Unfortunately I couldn't get it to work. I'm really new to gbeans, though... 
Maybe someone here (developer?) knows how this is supposed to be done?
First I tried putting it inside the <application> root tag and it gave me:
org.apache.xmlbeans.XmlException: Invalid deployment descriptor: errors:

Should work if its the last element... although I'd expect you'd get the same exception as in the openejb-jar.xml. 





Same happened when I tried putting it inside <module>.


that won't work


Then I tried putting
it inside <openejb-jar> and it gave me:
Unable to set attribute abstractNameQuery to ?name= DefaultWorkManager# org.apache.geronimo.common.DeploymentException: Unable to set attribute 
abstractNameQuery to ?name= DefaultWorkManager#
        at
org .apache .geronimo .deployment .service.SingleGBeanBuilder.setAttribute(SingleGBeanBuilder.java:90)
Is there another exception, the cause, in the stack trace? If so, if you show the complete stack trace we might be able to diagnose the problem.

I tried putting the gbean-definition in config.xml, inside the module:

   <module name="************/car">
       <gbean name="WorkManagerBinding">
           <attribute name="name">DefaultWorkManager</attribute>
           <attribute name="abstractNameQuery">?name=
DefaultWorkManager#</attribute>
           <reference name="Context"/>
       </gbean>
   </module>

and I got:
org.apache.geronimo.kernel.config.InvalidConfigException: New GBeans must be specified with a GBeanInfo and a full AbstractName configuration=designfa 
ctory/lobby/0.2.0/car gbeanName=WorkManagerBinding

Any help?

I assume you are talking about the j2ca work manager we've had for a
long time rather than a newer choice -- I think the ee concurrent spec 
may also have a work manager and I don't know about ejb 3.1.

The default work manager isn't bound in jndi right now.  To bind it
you can include a binding gbean like we use for the transaction
manager -- see the plan at plugins/connector/transaction/src/main/ plan/ 
plan.xml or inside the transaction car.  I think yours will look like
this:

    <gbean name="WorkManagerBinding"
class="org.apache.geronimo.gjndi.binding.GBeanBinding">
        <attribute name="name">DefaultWorkManager</attribute>
        <attribute name="abstractNameQuery">?name=
DefaultWorkManager#</attribute>
        <reference name="Context">
            <name>JavaContext</name>
        </reference>
    </gbean>

I think the work manager will then be at java:DefaultWorkManager

I think you can put this gbean in your geronimo plan for your web app
although there might be ordering issues if you try to look it up
during servlet initialization... you could experiment.

I've tried searching for this a lot, but I haven't found any
documentation
yet of any JNDI name for DefaultWorkManager or anything similar.

Any advice? The WorkManager is to be used by a session bean.
