Subject Re: MBeans?
Date Tue, 01 Oct 2002 15:05:19 GMT
I am building a custom user system which extends that which tomcat 4.1.12
did - basically an extended version of the UserDatabaseRealm and
UserDatabase - to meet a companies specific security needs.  As such, any
classes I write for this go into the server/lib directory.  I noticed I
could disable JMX support and everything worked fine... - but since this is
the first I have heard about JMX, I would like to know more about what JMX's
role is in J2EE systems.  Funny how new features in Tomcat somehow get me
introduced to new java libraries I never knew about...

I made the decision to do this for many reasons - but primarily because I
like the new administration features of 4.1.12, and (except for encoding
issues in realms), I like the catalina interface.

I have heard a lot of good things about JBoss - mostly integrating various
J2EE components - however I am not yet familiar enough with ejb's, and jms
to use them in a production environment.  Eventually, when I get out of
school, I will probably delve into it full time - but until then I need to
just figure out how to best provide good service to the companies that
supply my fledling family their bread and butter.  :)

What kind of bean what you like to add so that tomcat knows about it?

In the (current) tomcat world, there are two kind of MBeans: its own and
yours.  Yours are under your webapp, visible only to you, and tomcat
doesn't want to have anything to do with them.  Its own MBeans are
visible only to it, and you shouldn't have anything to do with them.
This might change in the future.

JBoss supports a nice dynamic MBean model.  It may be more suitable for
your task.  Which goes back to the original question, what exactly are
you trying to do?
