Intriguing way to make any rpg programmer into a web service developer, wrap the normal rpg with the extra snippets and compile

Hi Mike;
I think you will find some overlaps in implementations of web-services using
RPG.
Besides to make a JSP/JAVA webservice using RDI running under WebSphere you
have other posibilies:
One way is to use the PHP. You create the webservice in PHP and call your
RPG application using the PHP toolkit, where you can call any ILE program.
Also I know that you can find a more native solution near Aarons heart at:
http://www.rpg-xml.com
And finally ... I have to go into vendor mode .. is IceBreak
IceBreak is using "annotations" into the RPG syntax which make RPG the only
language you need to define and code a web service...
Annotations are heavily used in C# and even more in NetBeans to extend
native languages to support and expose webservices.
Take a look at this tiny calculator webservice in RPG using IceBreak :
<%@ language="RPGLE" pgmtype="webservice" %>
<%
h nomain
p*name++++++++++..b...................keywords++++++++++++++++++++++++++comm
ents++++++++++++
p Calculator B export
d Calculator pi
d x 10i 0 Input
d y 10i 0 Input
d z 10i 0 Output
/free
z = x + y;
/end-free
p Calculator E
%>
The "pgmtype=webservice" causes the precompiler to build a ILE service
program, and the "export" let it be exposed as an web-service.
The rest is just a normal service program - exept for the "annotation" on
the parameter namely "input" / "OutPut" and "InOut".
Look at it as keywords which is not allowed in the normal RPG syntax.
However these "annotations" causes the SOAP envelop to be created and a
WSDL file to be produced ..
A consequence; all RPG service programs in IceBreak is actually also
webservices .. think about that . The guys down at first have made a good
job :-)

Is there a way to turn an RPG stored procedure into a web service without
using WDSC/RDi? Maybe by using an existing web service that calls RPG as a
base and cut/paste/rename/edit the files in the IFS manually? Someway that
does not have the added overheard of needing to learn WDSC/RDi just to do
that final step after the rpg app has been created and tested
