Can you try adding to the pom.xml file under dependencies
<dependency> <groupId>org.apache.xbean</groupId> <artifactId>xbean-spring</artifactId> <version>3.5</version> </dependency>
thanks for your help - found the mistake meanwhile.
I forgot to replace "pom" with "bundle" in the pom.xml - very silly mistake, but after hours of searching I simply couldn't detect the error at first.
Again thanks for your help.
