RE: Attempting to learn Web Services (by example) -- RPG400-L

John,

From your prior post:

snip>
The Location value shows as
Location:
http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.p
hp
/snip>

Again, From your prior post:

snip>
SOAPAction:
http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.p
hp#LatLonListZipCode
/snip>

comparing snip 1 to snip 2, it appears snip 1 is possibly a truncated URL

And, when I enter the URL from snip 2 in my browser, I get a web page

Ah, looks like you may have had a truncated URL - good luck!
(and I hope to be doing as you are as time permits)

Gary,

Thanks for the suggestion, I will test with the change you suggest

The Location value shows as
Location:
http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.p
hp

I am completely new at this, would I change the SOAPAction

From

SOAPAction:
http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.p
hp#LatLonListZipCode
To
http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.p
hp#LatLonListZipCode

John

John,

I am way out of my depth, but your destination URL needs to be changed to the "URL provided in the Location field of the response"

Maybe you already knew that - and I don't see the "Location field" in your post, so I'm no help with that . . .

when I enter
"http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndfd";
in my browser, I get web page not found

HTH

I thought I would come into the office today and see if I could learn Web Services (by example).

I am trying to use Scotts Example Program LOCWEATH

Any help or pointers would be greatly appreciated

CALL LOCWEATH PARM('30097')

Compiles Fine

I can ping to the www.weather.gov

HTTP is up and running

I am trying this on IBM i 6.1

When I run the program I get error - HTTP/1.1 301 Moved Permanently

(I have included the log file below)

Running in Debug I see the program gets to the NOAA_LatLonZipCode procedure

Variable SOAP =

....5...10...15...20...25...30...35...40...45...50...55...60

1 '<soapenv:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchem'

61 'a-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xml'

121
'ns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns'

181
':ndf="http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndf
d'

241 'XML.wsdl"> <soapenv:Header/> <soapenv:Body>
<ndf:LatLonListZ'

301 'ipCode
soapenv:encodingStyle="http://schemas.xmlsoap.org/soa'

361 'p/encoding/"> <zipCodeList
xsi:type="xsd:string">30097</zipC'

421 'odeList> </ndf:LatLonListZipCode> </soapenv:Body>
</soapenv:'

481 'Envelope>
'

Then when http_xproc( HTTP_POINT_ADDL_HEADER

: %paddr(SoapActionLL) );

Is executed it appears to run ok

Then when rc = http_url_post_xml(
'http://www.weather.gov/forecasts/xml/+

SOAP_server/ndfdXMLserver.php'

: %addr(SOAP) + 2

: %len(SOAP)

: *NULL

: %paddr(endTag)

: %addr(LatLon)

: HTTP_TIMEOUT

: HTTP_USERAGENT

: 'text/xml');

Is executed rc=301

and http_error(errnum);

if (errnum<>HTTP_XMLERR or x=15);

http_crash();

endif;

causes the eventual error HTTP/1.1 301 Moved Permanently
