Ah, ok. The xml and schema were obtained on separate occasions from another
company, so I wouldn't be at all surprised if there was a mismatch between
the two. I tried changing the elementFormDefault but that didn't seem to
fix it.
The package-info.java, I'd forgotten about that, but my compiler (JBuilder)
complains
"package-info.java": package annotations should be in file package-info.java
at line 8, column 1. Which seems a little odd, and I had been ignoring the
error and running the program anyway....the file looks like:-
// auto-generated comments
@javax.xml.bind.annotation.XmlSchema(namespace =
"
http://www.T45PCO.com/combat_system/encyclopaedic_data",
elementFormDefault=javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package odc_jaxb_gen;
The OdcStoreDataT doesn't have an XmlRootElement annotation when it is
automatically generated, but this is the only annotation I have written
myself, and I have tried specifying both an empty namespace and the actual
namespace without success.
So if I managed to get package-info to compile, do you think this would then
work? The package name odc_jaxb_gen is supplied in the call to xjc.
Thanks,
Sean

Subject: RE: namespace query
The error does indeed not match your schema. I have four interpretations to
offer:
* you compiled against a different schema (maybe with
elementFormDefault="unqualified")
* you missed a generated package-info.java that states the namespace for all
classes
* you wrote the annotations yourself and forgot to add a namespace to the
XmlElement annotation on the header field
* it's a bug in JAXB
