Re: RPG & webservice

So, one other idea that would still use CGIDEV2 (I could easily pull it 
off with Java...my comfort zone...)

So, you do your magic with Scott's YAJL and either write it to the IFS 
or hold the output in memory.  I think that CGIDEV2 can read in a file 
from the IFS, any text file, your file in JSON format.  So, you read 
that file in and then output the entire contents with the WrtNoSection 
subprocedure.  You may want a file that has a minimal header with 
something like

/$top
Content-type:application/json
Expires: 0

so that the file is written with the correct content type....seems like 
that would be simple and would work.....

If I get a chance I'll whip up a proof of concept...RPG and CGIDEV2 
aren't my strong suits but cobbling stuff together is  :-)
