Generating WSDL

Web service definition language (WSDL) is the XML file that stores the metadata used to describe your Web service, defines service endpoints, and publishes information about your Web service. WSDL helps automate the generation of client proxies for Web services in a language-and platform-independent way. Like the IDL file for CORBA, a WSDL file provides the framework for client and server communication.

Generating the WSDL

From a project or Package Explorer, highlight the package that contains the Java file for which you are generating WSDL.

Right click the file and select Generate WSDL.

The Generate WSDL wizard displays. Table 4-7 describes the Generate WSDL properties. Complete the information and click next to move to the next window and Finish when done.

**Table 4-7: Generating WSDL wizard options and properties**
Window	Property	Description
General options	Web Service Name	The Web service for which you are generating WSDL.
	Location URL	The location where the Web service is available.
	Target Namespace	A valid Uniform Resource Identifier (URI) for the location where the WSDL document is published. The target namespace should not include the file name; WST appends the appropriate file name when the WSDL document is generated. The target namespace can be a Uniform Resource Name (URN), which is a globally unique and persistent URI. `http://www.com.sybase.webservices` is an example of a valid URI. `urn:simpleJavaClass.test` is an example of a valid URN.
	Port Type Name	Describes a collection of operation elements that define the abstract interface of the Web service. The port type name provides a unique name among all port types defined within the WSDL document. For example: <portType name="SimplePortType">
	Binding Name	Contains the details of how the elements of the Port type name are converted to a concrete representation of the Web service by combining data formats and protocols: <binding name="TestBinding"
	Service Port Name	Indicates the Web service endpoint address. For example: `http://EAServer_1:8000/webservices/testPort` or `testPort`
	Implementation Class	The name of the class file implementing the Web service.
	Type Mapping Version	The type mapping version. Valid options are 1.1 (the default) and 1.2.
	Soap Action	The URI for the SOAPAction HTTP header for the HTTP binding of SOAP. The SOAPAction HTTP request header field can be used to indicate the intent of the SOAP HTTP request. The URI identifies the intent.
	Binding Style	The SOAP binding style: Document – indicates that the SOAP body contains an XML document. RPC (remote procedure call) – indicates that the SOAP body contains an XML representation of a method/operation call. Wrapped – a document literal variation, that wraps parameters as children of the root element.
	Soap uUse	The SOAP body use: Literal – if using a document binding style. Encoded – if using an RPC binding style.
Method Selection	Method nName	Select the methods/operations of the Web service for which the WSDL is to be generated.
Location	File Location	The location and file name (ending with .wsdl) of the generated WSDL file.
