Re: Web services primer -- WEB400

I'm certain there is a version of WAS available just about anywhere (but not
included with the OS like it is with IBM i ) but that's a moot point for our
discussion anyway.

There is not a current need to be platform independent, DB/2 is the single
source of truth in this case and it runs on IBM i. Neither is likely to
change in the near/mid-term. Long term changes would result in a
significant change anyway so I'm not concerned with what that would add to
that effort for this choice. For now cheaper and easier to provide a solid
series of web services is needed. We'll do the work to make them solid, but
the less that needs to done from a system administration perspective the
better. IAS/IWS is looking like the primary choice right now do the
capability and ease of implementation. On the other hand Scott's code
looks too easy.

Bob, are you sure that's right. I am fairly certain WebSphere is available
on LUW also. i.e.

Jim,

Tim Rowe has some good points, but WebSphere locks you into the IBM
platform. If you use Tomcat or JBOSS your are 100% flexible and

Do they get to choose what data format they'll use (soap, xml, json,

etc?)

If so, the YAJL port would be sweet if it interfaced with ILE COBOL

which it

most likely does... building JSON is a breeze.

The apache server already does all the job/thread control, no need
to

stack

things (although I do enjoy node.js.. just seems like they're just

rewriting

everything that is already available.. thus a "stack"). I do so
enjoy node.js so far, though.

I think of node development as a "reverse onion". Instead of
peeling

back

layers, you add them as you go along in your development. Maybe one
of those balls that's made out of rubber bands... would be a better

explanation

:) But it sure is fun!

Tim,

Quick question that I've never thought about since none of my
customers
currently use IWS outside of the automatic IBM supplied items. .

know to
update the WAS Express 8.5 we run a program at the command line
or

in

the
*ADMIN server to apply the service pack after the PTFs are

installed.

Does the IWS server get updated with just PTFs or is there an
additional
step there too?

Correction time. WebSphere is not a thing of the past, and
on IBM i
it
is
included with your operating system license. Now, I would not
necessarily use full blown WebSphere when starting out with Web
Services.
There are many other options that the IBM i programmer will

find

easier
to consume then doing the heavy lifting them selfs.

The Integrated Web Services (IWS) support is part of the IBM
i

OS,

supported on 7,1 and higher. Allows for SOAP or REST based web
services.
Web Site - [1][2]
http://www-03.ibm.com/systems/power/software/i/iws/

Get the latest DG1 PTF Group and you have the most current
support (
on
any supported release) This support leveraged the Liberty web
container
along with JAx-WS and JAX-RS. The Web Admin GUI interface
gives the
IBM
i
programmer a super easy way to create and host their Web

Services.

Jim,

Spend some time at Apache.org and take a good look at
Tomcat or go
look
at JBOSS both are free open source servers. WebSphere is
virtually
a
thing of the past. It makes no sense to spend the money on
WebSphere
today.

Folks:

I have a customer that is about to take the plunge into web

services.
They

first need to choose if they use WAS 8.5 Express, IWS or

TOMCAT.
Some
of

the IBM i instances have the Zend server so they would use

that

when

available. Next they need a good primer about design and

implementation.

I've found the basic web sites from IBM but I'm wondering

if the
group
has

some suggestions on best practices and resources to use.

The customer is at V7R1 now but will be at V7R2 very soon and

potentially

V7R3 by end of year. Any comments on the IBM i

environment as it
relates to

web services would be welcome as well.

While I can build and deploy a simple web service, I am

far from
an
expert

therefore my request to you.
