RE: Invoking a Web Service from an i5

Andy...

Consider using JT400 within a java application to send and receive data
queue entries. This avoids the JVM throughput issues created by having
the RPG program call the java classes directly since the java
application is running constantly waiting on data queue requests.

I use WDSC to generate the Web Services and invoke the methods once a
data queue entry is received. I then supply the results back to the RPG
program through the same data queue. Using a keyed data queue with
unique key values allows for transaction integrity and scalability.

Hope this helps,

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
