XMBean and SubscriptionList

[alfred.rsa]

Hi

I have changed my mbeans to xmbeans by having the class extend xmbean. But now my in my *-service.xml the SubscriptionList attribute fails with the following: DeploymentException: No Attribute found with name: SubscriptionList

this is my xml


<subscription-list>

</subscription-list>


Is this even the right way to add subscriptions for XMBeans? I would actually like the XMBean to subscribe to "global" jmx events and filter them rather than subscribing to specific MBeans

Regards
Alfred

Your xmbean descriptor should describe all operations/attribute that appear on your mbean interface, including:

<attribute access="read-write" getMethod="getSubscriptionList" setMethod="setSubscriptionList">
 <description>The subscription list configuration/description>
 <name>SubscriptionList</name>
 <type>org.w3c.dom.Element</type>
</attribute>

Sorry, this is my xml

<subscription-list>

</subscription-list>

Last try...

<attribute name="SubscriptionList">
 <subscription-list>
 <mbean name="FNB.Commercial.BFLo:service=FileEventListenerService"/>
 </subscription-list>
 </attribute>

This is the -service.xml descriptor you are showing, not the xmbean one. Better read the xmbean section in the FAQ:

http://wiki.jboss.org/wiki/Wiki.jsp?page=FAQJBossJMX

Or the section on how to write listener mbeans.

Why you are using xmbeans?

Hi Dimitris

Here is the rest of my config - I only showed the notifications.
I am using XMBeans because it seemed to be the most convenient way of adding method/parameter names and descriptions in the JMX console. I tried normal MBeans, dynamic and model mbeans as well. I like XMBeans the best. Should I not use them?

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE server PUBLIC "-//JBoss//DTD MBean Service 4.2//EN" "http://www.jboss.org/j2ee/dtd/jboss-service_4_2.dtd">

<server>
 <mbean code="za.co.fnb.bflo.eventlistener.FileEventListenerService" name="FNB.Commercial.BFLo:service=FileEventListenerService" xmbean-dd="META-INF/FileEventListenerService.xml">

 <attribute name="ConfigurationFilename">FileEventListenerService.xml</attribute>
 </mbean>
 <mbean code="za.co.fnb.bflo.dispatcher.JMSEventDispatcherService" name="FNB.Commercial.BFLo:service=JMSEventDispatcherService" xmbean-dd="META-INF/JMSEventDispatcherService.xml">

 <attribute name="SubscriptionList">
 <subscription-list>
 <mbean name="FNB.Commercial.BFLo:service=FileEventListenerService"/>
 </subscription-list>
 </attribute>
 </mbean>
</server>

and

XMBeans are fine. You just need to add the SubscriptionList attribute definition in the xmbean descriptor.

Thanks - I did try that but I couldn't find an example of it, this is what I tried and it didn't work

<attribute access='read-write' getMethod='getSubscriptionList' setMethod='setSubscriptionList'>
 <description>MBean Attribute.</description>
 <name>SubscriptionList</name>
 <type>java.util.List</type>
 </attribute>

I found my mistake, thanks for your patience.

The code should be

<attribute access='read-write' getMethod='getSubscriptionList' setMethod='setSubscriptionList'>
 <description>MBean Attribute.</description>
 <name>SubscriptionList</name>
 <type>org.w3c.dom.Element</type>
 </attribute>
