Subject: [EXTERNAL] Re: Problem with proof of concept program utilizing IWS

THe Wizard assigns a port that is currently open on your IBM i. It does
not take into account if your fire wall has that port open and
connectable. If you look at the Manage Deployed Services section in the
Web Admin GUI you will notice a sample services that is created and
shipped. ConvertTemp. A very simple web service that can be used to make
sure that your IWS server can actually be connected to by the outside
world. I have an example service running on the Common1 system, for
example the URL for ConvertTemp on mine
is [1]http://common1.frankeni.com:10213/web/services/ConvertTempService/ConvertTemp?wsdl

That will show you the WSDL file ro that SOAP based Web Service. You can
change the URL using your host name and the port you referenced below. IF
you do not get any response.
You will have to either change the Port number of the server using the
Change port wizard to a port that is available through your firewall. OR,
contact your network administrator to get
that port open.

subject: Problem with proof of concept program utilizing IWS
(Integrated Web Services)

Hi everyone
Before I forget - we are on V7r3
If you are sitting comfortably - then I will begin

I am writing a "simple" proof of concept program, for testing IWS
(Integrated Web Services)
I have created a new service program, with a procedure in it
It has
Ctl-opt PgmInfo(*PCML:*MODULE)
To create the Program Call Markup Language

I have tested the procedure within a program and it works withy no
problems

I followed the following web pages

Creating Web Services With Integrated Web Services
[2]http://ibmsystemsmag.com/ibmi/developer/general/using_iws/

Providing RPG Web Services on IBM i
[3]https://scottklement.com/presentations/Providing%20RPG%20Web%20Services%20on%20IBM%20i.pdf

by Jon Paris and Scott Klement (BOTH HIGHLY recommended)

and I have also used the following web site as well
[4]ftp://public.dhe.ibm.com/systems/support/i/iws/systems_i_software_iws_pdf_WebServicesServer_new.pdf

Following the wizard, I created the web service (creating REST output) and
can start and stop the server from a browser and can see the server in the
QHTTPSVR subsystem

However, when I run the following
[5]http://NBTYS20:10108/web/services/GETCUSTINF/02/882955

in SOAP UI, I get no response
The same is also true in Internet explorer
However, in Chrome, I do receive the following
HTTP ERROR 415

Googling this does not give me much to use

Now - 10108 is the port that was given to this process as part of the
wizard
So I did google
AS400 ports
And found the following web page
[6]https://search400.techtarget.com/tip/How-to-use-NETSTAT-to-troubleshoot-your-iSeries-network-connections

from here I tried the command
NETSTAT *CNN
Which displayed the "Work with IPv4 Connection Status" screen
I then pressed F15, which displayed the "Subset Connection List" screen,
where I can enter the port number (10108) in the
Local port range:
  Lower value .
Pressing Enter (twice), displays Subset of IPv4 Connections showing that
port 10108 is in Listen State
   Remote Remote Local
Opt Address Port Port Idle Time State
   * * 10108 000:00:01 Listen

When I resubmit
[7]http://NBTYS20:10108/web/services/GETCUSTINF/02/882955
from Chrome, and press F5 (Refresh) on the Subset of IPv4 Connections
screen, I get the following displayed
   Remote Remote Local
Opt Address Port Port Idle
Time State
   * * 10108
000:00:01 Listen
   172.31.61.13 57077 10108 000:00:01
Time-wait
   172.31.61.13 57078 10108 000:00:01
Established
   172.31.61.13 57079 10108 000:00:01
Established

This is where I am now - but I don't know where to go to from here
