When a Web service application is deployed into WebSphere Application
Server, an instance is created for each application or module. The instance
contains deployment information for the Web module or enterprise JavaBean
(EJB) module, including client bindings.
Before you begin
Deploy the Web service into
WebSphere Application Server.
To complete this task, you need to know
the topology of the URL endpoint address of the Web services servers and which
Web service the client depends upon. You can view the deployment descriptors
in the administrative console to find topology information. See the article View Web services server deployment descriptors for
more information.
About this task
The client bindings define the Web Services Description Language
(WSDL) file name and preferred ports. The relative path of a Web service in
a module is specified within a compatible WSDL file that contains the actual
URL to be used for requests. The address is only needed if the original WSDL
file did not contain a URL, or when a different address is needed. For a service
endpoint with multiple ports, you need to define an alternative WSDL file
name.
The following steps describe how to edit bindings for a Web service
after these bindings are deployed on a server. When one Web service communicates
with another Web service, you must configure the client bindings to access
the downstream Web service.
You can also configure client bindings
with wsadmin.
To configure client bindings through the
administrative console:
Procedure
- Open the administrative console.
- To view this administrative console page,
click Applications >Enterprise Applications > application_instance > Web
modules or EJB modules > module_instance >Web services
implementation scope.
- Find the Web service you want to update.
The Web
services are listed in the Web Service field.
- Select the WSDL file name from the drop down box in the WSDL file
name field.
- Click Edit in the Preferred port mappings field to configure
the default port to use.
- Specify the port type and the preferred ports in the Port type
and Preferred ports fields.
Configuring the preferred port enables
you to select an optimal port implementation use non-SOAP protocols. See RMI-IIOP Web services using JAX-RPC for
more information about using non-SOAP protocols.
- Click Apply and OK.
- Click Edit in the Port information field to configure the
request timeout, the overridden endpoint, and the overridden binding namespace
for a port.
Configuring the request timeout accommodates complex
topologies that can have multiple cascaded Web services that involve multiple
hops or long-running services.
Timeout values can be configured based
on observed behavior of the overall system as integration proceeds. For example,
a Web service client might time out because of changing network conditions
or the performance of an external Web service. When you have applications
containing Web services clients that timeout, you can change the request time
out values for the clients.
- Click Apply and OK.
Results
Your Web service client bindings are configured.
What to do next
Now you can finish any other configurations, start or restart the
application, and verify the expected behavior of the Web service.
