Your one should have application precedence (the default), the core one has the lower built in precedence. | @Name("org.jboss.seam.security.identity") | @Scope(SESSION) | @Install(precedence = BUILT_IN, classDependencies="org.drools.WorkingMemory") | So if you define a component with the same name and leave the precedence as default it should prefer your component over the default one. If you're getting a clash like that you are probably either specifying @Install( BUILT_IN ) by accident or have the component duplicated somewhere. Cheers. Mike.
