Re: Creating an RPG web service without WDSC/RDi

[Bent Rønne <ronne@xxxxxxxxxxxxx>]

Mike,

Why not just call a RPGLE Web Service directly?

IceBreak lets you create SOA (Service Oriented Architecture) Web Services
from any RPG service program in few easy steps.

* Set the compiler directive type="webservice".
* Set the "export" keyword on the function you want to populate.
* Use the IceBreak extended keywords Input, Output or InOut on the parameter
list.
* Suffix your source file with the .asmx extension.

When you refers to the Web Service from the Browser URL IceBreak will:

* Compile the RPG program into a service program
* Create a source file QSOAPHDR with prototypes for your functions, so you
can reuse them in a non SOAP environment.
* Build the SOAP wrapper functions for your exported functions (They have
the same name suffixed by an "_")
* Build a WSDL file that describes how to invoke the webservice

A simple RPG web service could look like:

 
<%@ 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
%>
 
This sample takes x and y as input parameters and calculates the sum z.
As you can see - it is pretty much a normal service program except for the
input/output keywords in the D-Spec.

Basically it is a normal service program with no mainline. It simply exports
a number of procedures. You are not restricted to only one.

So with this technique you can interface the outside world directly with
your RPGLE :o)


I hope that this input can give you an idea.

Regards

Bent Ronne

Subject: [WEB400] Creating an RPG web service without WDSC/RDi

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
