RE: Invoking a Web Service from an i5

Just use the HTTPAPI at http://scottklement.com or GETURI from
http://bvstools.com in your RPG program.  Note that these don't have
utilities like wsdl2java like Axis does, so you are left to compose your own
SOAP, but none the less it is very doable and I have done it.

If you want to have good performance I would stay away from having RPG talk
with Java directly because of the JVM overhead.

Subject: Invoking a Web Service from an i5

Hi All:

 

Has anyone tried ever tried invoking a Web Service from the AS/400 using RPG
ILE?  My thought is that I could stick the Apache Axis jar into the IFS,
write a Java client to import the necessary Axis classes to invoke a Web
Service, then prototype the class in an ILE procedure and invoke it to get
the response back to the RPG program.  The reason I need to do this is
because I need our RPG based OMS system to initiate the request.


 

My question is will sticking the Apache Axis jar on the AS/400 be enough?
We have no application server running on our 400.  Is an http server
required for a client to invoke a web service or does Axis use sockets to do
such?  Would it be better to just do the socket programming inside the RPG
app?  

 

Thanks a million to anyone who can help me on this issue.

 

Sincerely,

Andy
