integrated web services server - IWS

[yuvarajg]

Hi ,

I am trying to consume external web services "http://www.webserviceX.NET/CurrencyConvertor.asmx" in rpg program for currency conversion.

We followed the below steps
1. First generated C stubs using WSDL2SH tool from the WSDL file(attached the WSDL for the reference).
2. Tool generated C stubs Currency.C and CurrencyConvertorSoap.C only (but in Integrated Web service for i help from IBM,it has been mentioned that, it will generate C-stubs for input, port and result.....??????)
3. Created C objects using CRTCMOD using the stubs
4. Created RPG module (attached for reference) to consume web service
5. Created Program by binding RPG module and C module

If we call the program, we couldn't able to get the results , returned XML string is having some junk values. Attached the error also.

Please help us to resolve this issue

Thanks in advance

Re: integrated web services server - IWS

please submit questions in a single thread instead of opening multiple threads for the same question. it becomes unmanageable & is a real pain for those trying to help having to jump through multiple threads, etc.

Sorry for submitting multiple time , since this is the first time I am posting thread in code400, I didn’t realize whether it's submitted or not. I initially thought it was not submitted, so I did again.... Sorry again for the inconvenience

Re: integrated web services server - IWS

You are passing it a currency value of "USD ", and it says that "USD " is not a valid currency. You might try trimming the currency value to remove the blanks and try it again.

Re: integrated web services server - IWS

check the Log file axis.log for the input & output soap message..

Hi Dhanuxp,

Can you help me with the path for Axis.log to check input and output soap messages

Thanks in advance

Re: integrated web services server - IWS

You have to configure..... configurable path is in /qibm/ProdData/OS/WebServices/V1/client/etc/axiscpp.conf

change it as bellow..

# The comment character is '#'
# Available directives are as follows
#
# ClientWSDDFilePath: The path to the client WSDD
# SecureInfo: The GSKit security information
#

ClientLogPath:/tmp/axis.log

Re: integrated web services server - IWS

Thanks for you reply,

In the axis.cpp , its showing the following details only..
# The comment character is '#'
# Available directives are as follows
#
# ClientWSDDFilePath: The path to the client WSDD
# SecureInfo: The GSKit security information
#

how to cofigure to log the errors in that ??

Re: integrated web services server - IWS

edit the file and add following line to end of the file...

ClientLogPath:/tmp/axis.log

then save it.. run your WS client program..
you can see the logs in axis.log file in /tmp directory
examine the request & response message...

how's req/res soap message looks like?

Re: integrated web services server - IWS

Thank you, now i can able to see the log.....
Its send's the reponse and getting it back in XML in log file, but the rpg program, couldnt receive the value properly...

Response in Axis.log file:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><ConversionRateResponse xmlns="http://www.webserviceX.NET/"><ConversionRateResult>55.445</ConversionRateResult></ConversionRateResponse></soap:Body></soap:Envelope>

But in rpg program, the above value is not reflecting, program not receiving proper xml in the string for parsing.

Declared variable to receive the return value as below in RPG program
D xmldoc S *
D xmlstr S 9999A based(xmldoc)

Is that the right way to declare the variable to receive the return value??

Re: integrated web services server - IWS

I've only had a brief moment to look at this, but I think your problem is that your C program is appending a null after the from currency. (inserting a null terminated string into the xml) This is probably why the error says that "USD " is not a valid currency. The currency should read "USD". The blank at the end is likely a null character.

Re: integrated web services server - IWS

Ok. WebService returns correct values. that means your request message is correct...!!!

shall we simplify this ?
can you change your code (inside the monitor statement) like this. Debug it & check what you received to tst_xml variable...

D tst_xml         S           9999A

  Monitor;
		if (xmldoc <> *Null );
             //xml-into currency %xml( xmlstr );
		tst_xml = %str(xmldoc);
		else;
		msg = 'No data..';
		endif;

           On-Error;

Re: integrated web services server - IWS

I tried as you mentioned ,the value in that string:


....5...10...15...20...25...30...35...40...45...50 ...55...60
1 'Ø '
61 ' '
21 ' '
81 ' '
41 ' '

But the C stub returns the proper value "Ret = 7.928500000000E+001" (for currency conversion from USD to JPY), only the RPG program couldnt able to receive.

The declaration is as follows:

D* Pointer to point to string xmlstr which will contain XML doc
D xmldoc S *
D xmlstr S 9999A

Code :

xmldoc = ConversionRate(CurCnWS:'USD':'JPY');

// ************************************************** **
// ************************************************** **
Monitor;
if (xmldoc <> *Null);
xmlstr = %str(xmldoc);
else;
msg = 'Conversion Error';
endif

I think some problem in the declartion to receive the parameter. can you please help to fix this issue

Re: integrated web services server - IWS

I cant repost your initial error screen, but look at it again. The error says that 'USD ' is not a valid value for a currency, and its not. It must be 'USD'. The error is likely the C program, which is probably writing a NULL terminated currency code string into the XML.

Re: integrated web services server - IWS

yes some problem with the C-program, its adding null at the end of To currency, i was using %addr for passing the parameter to C program. Now i changed it by sending directly the parameters as shown and its working fine


xmldoc = ConversionRate(CurCnWS:'USD':'JPY');

Thanks michael.
