Re: Re: Providing web services using HTTPS -- RPG400-L

Kevin and Douglas SQL web services functions are not client, there is not
any reason to call it web services function if they were client, on the
other hand FYI sql HTTP functions can retrieve information that you can
consume and can send information that your client can consume (HTTPGET/
HTTPPOST), I have made programs using this that third party java programs
use without any rest or soap configuration. this few links can give you
more detail about those functions and how to use it, the second link maybe
important for you it tells you how to send data using HTTPPOST, hope this
help.

Steps to create a web service on AS/400, test, change the default port to
80**, test, and then finally secure using SSL on the HTTP front end service.

1- Create a new user profile, BRWEB**, copy existing profile
2- Launch IBM Web Admin for i - http://10.x.xx.x:2001
3- Create a Web Services Server, take all defaults.
4- Name the service to match a specified user, matching the user to
the desired environment, BRWEBMIS, BRWEBLIV, BRWEBTRP, etc
5- Fill in description - BRC WEB Service - **
6- To test service, All Application Servers, Manage Details, Using
Test Service tab, test built in ConvertTemp function.
7- Stop both HTTP and Application Servers
8- General server configuration , change HTTP virtual host default
port from 100** to 80**. Each slice needs to use a different port
a. MIS - 8080
b. UP - 8081
c. DevD1 - 8082
d. IT - 8083
e. TP - 8084
f. SP - 8085
9- Manually edit the lwi plug-in from 10052 to 80** - wrklnk
/www/BRWEBMIS/conf/lwi-plugin-cfg.xml (Do not change Transport Host)
10- Application server, Manage Details, Properties, Web Services
Server, change Default WSDL HTTP port to 80**
11- Start both HTTP and Application server
12- Application Server, Manage Deployed Services, using Test Service
tab, test built in ConvertTemp function.
13- Stop both HTTP and Application Servers
14- Using Security tab, turn on SSL on HTTP server
a. SSL - enabled,
b. Server Certificate application name - should match name of Web
service
c. HTTPS_PORT environment variable - should be 1st port on internal
port range of Web Service.
15- Using DCM, system certificate store, Work with Server
Applications, add application.
QIBM_HTTP_SERVER_BRWEBMIS Pencor062010
16- Start both HTTP and Application servers
17- Once SSL is enabled Test Service will no longer function, was
designed to work without SSL, per IBM.
18- To test SSL using built in ConvertTemp, right click on "View
Definition" to get the URL...then paste that into a browser and change http
to https and hit enter, and you should see the xml WSDL file.

I think, we have to configure DCM(Digital Certificate Manager) and, then,
enable SSL option, associate Application ID with SSL option.
Recently I developed web service based on REST, but, unable to try out
with SSL because of missing HTTP group PTFs. We have asked to download
required PTFs and then probably we will be able to deploy SSL enabled web
service

I would love to hear from someone with some knowledge about the

RPG does indeed resolve to the data area for each IN operation. (But if
there had been a previous IN *LOCK, it wouldn't re-resolve until there was
an OUT without *LOCK, or an UNLOCK.)

Here's a little program you can use to test this out. Create a data area
called MYDTAARA *CHAR LEN(10) in QTEMP, with value 'qtemp', and another one
in some other library that's not in your library list, with some value
other than 'qtemp'.

When the command line pops up, add that other library to your library list.

dcl-s mydtaara char(10) dtaara;
dcl-pr qcmd extpgm end-pr;
in mydtaara;
dsply mydtaara;
qcmd();
in mydtaara;
dsply mydtaara;

subject: Providing web services using HTTPS

I am setting up a web service following the methods described by Scott
Klement in his presentation at:

http://www.scottklement.com/presentations/Providing%20RPG%
20Web%20Services%2
0on%20IBM%20i.pdf

I can get everything to work when using http:// but I'd like the traffic
to happen of TLS 1.x instead of plain text. The web service runs on its
own port, not 80 or 443. This works:

http://myserver.com:xxxx/yada/yada/yada

This does not work:

https://myserver.com:xxxx/yada/yada/yada

Nothing in the server instance httpd.conf seems to be related, other than
the listen port of xxxx.

I also can't find discussion of this in the XMLHttpRequest docs at:

https://xhr.spec.whatwg.org/

I can control both the client and server side, so one option would be for
me to do my own encrypt / decrypt (and EBDIC conversion) and pass binary
data instead of trying to piggy back off https support.

But is there a way to have the web service traffic just take advantage of
the HTTPS support?

By default http:// uses port 80. Also https:// uses port 443 by default.

If you're using SSL on a different port, you'll need to specify the port:

https://service.org:4433

subject: RE: Providing web services using HTTPS

You have to config the server side to serve it as HTTPS. It's more than
just changing the URL. In the IBM Web Administrator for i screens, Find the
HTTP server that is serving your web service. You can either select it from
the HTTP Servers tab, or if you go to your server in the Application
Servers tab, there is a link on the left that will take you to your http
server. Click on the Security link on the left hand side once you are in
your http server config page, enable SSL, and fill out all the required
fields. The SSL advanced tab lets your control the TLS versions and ciphers
that you will accept.

Sql has a lot easier way to access resources on the web, its functions
are powerful enough to access and consume data from many sources. for
example httpGetClob retrieve resources from a given URL using the get
method and httpPutClob Create textual resources in a given URL using the
put method, your don't even need to create REST or SOAP services on the web.

I'm not sure that I understand, how does the http clob functions allow you
to provide a web service. I haven't actually used them yet, but they look
