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.

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_1:8080/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:
|
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.
