Assuming you already have the POJOs that you are mapping with hibernate, then you can already use them with JAXB. JAXB is configuration by exception which means you only need to add annotations where you want the mapping behaviour to differ from the default.
If you're looking to convert hibernate objects to XML,you can try hibernate's feature to do that for you. You can provide both mappings in the hbm. Xml itself.
Please see link for more details.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
