Ok, I think I have the picture.
What you are asking for is not directly possible.
IMHO, I think you should either get the MBeanServer to depend on the SNMP guy.
If that is not possible, then make the SNMP guy into a facility (which may be
interesting anyway), by declaring that it needs the root containment model in
its context.
That is done by;
/**
* @avalon.entry key="urn:composition:containment.model"
*
type="org.apache.avalon.composition.model.ContainmentModel"
*
*/
public void contextualize( Context ctx )
throws ContextException
{
m_Model = (ContainmentModel) ctx.get(
"urn:composition:containment.model" );
}
That will guarantee the SNMP guy to be running before anything else.
Btw, any contribution in the SNMP area is of highest interest, even if it is
not complete or generic. (Stayed tune for further info of how to get your
hands dirty quickly with Merlin/Metro.)
