @Stateless
| @Remote(IRSSPoller.class)
| public class RSSPoller implements IRSSPoller {
|
| private @Resource
| SessionContext ctx;
|
| private @Resource
| TimerService tms;
|
| private @PersistenceContext
| EntityManager _entityManager;
|
|
| public void startPolling() {
|
| if (ctx == null) System.err.println("SessionContext is NULL!!");
| if (tms == null) System.err.println("TimerService is NULL!!");
|
| if (ctx != null) {
| ctx.getTimerService().createTimer(new Date(),
| milliseconds, com.nukore.hub.rss.RSSPoller.class);
| }
| }
|
| @Timeout
| public void timeoutHandler(Timer timer) {
|
| //Timer Method....
|
| }
|
| }
|
|
Thanks in advance.

And now I can see that the forum has truncated my (very long) message. Here's the most relevant part at the end:
| public void initializer();
| Code:
| Stack=1, Locals=1, Args_size=1
| 0: aload_0
| 1: pop
| 2: nop
| 3: nop
| 4: return
| LineNumberTable:
| line 23: 0
| LocalVariableTable:
| Start Length Slot Name Signature
| 0 5 0 this Lorg/apache/tapestry/corelib/components/Grid;
|
| public org.apache.tapestry.corelib.components.Grid(org.apache.tapestry.internal.InternalComponentResources, org.apache.tapestry.services.GridDataModelSource, org.apache.tapestry.services.BindingSource);
| Code:
| Stack=2, Locals=4, Args_size=4
| 0: aload_0
| 1: invokespecial #466; //Method java/lang/Object."<init>":()V
| 4: aload_0
| 5: aload_1
| 6: putfield #468; //Field org/apache/tapestry/corelib/components/Grid._$resources:Lorg/apache/tapestry/internal/InternalComponentResources;
| 9: aload_0
| 10: aload_2
| 11: putfield #470; //Field org/apache/tapestry/corelib/components/Grid._modelSource:Lorg/apache/tapestry/services/GridDataModelSource;
| 14: aload_0
| 15: aload_3
| 16: putfield #472; //Field org/apache/tapestry/corelib/components/Grid._$bindingSource:Lorg/apache/tapestry/services/BindingSource;
| 19: aload_0
| 20: invokevirtual #474; //Method org/apache/tapestry/corelib/components/Grid.initializer:()V
| 23: return
|
| }
|
and here's the synthetic accessor method:
| static org.apache.tapestry.grid.GridDataSource access$0(org.apache.tapestry.corelib.components.Grid);
| Code:
| Stack=1, Locals=3, Args_size=1
| 0: aload_0
| 1: astore_1
| 2: aconst_null
| 3: astore_2
| 4: invokespecial #80; //Method org/apache/tapestry/corelib/components/Grid._$read_parameter_source:()Lorg/apache/tapestry/grid/GridDataSource;
| 7: astore_2
| 8: aload_2
| 9: areturn
| LineNumberTable:
| line 26: 0
|
