Subject Newbie Question about Plugins
Date Wed, 06 Oct 2010 23:04:33 GMT

Hi everyone,
I want to develop a simple plugin for ActiveMQ, but following the examples
on
http://activemq.apache.org/developing-plugins.html
doesn't get me anywhere.
My Plugin doesn't do anything it's just a MyPlugin.class implementing
BrokerPlugin and a MyBroker.class extending BrokerFilter with a call to
super(broker). So the following Questions are more about getting ActiveMQ to
include MyPlugin rather than anything complicated.
So my first Question is where do I have to put the classes so that activemq
finds them on startup?

My Second Question is where can I add the beans pointing to my Plugin?

I tried adding plugins="#MyPlugin" in the broker tab but I get following
error

So plugins is not an allowed atrribute despite what's written on the link
posted above?!
I also tried adding my plugin with plugins tag and I got this Error
Invalid content was found starting with element 'plugin'. One of
'{WC[##other:"http://activemq.apache.org/schema/core"]}' is expected.

These Error are not that the class files can't be found but syntax errors
right?
So are the examples of the Website wrong?
