Hi, Krzysztof,
Greatly appreciate your effort and your help. I also found couple of solutions from other website's posts. One of them is your first solution and another is to use newInstance(package.ObjectFactory.class), which would not apply to my simple example since it's non-schema-derived, but did work for my original legacy code, which is schema-derived. Looking over your solutions, both are classloader-based. I was a little uncomfortable playing with classloader at application layer. Shouldn't the framework have taken care of it? How does an application developer know what classloader to use in general? Interested in hearing your opinion on this. Thanks again.

I had to create a small project. One solution which worked for me was following line jaxbContext = JAXBContext.newInstance("mil.army.security.ts3.jaxb.personnel", this.getClass().getClassLoader()); Another one which worked for me was setting if the context class loader try { Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader()); jaxbContext = JAXBContext.newInstance("mil.army.security.ts3.jaxb.personnel"); } finally { Thread.currentThread().setContextClassLoader(cl); } This ensures the JAXBContext uses the class loader of your bundle to instantiate the JAXB Context. In this way your classes are visible for the JAXBContext. Please try these solutions. I have attached my sample project. I have made them from one of the cxf samples and it con have too many unnecessary dependencies. Feel free to play with this.
