Web Service Example 1: Define a Web Service Provider

This topic is the first part of Web Service Example 1: RPC-Oriented Method with Simple Type Parameters

To define the web service provider:

1.	In the Web Services (Provider) window, define a TRAVELSERVICE web service provider.

2.	On the Methods tab page, define a GETTOURS method, set the Operation Style to: RPC-oriented, and set the Method Call to: Synchronous.

3.	Define SQL statement:

SELECT *

FROM tour

WHERE destination = :destination

AND tour_type = :tour_type

4.	Click the Check button, and in the Question dialog, click Yes.

All input and output parameters are generated. Parameter names are unique (case sensitive): there can be two different destination and DESTINATION parameters. USoft determines the XML Data Type of all parameters automatically.

The order of the parameters is the order in which the bind variables appear in the SQL statement. This may not be the order in which you want to think of, or expose, the parameters in the web service. If necessary, check and re-arrange the order of parameters.

5.	On the Details tab page, specify all Rules Service and Web Service Files settings. For example:

Application: TRAVEL

User: TRAVELUSER

Password: traveluser

Host Name: MyWebServer

Port Number: 7777

Access Point File: C:\inetpub\wwwroot\TravelService\TRAVELSERVICE.asp

Access Point URL: http://MyWebServer/TravelService/TRAVELSERVICE.asp

WSDL File: C:\inetpub\wwwroot\TravelService\TRAVELSERVICE.wsdl

WSDL URL: http://MyWebServer/TravelService/TRAVELSERVICE.wsdl

Target Namespace: http://MyWebServer/TravelService/TRAVELSERVICE.wsdl

6.	Save your changes.

7.	Click the Create Web Service button.

The web server publication folder now contains a TRAVELSERVICE.xml, TRAVELSERVICE.asp file, and TRAVELSERVICE.inc file.

8.	Click the Create WSDL File button.

The web server publication folder now contains a TRAVELSERVICE.wsdl file.

9.	Start a Rules Service for the TRAVEL application that is accessed by the web service provider on port 7777.
