Then we need an in memory vfs uri handler that can load the generated classes from a uri like vfsmemory:/aop-domain/classes. I thought Bill had done some work along the lines of an in memory vfs handler, but I don't see a url handler for it. There are org.jboss.virtual.plugins.context.vfs.AssembledDirectory/AssembledFile that allow for virtual aggregating directories/files on top of other vfs urls, but not an in memory type. Its easy enough to add such a handler. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4095296#...
