JAXB cannot unmarshall and previous posts do not seem to be related

Question

Hello,
Recently, we had to change some of our XSDs, so I went and downloaded the latest Java web services pack (v1.6) and made the changes to the schema (only one new element). First, I realized we were using a 0.75 EA1 release of JAXB and that I would have to re-generate all the classes for all our current XSDs because of 0.75 is so outdated.
I regenerated all the classes and everything seemed to be in good order. When I started my application I received the following error (this is in jdk 1.5)
Now, the XSD and the XML have not changed in 3 years... why is it that using this new version of JAXB seems to have messed things up? This errors is received when trying to unmarshall. I have been looking at this for three days and reading all the posts, i don;t think this is a namespaces issue because it used to work.... i just don't get it. any help is GREATLY appreciated.
Thanks

Answer 1

have you tried it with only 1 complexType in the xsd with the element?
I have an xsd with many complexTypes and found that the root element was not what i thought it was (ie in your case ConfigInfo) and was having to append an xml tag at the start and end.
Don't know if it's something to do with the new version of JAXB as the one with 1.6 is the only one i have used...
