[jopr-dev] more on plugins/classloaders

Tell me where I am wrong. Suppose I am writing plugin "Z" - there are plugins A, B, C and D that may or may not be deployed. Here's Z's descriptor: <plugin name="Z"> <depends plugin="A" /> <server name="Z1.server"> <runs-inside> <parent-resource-type name="B1.server" plugin="B"/> <parent-resource-type name="C1.server" plugin="C"/> <runs-inside> </server> <server name="Z2.server"> sourcePlugin="D" sourceType="D1" > </server> </plugin> This means that if I deploy Z, then: 1) plugin 'A' MUST be deployed as well (i.e. if A does not exist, Z will not deploy). 2) plugin D may or may not exist, if it doesn't exist, then.... what is Z2.server? Do we ignore that? Since D1 type definition doesn't exist, then Z2.server can't possibly exist. I think we ignore Z2.server as if it was never there 3) plugin B and plugin C may or may not exist. If they don't exist, then Z1.server is meaningless. I think we ignore Z1.server if B and C are missing 4) When Z1.server is detected, the component's classloader includes what? Its parent classloader is A classloader plus B classloader? Or C? 5) what if there are TWO or more <depends> tags - say <depends plugin="E"> in addition to above. Does Z plugin classloader include the A and E classes? I think so (not sure how I'm gonna implement that) 6) where does this "child first" or "hidden" configuration go? What is its semantics? Is there anything else i'm missing that I need to consider? anything I need to make sure I impement?
