WSIF Bindings

How to create a WSIF WSDL?

Add these two schema to your definitions tag
xmlns:format="http://schemas.xmlsoap.org/wsdl/formatbinding/"
xmlns:java="http://schemas.xmlsoap.org/wsdl/java/"

The format namespace adds support for mapping Java types to XML schema.
The java namespace allows mapping WSDL operation to Java methods.

Specify binding Information
<binding name="JavaBinding" type="tns:TestService">
<java:binding/>

Binding name specifies the name which would be reffered from service tag.
Binding type specifies the portType, specified in WSDL
The java:binding tag identifies that this is bound to Java code rather than a SOAP service.

This binding would encompass, formatting information, i.e. which XML tag is to be mapped to what Java DataType

<format:typeMapping encoding="Java" style="Java">

The format:typeMapping tag tells us that we will be mapping XML Schema types onto Java types.

<format:typeMap typeName="xsd:string" formatType="java.lang.String" />

The format:typeMap tag explains what Java type is to be used for each XML schema type in the interface.

The Service Tag refers to binding tag for mapping information.
The Java:address tag specifies fully qualified classname which contains implementations of operations specified inside binding tag.

<service name="TaskServiceService">
<port name="TaskServicePort" binding="tns:TaskServiceWSIFBinding">
<java:address className="oracle.bpel.services.workflow.task.impl.TaskServiceWSIF"/>
</port>
</service>
