rajs How to call webservices,Guide me
Hi,I am not able to call the webservices which is exposed by our client.I have used webservice callout and http protocols but not working.
can you guide me ?
What I have tried ,
My services are living here 'https://www.criminalbackground.com/HRXMLWebServiceTest/Service.asmx'
Http h = new Http(); HttpRequest req = new HttpRequest(); String url= 'https://www.criminalbackground.com/HRXMLWebServiceTest/Service.asmx'; req.setEndpoint(url); req.setMethod('POST'); req.setHeader('content-type','text/xml'); req.setHeader('SOAPAction','GetPackages(userId,password)'); HttpResponse res = new HttpResponse(); res= h.send(req); //code ...
how to call the 'getpackage(String UserId,String Password)' method from our apex class.
Please give some example code other than sfdoc examples which will be helpful to us.
Thanks,
Raj

Okay, here's your code... create the class below. Actually, I recommend that you read the docs, and you'll see how easy it is to generate the following class from your WSDL.

After this, go to Setup > Remote Site Settings and add a new remote site having URL https://www.criminalbackground.com and you're all set.
Once you've created the class above and added the site, here's the code to call the web service:
String username = '<USERNAME>';
String password = '<PASSWORD>';
CriminalBackground.ServiceSoap port = new CriminalBackground.ServiceSoap();
String result = port.GetPackages(username, password);
Hope this helps!

BTW, here's the link to the docs that will help you create classes to callout to webservices:

Hi Soof,
Thank you for your great guidance.Now I able to explore the webservices.The way you approached is so understandable.I tried your code to call the getpackages() method,I got the following error
System.CalloutException: IO Exception: Read timed out
Class.CriminalBackground.ServiceSoap.GetPackages: line 50, column 13 Class.criminalBackgroundVF.getContents: line 43, column 17 External entry point
for your reference Line No:50 is WebServiceCallout.invoke() in getpackage method.and also tried the variable 'timeout_x' to set the maximum time out limit(60000 ms).
can you please tell me where I made mistake
Once again I thank you,
Raj
