WebSphere Application Server V7.0.
For SOAP, some performance improvements can be achieved with the MTOM
standard through the optimization of the messages it provides. Avoiding the use

Table 11-1 Planning checklist for Web services
Planning item
Determine if and how Web services will be used.
Determine how Web service clients will call providers (directly, through the service
integration bus, or through an ESB).
Determine if a Web services gateway will be required.
Determine if a UDDI service will be used. If so, decide whether you will subscribe to a
public UDDI service or set up a private UDDI.
Design a security strategy for Web services:
► WS-Security for applications
► Transport-level security
► HTTP basic authentication
Determine if you will use Web service dynamic caching.
Note: JAX-RPC is included in the Java EE 5 specification. If you are new to
Web services, JAX-WS should be the preferred programming model of choice.
