In the current .pom you are building an ear and you are giving the same ear as a warModule.
You should give a .war artefact for webmodule in the ear-plugin

When I try to compile it with Netbeans I get this error:
http://pastebin.com/whxuSb7V
The problem occurs when I add #Datasource. It seems that I'm missing something in the POM file but I don't have idea what it is?
Any help will be highly appreciated.
Best Wishes

Check out Maven: Unresolved references to [org.osgi.service.http]. I think he had the same problem that he managed to resolve by including specific packages that need to be imported.

This is the solution:
<Import-Package>${pom.groupId}.api, org.osgi.framework</Import-Package>
Should be:
<Import-Package>*</Import-Package>
I hope that this will be helpful for someone.
