RE: New to http questions
Walker,
Two questions...
1. Do you have debug turned on in the RPG program? Example 18 has it turned
on. If you took it out, put it back in (http_debug(*ON);). If you have it,
then you can look in the IFS in /tmp (wrklnk '/tmp/httpapi_debug.txt'). Copy
the entire file to your email and send it out.
2. Can you run the web service from some other interface? Such as straight
from IE. If you can, post the code that you use to test that the service is
working.

Good morning, Mr. Klement. Well I am no longer getting a 404. Now the
message is:
"CommTCP_read: recv: A connection with a remote socket was reset by that
socket."
I surmise that I am not making a connection, or maybe I am but not passing
the correct connect info? I really hate that I am ignorant about this, so
if you have a small clue, I would appreciate it. What I really don't like
is my inability to debug the whole process!

Hi Walker,
I guess I would do the SOAP message a little differently. I'd create a SOAP
message that looks like this:
soap = '<?xml version="1.0" encoding="iso-8859-1"'
+ ' standalone="no"?>'
+ '<soap:Envelope '
+ ' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>'
+ '<soap:Body>'
+ ' <tns:processLoad '
+ ' xmlns:tns="http://services.prealert.hwy.pgl";>'
+ ' <loadInfo>' + %trim(AlertData) +'</loadInfo>'
+ ' </tns:processLoad>'
+ '</soap:Body>'
+ '</soap:Envelope>';
Don't forget to encode your "AlertData" if it contains any special XML
characters (less than, greater than, ampersand characters).
Also, you'll note what the WSDL says for SoapAction:
<wsdlsoap:operation soapAction=""/>
See? It shows the SoapAction as a blank string.... so you should also tell
HTTPAPI to set a blank string (in the last parameter to
http_url_post_xml)
rc = http_url_post_xml(
'http://172.30.30.20/PreAlertWebServices/services/PreAlertServices'
: %addr(SOAP) + 2
: %len(SOAP)
: *NULL
: %paddr(Incoming)
: %addr(status)
: HTTP_TIMEOUT
: HTTP_USERAGENT
: 'text/xml'
: '' );
Good luck!
