my OpenEJB block uses a similar hirarchical classloader system. because i did the classloader by myself as a part of my iChilli app server i am configuring the classloaders within the block's config.xml file.
additionally the iChilli app server that i am currently developing starts several servers (a web container, an ejb container, a jms server etc.) because a ejb container needs to now when a content of a specific directory will change it is possible to add a <monitored>true</monitored> flag to a specific classloader. that enables a server (ex.: openejb) to register itself as a ClassLoaderListener. that way a ClassLoader will deliver added/deleted/changed events to the appropriate server. allthough as i said i created this classloader systems a couple of weeks ago and i did it within three days, so i didn't test every possible scenario that could occure while using the classloaders. if you want i can send u my configuration files and some UML digrams that illustrate what i have described above. regards daniel s. haischt -- > -----Ursprungliche Nachricht----- > Von: Peter Donald [mailto:peter@;apache.org] > Gesendet: Samstag, 2.
