MBean Dependency not working as expected .

vickyk Aug 6, 2008 7:39 AM

I have the following contents in the MBean deployment descriptor

<?xml version="1.0" encoding="UTF-8"?>
<server>
 <mbean code="org.jboss.test.jca.mbean.RaDependsOnMe"
 name="jboss.test:test=RaDependsOnMeMBean">
<depends>jboss.test:name=test</depends>
 </mbean>
</server>

The jboss.test:name=test is not present so I would expect that the RaDependsOnMe not to get registered/available for usage

But to my surprise I see the MBean jboss.test:test=RaDependsOnMeMBean available from the jmx-console and I am able to call the sayHello() operation from the jmx-console .

I tried this on Jboss5 , Jboss4.2 and Jboss4.0.5 .

This looks to me as the bug .

No. Depends is a contract on the create/start lifecycle not registration in the
MBeanServer. To get what you want in JMX, you'd have to introduce
something like the MC demand into the jmx xml.
<mbean code="org.jboss.test.jca.mbean.RaDependsOnMe" name="jboss.test:test=RaDependsOnMeMBean"> <demand whenRequired="Instantiated">jboss.test:name=test</demand> </mbean>

Which doesn't currently exist within the -service.xml

Do you know how annoying it is when somebody claims "bug"
without even referring to the documentation/specification of the feature used? :-)

I was guessing the same behavior but wanted to clarify it without digging into code ;)

And that's exactly why it is a BAD POST.

Somebody who has done no research whatsover is claiming they have a bug
to get attention.

Complete waste of people's time. :-(
