Setting up a CommonJ Timer Manager in Websphere

Question

In the Web.xml I have:

<resource-ref>
    <res-ref-name>java:/comp/env/tm/TimerManager</res-ref-name>
    <res-type>commonj.timers.TimerManager</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Unshareable</res-sharing-scope>
</resource-ref>

In the java code I have:

    TimerManager tm = (TimerManager) ic.lookup("tm/TimerManager");
tm.schedule(new CleanupListener(), 0, 10*1000); // CleanupListener class is my TimerListener

So when I run the code, the Timer kick in successfully but right after the code crash with the following exception:

javax.naming.ConfigurationException: NamingManager.getURLContext cannot find the factory for this scheme: java

I have no idea why. when I change the lookup with this: TimerManager tm = (TimerManager) ic.lookup("java:/comp/env/tm/TimerManager"); This is even worst, the Timer never kick in and I do have this following exception: db.common.util.ServiceLocatorException: javax.naming.ConfigurationException: NamingManager.getURLContext cannot find the factory for this scheme: java

Please help, very important. Thanks

Answer 1

Try using

java:comp/env/tm/TimerManager

in place of

java:/comp/env/tm/TimerManager

If that doesn't help. please post your full deployment descriptor and bindings file (web.xml and either ibm-web-bnd.xml or ibm-web-bnd.xmi) to ensure that the configuration within this files is correct.

Thanks for posting the files. I think the problem is that web.xml version 3.0 is not compatible with ibm-web-bnd.xmi. Try either using web.xml version 3.0 with ibm-web-bnd.xml, or otherwise use an earlier version web.xml with ibm-web-bnd.xmi.

Answer 3

You reverted valid syntax.

Within web.xml:

<res-ref-name>tm/TimerManager</res-ref-name>

Within source code:

ic.lookup("java:comp/env/tm/TimerManager")
