Diffrence between Top down and Bottom up apprach,
June 9, 2008 at 4:43 AM

There is only the top-down approach (contract first) to build SOA based applications. The WSDL is designed from a business point of view and is not driven by a service consumer or an existing application. The "WSDL to Java" tool generates java code according to JAX-RPC or JAX-WS. These classes can then adapt the existing business logic.


The bottom up approach does generate web services which design is driven from an application point of view (developer driven) and will not address the need for other consumers.
