--------------------------------------------------------------
I'm trying to use an EJB 3.1 Timer to schedule a recurring task every 5 minutes.
I'm using JBOSS 6.0.0.Final.
This is the simple code I have deployed:
import javax.ejb.Schedule;
import javax.ejb.Stateless;
import javax.ejb.Timeout;
/**
* Session Bean implementation class AlerMonitorBean
*/
@Stateless
public class AlerMonitorBean {
/**
* Default constructor.
*/
public AlerMonitorBean() {
// TODO Auto-generated constructor stub
}
@Schedule(minute="0/5")
public void GestisciAlert() {
System.out.println("Gestisti Alert - Tick"+System.currentTimeMillis());
}
@Timeout
public void GestisciTimeout(){
System.out.println("Timeout");
}
}
import javax.ejb.Schedule;
import javax.ejb.Stateless;
import javax.ejb.Timeout;
/**
* Session Bean implementation class AlerMonitorBean
*/
@Stateless
public class AlerMonitorBean {
/**
* Default constructor.
*/
public AlerMonitorBean() {
// TODO Auto-generated constructor stub
}
@Schedule(minute="*/5")
public void GestisciAlert() {
System.out.println("Gestisti Alert - Tick -> "+System.currentTimeMillis());
//TODO: insert code
}
}
I notice the following in Jboss Console:
15:40:00,006 INFO [STDOUT] Gestisti Alert - Tick -> 1294238400006

I expected that method "GestisciAlert" was called once every 5 minutes.....
Every 5 minutes Timer starts and activates target method several times (about once per second) for a minute....
Then it stops and starts again after 4 minutes.
Hope someone can help me.

[jBPM] - can not end subprocess in concurrent execution (jBPM4.4)

Hi!
I have a problem with jBPM 4.4 when I try to end a subprocess instance in a concurrent execution.
This image show an example process:
http://community.jboss.org/servlet/JiveServlet/showImage/2-561928-7482/su... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-561928-748...
The process should execute a subprocess and wait of a signal in the concurrent execution. When a signal arrive, an external activity behavior (end subprocess) should call that will end the subprocess and both executions will join.
I can run this process correct with jBPM 4.3 but when i try to run with jBPM 4.4 the follow JbpmExecution throw:

I tried to end the subprocess instance like this:
executionService.endProcessInstance(processInstanceId, "remove");
(processInstanceId is the id of the execution in activity 'subprocess')
I also tried to send a signal to this execution but it throw the same exception.
It seems that I have to end the subprocess instance first, so I tried something like that but it doesn't work and throw the exception.
public void endProcessInstanceByIdCascade(final String processInstanceId) {
Command<Object> command = new Command<Object>() {
public Object execute(Environment environment) throws Exception {
ProcessInstance processInstance = executionService.findProcessInstanceById(processInstanceId);
Execution subProcessInstance = processInstance.getSubProcessInstance();
if (subProcessInstance != null) endProcessInstanceByIdCascade(subProcessInstance.getId());
executionService.endProcessInstance(processInstanceId, "remove");
return null;
}
};
processEngine.execute(command);
}
Did I make something wrong or is this a bug in jBPM 4.4?
Thank you for help!
Phil

[JBoss Web Services] - How to define context-root or URL for web service?

Hi,
I would like to define the URL under which a web service is reachable. My web service is based on a stateless session bean. I know, that there is the @WebContext annotation, but I would like to keep my code free from any JBoss specific things.
The session bean/web service is implementen in a JAR file, which then is included in an EAR file. In fact, I have several JAR files, some of them implementing their own web services. All of them are included in the EAR file. This EAR file is project specific, and I would like to define the URL (or at least the context root) in that file, leaving the JAR file untouched.
Is such a solution possible? If yes, how can I achieve that?
Thanks and best regards,
Heiner

[JBoss Web Services] - Web Service deployment failed after JSF update

"Web Service deployment failed after JSF update"
To view the discussion, visit: http://community.jboss.org/message/581583#581583

Hi,
I have a problem with deployment of EJB3 web service after upgrading JSF. IMHO, these two things should not be linked to each other, but reality has a different opinion :0 .
I'm running JBoss AS 5.1.0 GA and updated JSF to 2.0 (Mojarra 2.0.3). Deploying any WAR works perfect, but when I deploy a JAR package containing a web sevice, I get the following error:
> Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener
> com.sun.faces.config.ConfigurationException: no web.xml present
Well, thats right. There is no web.xml, as there must not be a web.xml in a JAR file. Unfortunately, it prevents my complete EJB-package from beeing deployed and started. I tried to add an empty web.xml file. As a result, I didn't get any error message, but the application is still not started, web service not initialized, ...
Is there any workaround possible?
Best regards,
Heiner
