Generating WSDL and Schema from a Java Interface

No WSDL? You can use the New Interface wizard as a quick start to generating the basics of a WSDL.

Generating WSDL and Schema from a Java Interface

Once you have set up your Java project in Process Developer's Project Explorer, you can generate WSDL and schema. A BPEL process requires a WSDL interface, and Process Developer automatically generates it from your Java interface.

Additionally, Process Developer automatically synchronizes the generated WSDL with any changes that you might make to the source Java.

To generate WSDL and schema
:

In your Java orchestration project, create a new BPEL process in the bpel folder.

In Participants view, right-mouse click on Partner Service Provider and select New Partner Service Provider
.

In the Partner Service Provider
dialog, select Generate Interface
.

In the New Interface wizard, select From a Java Interface.

Browse to your Java interface and select it.

Notice that the new WSDL is generated in the wsdl folder of your project.

Select Finish
, and then select OK
in the Partner Service Provider
dialog.

WSDL Generation

The following actions occur when you generate a WSDL and schema from a Java interface:

All methods in the Java interface manifest as WSDL operations.

All method arguments manifest as top-level XML schema element declarations. The arguments are generated with generic names, such as "argl_string". To generate actual argument names, see Generating Argument Names for Schema Elements.

The method return type manifests as a top-level XML schema element declaration.

All declared exceptions on the method manifest as WSDL faults.

The WSDL is commented with "Do Not Edit" since it is a derived file that can be automatically updated.

The resulting WSDL contains the following constructs:

One Partner Link Type named [JavaInterfaceName
]

PLT

One Port Type named [JavaInterfaceName
]

One Operation within the port type for each method in the Java Interface

Two messages for each Java interface method:

One message for the method's arguments named [methodName
] with a single part of the same name.

One message for the method's return value named [methodName
]

Response

with a single part of the same name.

Two embedded schema elements for each Java interface method:

One element to model the Java interface method's arguments named methodName
.

One element to model the Java interface method's return value named [methodName
]

Response

A schema complexType and a schema element for each Java class used by the interface.

Schema Generation

Top-level element declarations are created for each of the explicit class references.

The implicit declarations manifest as top-level complexTypes and are reused throughout other parts of the schema (if applicable).
