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

John,

My copy of LOCWEATH was already modified for the changes in the NOAA's web service back in September 2011. I don't know what the old copy looks like anymore, so I can't tell you which lines to change.

In an attempt to help you, I've put the new copy here:
http://www.scottklement.com/rpg/Weather.zip

Take a look, and maybe you'll see what I've changed.

Scott,

I have looked at this web page and all the links
Unfortunately I am new at this web services stuff (trying to
learn by using your example program LOCWEATH)

So I did go to this web page and looked at all the links and
it doesn't help me the newbie.

I changed what I though needed to be changed but I get the
same error :(
Can you tell me what line or lines in your program LOCWEATH
would need to be changed and what they need to be changed
to?

Once I get the program working then I think I can play
around with it and learn better (I prefer learn by example
method)

Thanks in advance for all your help

It would appear that the web service has moved to a
different server. A quick Google finds this page with all
the details:
http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.p

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
