hi, I started using the orion feature, that you can declare a child application of another one. at first it worked fine but I'm beginning to get more and more weird errors, e.g. say I have three applications named parent, child1 and child2. in addition to that I have used the global-application to import some common utility classes used by all applications. when I start orion I get an error message saying that one of the utility classes (in the library path of the global application) cannot be found when deploying child1 and child2: Error loading package at file:/home/krueger/devel/projekte/s7procurement-deployment/devel/ejb/, Error loading class 'com.signal7.procurement.ejb.administration.CompanyBean': java.lang.NoClassDefFoundError: com/signal7/ejb/EntityAdapter when i remove child1, child2 from server.xml store, put them back in, they deploy normally and work. on another orion installation I have the effect that the narrow operation on a looked up home interface leeds to a class cast exception because there is an object of some internal com.evermind.server... class instead of my home interface wrapper. the identical deployment settings, freshly checked out from cvs work well on the same version of orion on the development machine. suddenly after a few requests on the servlet it works. before I incest more effort trying to find a pattern in this weird behaviour I would like to hear from others who have used this stuff if they think it works. if I'm the first to use it extensively I don't know if I have the nerve to go on and would consider solving my problem some other way. any input appreciated, maybe magnus or karl could share some internals on how this parent/child/global application stuff works internally (classloader hierachy, jndi tree, implications) so I can bo better than with just brainless trial and error. robert (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de
