Call-in and Call-out to webservices

Things to take care of, before you start

- Install MSSoapToolkit on the server
- Add Soap driver in the asn file:
Uniface ASN file SOURCE CODE
Sorry- ... please log-in or register to get this!


A few steps to get imported webservices running

1. Import the wsdl file
... using /Sti /mwr=ws http://server/path/service.wsdl in the prompt while launching Uniface. For example /Sti /mwr=ws http://soatest.parasoft.com/calculator.wsdl

2. Compile the generated signature.
Check if the properties of the signature are correct. Further take a look at the the methods and parameters of each one.

3. Update udesc.urr using /urr

4. Make a simple form and Test it!
Example: The webservice "calculator" has varios methods, one of them is "add" that have 3 parameters (param1 OUT,param2 IN,param3 IN) so the form could have the instruction: activate "calculator".add(vnresult,vnparam1,vnparam2). Obviously the webservice returns vnparam1+vnparam2 in vnresult.


Generate a webservice:

1. Write the service that have to execute the server
1.1 Check that it works as a normal service.
2. Generate wsdl file using /sto /mwr=ws servicename
3. Copy wsdl file to tomcat in \webapps\uniface\WEB-INF\wsdl
3.1 Start Tomcat and check that the serviceweb is visible.(e.g. http://server:8080/uniface/services/servicename?wsdl)
*Be careful with web.xml file, check SRD servlet.
4. Update udesc.urr using /urr

If all is correct, the webservice works.

Frecuently problems and issues

-50 Signature not found.
Solution: update urr, check web.xml, urouter.asn files and asn file of userver.

-81 Failure to connect to engine.
Solution: Check signature properties.

-150 xxx yyy zzz
Its a generic error, most of the time are wrong parameters.
Solution: Check null parameters or wrong soap address, check wsdl file and signature properties.

With Uniface 9, to get the same web service definition, you have to indicate you want the old RPC encoded style : /sto /mwr=ws /rpcencoded servicename Otherwise, youll get the Docment Wrapped Literal (dwl) style. Also, using SOP 2.0, you dont need the MS SOAP toolkit anymore.
