Thanks.  I just need the servlet to read a flag that I put into the 
owner attribute of the deployment.  So I should be OK.

Incidentally, I find that this is something I run into once in awhile.  
I need a subsystem to communicate with a deployment's application code.  
The other way I've done this is to stuff things into the ServletContext 
using a DeploymentUnitProcessor and the JBossWebMetaData.

If anyone knows a third option I'd love to hear it.
