Hi John,
I managed to fix this. getAvailability() was looking for an attribute that
didn't exist (different Tomcat versions I guess?).
Would this be the correct forum to ask (in the near future) about how to
maybe add an auto-discovery post-processing step to extract dependencies and
the like?
Thanks,

This question is probably best to post on the user forums - get it out
there to the user community.
This problem does sounds familiar. I think I recall at least one other
person saying that they see this too.
Post a thread on the Jopr user forum at
http://www.jboss.org/index.html?module=bb&op=viewforum&f=292 and provide
information like:
1) Which version of the core RHQ engine are you using? Which version of
the Tomcat plugin? Released versions or builds from trunk?
2) Post the relevent agent log messages here.
Thanks,
John Mazz

Subject: [jopr-dev] Introduction and first question
Hi,
I am interested in some slight modifications to Jopr and RHQ that I am
going to try my luck with over the next couple of weeks. In particular, I
want to introduce dependencies between components (on a single host, between
components on differents in the same domain and inter-domain) that can be
displayed to users. I am also interested in plugins for SOAP runtimes, such
as Axis, the ActiveBPEL engine and some Grid middleware, all of which I will
hopefully be able to contribute.
My first question is to do with the new Tomcat plugin. Discovery of Tomcat
works, but the plugin mistakenly insists that the Tomcat instance is not
available. I found that its EMSConnection is not servicing any requests,
which results in a corresponding exception and the connection to be closed.
Hence, the plugin does not successfully collect any metrics I would like it
to.
JConsole on the same host works fine and allows me to inspect all the
MBeans.
Does anyone have any ideas why the the Tomcat plugin's connection is not
responsive (using the same URL as for JConsole)?
Thanks,
-- Bruno
