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 bean module, including implementation scope, client bindings and deployment descriptor information. There are three levels of scope that can be set: application, session and request.
Before you begin
Deploy the Web service into WebSphere Application Server.Why and when to perform this task
Web Services for Java 2 platform Enterprise Edition (J2EE) specifies that Web services implementations must be stateless. Therefore, to maintain specification compliance, the scope can remain at the application level because the state relevant to the individual sessions level or the requests level is not supposed to be maintained in the implementation. If you want to deviate from the specification and want to access a different JavaBean instance, because you are looking for information that is located in another JavaBean implementation, the scope settings need to change.
The setting that you configure for the scope determines how frequently a new instance of a service implementation class is created for the Web service ports in a module. Use this task to configure the scope of a Web service port.You can also configure the scope with the wsadmin tool.
To change the scope setting through the administrative console:
Steps for this task
Result
The scope for a Web service port is configured.What to do next
Now you can finish any other configurations, start or stop the application, and verify the expected behavior of the Web service.Related tasks
