JAXB Content not Instantiating

Ok, I am at a loss. I am having a Null pointer on this line:

    JAXBContext             context         = JAXBContext.newInstance( X3D.class );

And here is the output error thing:

Exception in thread "main" java.lang.NullPointerException

I realize that not all the code is there and I can add more but if I understand correctly, this command setups stuff and is not at all dependent on any of my other variables. And it was working and then just stopped. I don't know why.

It says over and over again "Unknown Source" but I include the path and class X3D so that it should be fine.

Thanks.
