Server side

On the application presentation server side, any request from the client is sent to the screen flow processor request handler.

If the client is an HTML client, its request is sent to the screen flow processor request handler, from where the request can be passed to the Business Process Component on the application logic server for transaction through the WSIF Action, or it can be passed to the bean invokers In the application presentation server and then invokes the Business Process Component or single action EJB on the application logic server for transaction through the EJB Action. The application logic server then processes the transaction.

If the client is a Java(TM) client, its request is sent to the toolkit, and the toolkit then calls the bean invokers. The corresponding invoker In the application presentation server then invokes the Business Process Component or Single Action EJB on the application logic server for transaction through EJB Action. The application logic server then processes the transaction.
