Application visibility

The visibility or isolation between the client and Web modules depends on the class loader policy defined in the server-side configuration. This policy affects the packaging of applications and the runtime behavior of packaged applications deployed on application servers.

WebSphere(R) Application Server Version 5.1.1 uses class loader policies instead of the module visibility modes. There are two levels of class loader policy:

All Branch Transformation Toolkit sample applications use the MULTIPLE/MODULE combination. It is the default combination for Version 5.1 of WebSphere Studio Application Developer and WebSphere Application Server 5.1.1 and it matches the J2EE 1.3 specification. This combination isolates all applications from each other on the server side and each Web module uses its own class loader.
