[jboss-dev-forums] [JBoss Microcontainer Development POJO Server] - Adding a ClassLoader import exclusion filter

[jason.greene@jboss.com]

We seem to have some cases where we need an isolated deployment to ignore specific packages from a parent. A common example would be a WAR shipping it's own implementation of JSF. 

Anther similar case is a deployment wanting to exclude particular resources. As an example a child deployment of an isolated ear may call getResources("META-INF/common-name.xml") and end up pulling in stuff from the server that it does not actually want (in particular non isolated deployments). 

To solve the former, I was thinking about adding an enhancement to classloading that would allow a policy which excluded a package list from all parent and/or module imports. 

Does this sound reasonable? Or am I missing something?
