ServletExec 6.0 supports web services developed using the Java API for XML Web Services (JAX-WS) 2.0 (JSR 224).
JAX-WS replaces Sun's Java Web Services Developer Pack (JWSDP). In other words, JAX-WS replaces JAX-RPC.
Additional details about that can be found
here where it states:
Originally, JAX-WS 2.0 was named JAX-RPC 2.0 and the goal was to be backward compatible with JAX-RPC 1.1. Sometime after JAX-RPC 2.0 EA1 release, JAX-RPC 2.0 specification was renamed to JAX-WS 2.0 and the goal of being backward compatible with JAX-RPC 1.1 was abandoned. JAX-WS 2.0 defines an all new set of packages and removes JAX-RPC 1.1 specific APIs. This means that JAX-WS is a completely different technology than JAX-RPC and thus cannot run JAX-RPC applications. If you have an existing JAX-RPC application it must be converted to work with JAX-WS.JAX-WS 2.0 is distributed inside Glassfish v2 (use b46 or higher).
JAX-WS 2.0 is an integrated toolset that allows developers to build, test
and deploy XML applications, Web Services, and Web applications. It includes or leverages features such as:
- A Fully Dynamic Runtime
- SOAP 1.2
- XML/HTTP Binding
- JAXB 2.0
- Annotations
