java.lang.ClassFormatError when creating JAXBContext object

[gwinsor]

Hi,
I am trying to marshal an XML document using JAXB 2.0. At runtime,
when my web application tries to create a JAXBContext object, I get
the following exception:

type Exception report

message

description The server encountered an internal error () that prevented
it from fulfilling this request.

exception

Here is the line of code which throws the exception:
JAXBContext jc = JAXBContext.newInstance("com.innatedb.xml.mi");

I am using JDK1.6.0
I have no problem creating XML objects from classes based on the xml
schema and I used the xjc compiler belonging to the JKD1.6.0. In
addition, the java class containing the above snippet of code compiles
without any problems.
Is there anything obvious that I am overlooking? Thanks for any
suggestions you can offer.

Geoff,

Did you solve this one? Looks like the class bytecode being produced
is not a valid Java class. ??? Maybe you can post an XML.
