Explanation
JAX-RPC provides three invocation models for calling web services: static stubs generated from WSDL by tools, the Dynamic Invocation Interface (DII) for runtime calls without compile-time stubs, and dynamic proxies that combine type safety with runtime flexibility. These models give developers different trade-offs between convenience and flexibility when invoking services.
