hi all,
i'm new to JBX so apologies if this question sounds niave.
I've an application which has a number of stateless session beans running the business
logic. I'd like to expose some of the methods on these beans to JMX so that i can
manage the beans when they are deployed.
However, i can' t seem to deploy the mbeans ;-( I've the session beans and mbean
interfaces packages into a jar file and this jar file along with the corresponding
jboss-service.xml file are packaged into a .sar. When i deploy the .sar i get the
following error :
2004-04-22 15:19:32,639 ERROR [org.jboss.deployment.MainDeployer] could not create

if i convert the session bean into a plain java file it seems to work fine but this
is not ideal as i need the other features of session beans.
so my question is, is what i'm attempting possible/a good idea or are SSLB's just not
mbeanable??
thanks in advance,
colum.
