Thanks. On the memory problem, it works "sometimes" when I put in adjusted memory settings. So I think the problem is related to launching a java app in the server, which is overloaded at this point. I still have more success when launching by hand. But I don't think it's a WO issue.
I don't think my Wonder install is that old. circa Jan. 31. I did some research, and saw others had the "not a subclass of WOComponent" issue before. (Your suggestion from then to log the name of the class showed it was org.apache.log4j.chainsaw.Main that was getting found.) The suggestion I followed that worked for me was to put the Main class in the same package as the Application class. Another suggestion was to rename the Main component to XYZMain (or whatever). Perhaps a fully qualified class name might work also (com.mypackage.components.Main). I also tried moving the ERJars jar down in the build order, but that caused an error (Your main bundle is JavaFoundation...)
