Another issue that needs to be solved is association of a WAR deployment managed object to a tomcat Manager JMX entry. One possible way to correlate is to use the docBase property on the JSR-77 WebModule object.

Even better would be a way to set the context root on the ManagedDeployment of the WAR.

Is there an easy way for the AbstractWarDeployer to add a new ManagedProperty to the ManagedDeployment?

Where are you looking to use this?

For background, here is the mapping info I sent to the jopr team.

The component mappings are:

MBean, WebApplicationManager = Tomcat Session Manger
MBean, Servlet = Servlet metrics
MBean, WebApplication = Tomcat Deployment Info

The WebApplication and Servlet components are underneath a
ManagedDeployment with the name that is a combination of the host and
the context root.

The WebApplicationManager components are underneath a ManagedDeployment
with the same name as the context root.

To correlate these all together you should be able to strip the host
portion of the deployment name (so the first "//[^/]*/" portion, in this
case //localhost/)

To match to the deployment you should be able to match the docBase
property of the WebApplication component to the deployment name, by
stripping the URL protocol.

For example:

war deployment name =
vfsfile:/Users/jason/devel/jbossas/branches/Branch_5_x/build/output/jboss-5.1.0.GA/server/default/deploy/jmx-console.war/

WebApplication.docBase =
/Users/jason/devel/jbossas/branches/Branch_5_x/build/output/jboss-5.1.0.GA/server/default/deploy/jmx-console.war/

Here is what the tomcat MBean component tree looks like for jmx console:

ManagedDeployment: //localhost/jmx-console
ManagedComponent:
name=jboss.web:J2EEApplication=none,J2EEServer=none,
j2eeType=WebModule,name=//localhost/jmx-console
type=MBean, WebApplication
ManagedComponent
name=jboss.web:J2EEApplication=none,J2EEServer=none,
WebModule=//localhost/jmx-console,j2eeType=Servlet,
name=HtmlAdaptor
type=MBean, Servlet
...

ManagedDeployment: /jmx-console
ManagedComponent(
name=jboss.web:host=localhost,path=/jmx-console,type=Manager,
type=MBean, WebApplicationManager

I have expanded the ProxyManagedDeploymentFactory to support multiple mbeans under a single MBeanDeployment so that a single ManagedDeployment results. Now all three of the war related mbean types are found under a single ManagedDeployment, for example, the jmx-console has the following ProfileServiceDebugServlet view:

I have updated the WAR deployer to include a ContextMO object which contains the context-root of the deployment. This is can now be used as a more reliable way to map to these JMX mbeans:

ManagedDeployment: vfsfile:/devel/jbossas/branches/Branch_5_x/build/output/jboss-5.1.0.GA/server/default/deploy/jmx-console.war/
+++ ManagedComponent(name=ContextMO, type=(ComponentType{type=WAR, subtype=Context}), compName=null, attachment: org.jboss.web.deployers.AbstractWarDeployer$ContextMO
++++++ properties: [contextRoot = /jmx-console]

I don't think this is enough as a context root can live under different vhosts - and tomcat is emitting statistics for each vhost separately -- and users want this information.

Can you tell me how and when this ContextMO is added ? I tried in debug mode and it seems AbstractWarDeployer.build isn't called in my case on AS 5.1

ManagedObjects are only getting processed when the ManagementView is loaded. Which triggers MainDeployer.getManagedDeployment which builds all the managed objects.

OK thanks !
