Re: samples json : "com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character '{' (code 123) in prolog; expected '<'"

The next release will include improved json docs and a few bug fixes,
as this is the direction my day job has moved into for some time now.

What I suspect is your problem, is that you need the right axis2.xml
file config that supports json. Its setup for SOAP by default.

Here's how mine looks. Note that I use one config for SOAP and another
for json via build time tweaks of the file
