I am using OpenJPA as JPA provider. I have created the small OSGI bundle project with the JPA2.0 support. This bundle provides the persistnce functionality to its clients.

I created another client bundle to consume the above persistence service. When I start the client bundle service using Felix framework I am getting bellow error,

java.lang.NoClassDefFoundError: javax/naming/NamingException

Complete stacktrace

I am very new to OSGI bundle development. Please help me to resolve this issue.

Your client bundle need to import package javax.naming. Add this to the list of imported packages indicated by Import-Package.

By the way you might have additional dependencies that will be found to be missing after you resolve the problem with javax.naming. You really shouldn't write your MANIFEST.MF by hand because it is error-prone and contains duplicate information. You should use a tool like bnd or Bndtools.

Update: In fact, OpenJPA itself fails to import the package javax.naming, as shown by the following part of the stack trace: "javax.naming.NamingException not found by org.apache.openjpa [109]".

Therefore, OpenJPA is broken.
