I am using Fuse Fabric 6.1.0-redhat-379. We migrating spring based application to blueprint osgi application. Previously we are using spring orm with hibernate for accessing db. I tried to port the spring orm (service mix bundles) to blueprint container. Now I am facing error where entity object present inside mapping resource file is not found in hibernate-core bundle. But same is present in my application bundle.
