Hello, Looking at the JBoss MC source code I can see that a "describe" deployer can add capabilities information before the classloader gets created("ClassLoaderMetaData.setCapabilities()"), thus allowing dependency resolution for a unit being deployed. Now, I wonder about the deployer themselves: How could a deployer (that is being deployed) inform MC of its own capabilities? Is there a mechanism to do that? The only option I can see, so far, is to create another deployer (in a different deployment unit) that would declare the capabilities my deployer. But I can't shake the feeling that I am probably trying to kill a fly with a hammer... ;-) Thanks for your help. Gilles.
