Web service stack: JAX-WS RI and WSIT; WS-Security, WS-ReliableMessaging, WS-AtomicTransactions; part of GlassFish ecosystem.

Lightweight binary RPC protocol; no large framework; good for binary data; Java, Flash, Python, etc. ; Spring integrable.

Apache SOAP stack: stand-alone or servlet engine; WSDL support; Java-from-WSDL tooling; superseded by Axis2.

Integration of Java classes and Avalon services with Axis; deploy SOAP services without WSDD; register class or service for RPC SOAP.

Java servlets to build RESTful web services exposing JDBC data; middle-tier, syndication, or database reporting.

UDDI 2. 0 compliant registry for web services; publish and test in a private, secure environment.

Java library to interact with UDDI registries; publish and discover web services; API for UDDI messages.

JAXR implementation; UDDI 2. 0/3. 0; level 0 capability; talk to UDDI/ebXML registries.

Web Services Invocation Framework: Java API to invoke services from WSDL; protocol- and location-independent.

Lightweight XML RPC protocol from Caucho; simple web services without large frameworks; documented with Hessian (binary sibling).
