Web Service Properties

You can modify an object's properties from its property sheet. To open a web service property sheet, double-click its Browser entry in the Web Services folder. The following sections detail the property sheet tabs that contain the properties most commonly entered for web services.

The General tab contains the following properties:

Property	Description
Name	Name of the web service. Used in URIs to access the web service. It can neither start with a slash nor contain two consecutive slashes
Code	Code of the web service
Comment	Descriptive label for the web service
Stereotype	Sub-classification used to extend the semantics of an object without changing its structure; it can be predefined or user-defined
Local path	Name prefixing the web service. If you type a path, the User-Defined tool (beside the Local path box) is pushed-in. Click the User-Defined tool to recover the original path. The default value is the name of the web service
Service type	[ASA, ASE, and IQ only] Specifies the type of web service. You can choose from: DISH - [ASA and IQ only] acts as a proxy for a group of SOAP services and generates a WSDL file for each of its SOAP services. When you create a DISH service, you must specify a prefix name (on the Extended Attributes tab) for all the SOAP services to which the DISH service applies. PowerDesigner treats SOAP web services as Web operations (see Web Operations (PDM)) of DISH web services. HTML – [ASA and IQ only] the result of the SQL statement or procedure is formatted as an HTML document (with a table containing rows and columns). RAW - the result of the SQL statement or procedure is sent without any additional formatting. SOAP - [ASE only] generates a WSDL (Web Services Description Language) file. XML - the result of the SQL statement or procedure is sent in XML. By default, the result is converted into XML RAW format.

Security Tab

This tab is available for ASA/SQL Anywhere and IQ only, and displays the following properties:

Property	Description
Secured connection	If selected, only HTTPS connections are accepted. If cleared, both HTTP and HTTPS connections are accepted
Required authorization	If selected, all users must provide a name and a password. When cleared, a single user must be identified
Connection User	When authorization is required, you can select <None> or a list of user names. When authorization is not required, you must select a user name. Default value is <None>, which means all users are granted access

The following tabs are also available:

Operations - Lists the Web operations associated with the Web service (see Web Operations (PDM)).
Sybase - [ASA/SQL Anywhere, ASE, and IQ] Includes Sybase-specific properties (see Sybase SQL Anywhere)
Namespaces - [IBM DB2] Lists the namespaces associated with the Web service, including their prefix, URI and a comment. An XML Schema can be specified where elements and data types used in web parameters and result columns are defined.
