Thomas. -------- Original-Nachricht --------
Hi, I tried it with right click and combined with the properties solution from Stephen both doesn't work. I've put my Definitions module and put the classes into the Business.Implementations module where the persistence unit is defined nothing worked. Now I will try to do the tutorial, maybe I then get a hint what went wrong. By the way does someone know this: "Warning - could not install some modules: Business.Implementations NetBeans Module - The module derby was requested in version >= 10.4.2000000.689064 but only 10.4.2000000 was found. Another module could not be installed due to the above problems. " This is the error message when I try it with derby(not embedded). I just insert a dependency <dependency> <groupId>org.apache.derby</groupId> <artifactId>derby</artifactId> <version>10.4.2.0</version> </dependency> into the pom.xml. The first version number is the version in the Manifest file of derby but it's the osgi version why does netbeans bother? Is there a workaround or need I a derby version without the osgi definitions?

Ditto for what does this have to do with anything. Please stop cross-posting from the NetBeans list. Anyone interested in NetBeans should already be subscribed; those who aren't don't want to see this...
