JAX-RS Array Serialization Issues

Hi,

I ran into the problem listed at: 
http://cxf.apache.org/docs/jax-rs.html#JAX-RS-DealingwithJSONarrayserializationissues


Is it necessary to set the arrayKeys list for the this to work?  Can I get all 
lists of size 1 to serialize properly?  


Thanks,
-Robert

Yes.

Not without the arrayKeys set.   The basic reason is that we just feed the 
JAXB marshaller an XMLStreamWriter that happens to output JSON.  The writers 
have no idea what they are writing.    They just get events like startElement 
and such.   For any given startElement, it needs to know if it should output 
it as a json array or not.   It's not something JAXB provides to the writer.
