I am working with Seam, but I think this is an EJB3 problem, hence posting in this thread. I have a working test environment set up for my Seam application that performs nicely when I put all my configuration files in the same location as the classes. That is, it looks something like this: classes/ | net.my.packages | seam.properties | myDatasource-ds.xml | META-INF/ | usual stuff | WEB-INF/ | usual stuff However, I like to be very strict about keeping clean separation between different types of resources. It would be ideal to keep all the configuration files in a location like resources/ without copying them into classes/, then add both to my classpath at test runtime. Section 9.2 of the Seam reference says that any location containing a seam.properties file will be scanned for components. This works, sort of, but I get ugly errors which I do not understand. I have stack traces on my wiki here: http://sidragon.net/wiki/JBoss_Seam_test_environment#Symptoms Any suggestions? Is it possible to keep this divide?
