what does modeler do?
the thing i like about the modeler package (http://jakarta.apache.org/commons/modeler/docs/api/index.html) is it to define the model bean metadata info in an xml file, and then the mbeans will be created accordingly. i think tomcat uses the modeler package to build its model beans for management.
i looked at a few mbeans in jboss. they all seem to be standard mbeans. do you use model bean/dynamic bean often inside jboss?
have a look at the xmbean.dtd
