Subject Axis2: JSON support and compilation Errors from latest SVN
Date Wed, 21 Mar 2007 14:37:08 GMT
I came across the latest feature of Axis2 allowing JSON. As I am looking
at building out my site to inculde AJAX I was interested in trying this
out. I was trying JSON with the latest Snapshot of Axis2. I was looking
at trying out the Sample application YahooJSONSearch, however I ran into
the following error when running it from the latest binary snapshot:

I decided to try and checkout the source from SVN to determine if that
might help in fixing the error. When running Maven to compile the Axis2
code I recieved the following error:

My question is two part, first if there is anything I may be doing wrong
that would generate the errors. Second when is an expectated release
with JSON going to be release as Stable. I appreciate any help you may
provide.
