This Bundles uses JAXB . This bundle alos exposes JAXRS services using CXF DOSGI. So I have also deployed CXF DOSGI bundle . My problem is when my bundle try to initialize the JAXB context , it throws a class cast exception . Further debugging revealed that JAXBConext is using BundleClassLoader to load the Context factory . com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to javax.xml.bind.JAXBContext To avoid this conflict , I am trying to get  my bundle to load JAXB either from Jboss AS7 or from the JDK 1.6 . I read some article that I can use bootdelegation and specify some packages ao that All these packages will be loaded by parent class loader . I tried setting bootdelegation for javax.xml.bind.context and for com.sun.* but there is no change in behavior . I am setting  using  -Dorg.osgi.framework.bootdelegation=sun.*,com.sun.*,javax.* I have also tried setting *org.osgi.framework.system.packages.extra in server configuration , but that doesn't help either. * Has anyone used this before ? Can someone share thoughts if I am on right track ? Is there any other way to resolve this issue ? Appreciate any insights.
