I am not sure it's strictly true to say it has its own web server - you'dhave to put some code together yourself - but you'd be better off making
use of something like express.js.
I am not sure I follow the first part of your question. The web server
embedded/included with Node.js is here:
http://bit.ly/nodejs-12-http_createserver ExpressJs is a facade that uses
the embedded/included web server. Further, here's the actual net.js code:
https://github.com/nodejs/node/blob/master/lib/net.js
And with the 'cluster' npm you can easily load balance between multiple
processes (IBM i jobs). Here's some sanitized sample code I wrote for a
Node.js-on-IBM-i customer. Basically the 'rpg' module contains calls to
RPG using the iToolKit.
var http = require('http');
var rpg = require('./rpg')
var app = require('express')()
var cluster = require('cluster')
if (cluster.isMaster) {
for (var i = 0; i < 2; i += 1)
cluster.fork()
} else {
process_request()
}
function process_request(){
app.get('/getprice', function (req, res) {
rpg.pgm1(req.query.myparm, req.query.myparm2, function(output){
res.send(output)
})
})
}
http.createServer(app).listen(8080)
console.log('Listening on port %d', 8080)

What language do they use?
<vendor>
If RPG, check out RPG-XML Suite: rpg-xml.com
</vendor>
If they're open to non-RPG options then things like Node.js make it dead
simple to do web services (no Apache/Tomcat config necessary, Node.js
includes its own webserver).

Folks:
I have a customer that is about to take the plunge into web services.
offirst need to choose if they use WAS 8.5 Express, IWS or TOMCAT. Some
implementation.the IBM i instances have the Zend server so they would use that when
available. Next they need a good primer about design and
hasI've found the basic web sites from IBM but I'm wondering if the group
potentiallysome suggestions on best practices and resources to use.
The customer is at V7R1 now but will be at V7R2 very soon and
relatesV7R3 by end of year. Any comments on the IBM i environment as it
expertto
web services would be welcome as well.
While I can build and deploy a simple web service, I am far from an
listtherefore my request to you.--
