Weblogic 12c cluster and EJB 3.1 timers

Question

Hello!
I'm using Weblogic 12c (12.1.1.0) Cluster.
I configured the cluster to use database for EJB timers (ACTIVE and WEBLOGIC_TIMERS tables). I created a persistence store with logical name 'timerst'.
The timer bean:
@Stateless
public class TimerTestBean {
     private Logger logger = Logger.getLogger(TimerTestBean.class);
     @Resource
     TimerService timerService;
     public void settimer() {
          logger.info("settimer");
          timerService.createTimer(30000, "New timer");
     @Timeout
     public void zszszszs(Timer arg0) {
          logger.info("Tick");
          settimer();
weblogic-ejb-jar.xml:
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-ejb-jar xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-ejb-jar" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd http://xmlns.oracle.com/weblogic/weblogic-ejb-jar http://xmlns.oracle.com/weblogic/weblogic-ejb-jar/1.3/weblogic-ejb-jar.xsd">
<!--weblogic-version:12.1.1-->
<wls:weblogic-enterprise-bean>
<wls:ejb-name>TimerTestBean</wls:ejb-name>
<wls:stateless-session-descriptor>
<wls:timer-descriptor>
<wls:persistent-store-logical-name>timerst</wls:persistent-store-logical-name>
</wls:timer-descriptor>
</wls:stateless-session-descriptor>
</wls:weblogic-enterprise-bean>
<wls:timer-implementation>Clustered</wls:timer-implementation>
</wls:weblogic-ejb-jar>
It seems the timer starts normally.
When there timer fires, I've got the following error message:
java.lang.ClassCastException: timertest.TimerTestBean_9kqf6o_Impl cannot be cast to javax.ejb.TimedObject
What is wrong?
Thanks

Answer 1

Issues have been found with @Schedule and @Timeout annotations in WLS clustered timer implementation.
The problem is fixed with 12.1.2 WLS version. Patch exists for 12.1.1.0 version.
Please download and apply Patch 13417115 from Oracle Support Portal.
