Creating Web Service Destinations

To establish connections to servers that contain web services, you must create Web service destinations. You can create three types of Web service destinations based on your requirements, as explained in the following table:

Requirement	Destination Type
You need the client application to locate and access the Web service on the provider system through the corresponding WSDL file. In this case, the entire provider system is considered to be a single Web service.	WSDL
You need the client application to locate and access the WSDL of the corresponding Web service through the WSIL file.	WSIL
You want the WSDL of the corresponding Web service to be published in a service registry. The client application must locate the WSDL file by querying the service registry.	Service Registry

Prerequisites

You have obtained:

Authorization to connect to a server and to access the required Web service.
URL of a Web service.

Procedure

Creating a WSDL / WSIL Destination

Choose Window Preferences.
In the Preferences tree, expand the Destination Configurations node and choose Web Service Configuration.
In the Web Service Configuration screen area, choose Create.

In the Create Destination window, specify the destination and authentication details as explained in the following table.

Field Name	Description	Value
Destination Name	Name of the physical destination of a provider system. This name must be identical with the name of the logical destination in the client application	A meaningful alphanumeric text
Destination Type	How the system has to search for a Web service	`WSDL` or `WSIL`
WSDL / WSIL URL	URL of the destination type	If you have chosen WSDL, enter the direct link to the WSDL file on the provider system. If you have chosen WSIL, enter the direct link to the WSIL file on the provider system. Example For the AS Java system, enter `http://<host_name>:<port>/inspection.wsil.` For the AS ABAP system, enter `http://<host_name>:<port>?sap-client=<client number>` End of the example.
Socket Timeout	When the connection to the provider system has to be closed	The default value is `60,000` milliseconds
Authentication Required	Determines if an authentication to access the destination is needed	Select or deselect the checkbox
User ID	Name of the user through which the system can connect to the required destination of the provider system	A username assigned to you
Password	The corresponding password through which the system can connect to the required destination of the provider system	A password assigned to you

Choose Finish.
Choose OK.

Creating a Service Registry Destination

Choose Window Preferences .
In the Preferences tree, expand the Web Services node.
Choose Services Registry.
Enter the server name and the server port for the UDDI and classification service.
Choose Apply.
In the Preferences tree, expand the Destination Configurations node and choose Web Service Configuration.
In the Web Service Configuration screen area, choose Create.

In the Create Destination window, specify the destination and authentication details as explained in the following table.

Field name	Description	Value
Destination Name	Name of the physical destination of a provider system. This name must be identical with the name of the logical destination in the client application	A meaningful alphanumeric text
Destination Type	How the system has to search for a Web service	`Services Registry`
System Type	Type of the provider system	`Java` or `ABAP`
System Name	System ID of the provider system	An alphanumeric system name, for example, `U7A`
Host Name	Name of the database host of the provider system	An alphanumeric host name, for example, `us4296`
Installation Number	Installation number of the provider system	A numeric value, for example, `0120021077`
Client	Number of the AS ABAP client in which the Web services are available	A numeric value, for example, `000`
Socket Timeout	When the connection to the provider system has to be closed	The default value is `60,000` milliseconds
Authentication Required	Determines if an authentication to access the destination is needed	Select or deselect the checkbox
User ID	Name of the user through which the system can connect to the required destination of the provider system	A username assigned to you
Password	The corresponding password through which the system can connect to the required destination of the provider system	A password assigned to you

Choose Finish.
Choose OK.

Result

The Web service destination that you have created is available for search in the Visual Composer Search task panel on relaunching Visual Composer.
