Hello,
I'm trying to launch asynchronicity and I've faced with a number of problems.
What I've done:
| @Stateless
| @Name("prevedMedved")
| public class PrevedBean implements IPreved {
|
| @Logger
| private Log log;
|
| @In(create = true)
| TaskHandler taskHandler;
|
| @Observer("org.jboss.seam.postInitialization")
| public void sayPreved() {
| log.info("PREVEEED MEDVEEEEEED!!!!! ##################");
| log.info("IBVOKING TASKING4 after 1 minute");
| Calendar cal = Calendar.getInstance();
| cal.setTime(new Date());
| cal.add(Calendar.MINUTE, 1);
| taskHandler.sayGreeting("PREVED, KROSAV4EGI", cal.getTime(),
1000L);
| }
| }
| @Local
| public interface TaskHandler {
| @Asynchronous
| void sayGreeting(String greeting, @Expiration Date date,
@IntervalDuration Long interval);
| }
|
| @AutoCreate
| @Name("taskHandler")
| public class TaskHandlerBean implements TaskHandler {
|
| @Logger
| Log log;
|
| @Override
| public void sayGreeting(String greeting, Date date, Long interval) {
| log.info("greeting: #0 at #1", greeting, new Date());
| }
|
| }
I just tried to make tasking by example given in documentation.
When the method sayPreved is being invoked after deployment the method
sayGreeting is invoked immediatly - not after 1 minute as I expected. In
addition I don't see any recurrent invocation. What am I doing wrong?
Another issue. I tried to add <async:timer-service-dispatcher/> to the
components.xml as it is written in documentation to use EJB3 Timer. In
application deployment I got initilization exception:
.....
Caused by: org.dom4j.DocumentException: Error on line 44 of document : The
prefix "async" for element "async:timer-service-dispatcher" is not bound.
Nested exception: The prefix "async" for element
"async:timer-service-dispatcher" is not bound.

at org.jboss.seam.util.XML.getRootElement(XML.java:16)
at
org.jboss.seam.init.Initialization.initComponentsFromXmlDocument(Initialization.java:130)
As I understand, the schema location for async is not specified. Is it bug?
Thanks
