Jaxb char mapping

[Marco Piraccini]

I'm using CXF with jaxws and jaxb. My problem is that the "char" java  
types are mapped to xs:unsignedShort (instead of xs:string with size 1  
as i expected).

I read the jaxb 2.0 specs, but the char primitive type mapping seems  
not to be defined.

There is a quick way to configure/customize jaxb to map char to xs:string?

Bye,

Marco.
