Hi, Next time, it should be helpful if you can show us some of your code. I'll try to answer you and I hope I well understood your problem.
If you use JAXB in servicemix (or in an OSGi environment), please pay attention : In servicemix, every bundle has its own Class loader. So when you want to use the JAXB functions (Unmarshall/Marshall) in your bundle B with your JAXB classes that are deployed in a bundle A, you have to specified which ClassLoader JAXB must use. Actually, by default, it uses the ClassLoader of the current thread. So if you are in the bundle B, it use the Class loader of the bundle B. If you want to use the ClassLoader of the bundle A (that's what you should do in this case), you can do like : //specify which class loader JAXB should use JAXBContext jc = JAXBContext.newInstance(ObjectFactory.class.getPackage().getName(), ObjectFactory.class.getClassLoader()); And then you can use the Marshaller/Unmarshaller by calling jc.createMarshaller()/jc.createUnmarshaller() I hope it can help you.

Please make sure that you are specifying the proper ClassLoader. ] I see here that, even though servicemix is having its own JAXB implementation , it is still accessing the JDK's JAXB api. I am using JDK 6 update 21 and servicemix version is 4.4.2. Could anyone please suggest me what can be done here to resolve this exception ? I am in urgent need and already spent 2 days in googling this stuff. Quick response will be appreaciated .
