Re: Configure datasource to work with JBoss style lookups?

[Mangan <ma...@aptrut.com>]

Well, you are right about the classpath error. I've fixed that now. 

The solution you propose is more or less impossible for me to implement
because the datasource lookup I described earlier is found in a layer
underneath the class I'm running my unit tests on. I don't have the
possibility to change the lookup. So is it possible to do the same thing
directly in the openejb.xml or by passing parameters to the JVM directly?

Thanks!
