I'm developing web application with OSGI. I have a maven configuration error which I cannot find. This is the complete source code: Download SH_27_test.zip for free on uploading.com

This is the POM file:

When I try to compile it with Netbeans I get this error: cd /home/rcbandit/Desktop/NetBeans/Prototype_3/SH_27; JAVA_HOME=/opt/jdk1.7.0_02 - Pastebin.com

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.
