Web Services

Apache CXF
Apache CXF is an open source (web) services framework. CXF helps you build and develop services using frontend programming APIs, like you build and develop services using frontend programming APIs, like JAX-WS. These services can speak a variety of protocols such as SOAP, XML/HTTP, RESTful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI.

Axis
Axis is the third generation of Apache SOAP (which began at IBM as SOAP4J). It also includes: as SOAP4J). It also includes: * a simple stand-alone server, * a simple stand-alone server, * a server which plugs into servlet engines such as Tomcat, * extensive support for the Web Service Description Language (WSDL), * emitter tooling that generates Java classes from WSDL. * some sample programs, and * a tool for monitoring TCP/IP packets.

UDDI4J
UDDI4J is a Java class library that provides an API to interact with a UDDI (Universal Description, Discovery and Integration) registry. with a UDDI (Universal Description, Discovery and Integration) registry. The UDDI Project is a comprehensive, open industry initiative enabling businesses to (I) discover each other, and (II) define how they interact over the internet and share information in a global registry architecture. UDDI is the building block which will enable businesses to quickly, easily and dynamically find and transact with one another via their preferred applications.

WSIF
The Web Services Invocation Framework (WSIF) is a simple Java API for invoking Web services, no matter how or where the services are for invoking Web services, no matter how or where the services are provided.

Caucho Hessian
Hessian is a lightweight, self-describing binary RPC protocol The Hessian binary web service protocol makes web services usable The Hessian binary web service protocol makes web services usable without requiring a large framework, and without learning yet another alphabet soup of protocols. Because it is a binary protocol, it is well-suited to sending binary data without any need to extend the protocol with attachments.

Crispy
The intention from Crispy is a easy communication with different kind of services. Services are RMI, WebService, REST, XML-RPC, EJB, kind of services. Services are RMI, WebService, REST, XML-RPC, EJB, Burlap, Hessian or other. With Crispy you can invoke all services with the same interface. You must dont know, how the service-technology work. The kind of communication is describe in properties and it can be easy change. The remote calls are simple Java Object call. You can integrate Crispy (for example) in a Service Oriented Architecture (SOA) or in a Rich Client Platform (RCP).

Apache Scout
Apache Scout aims to be an open source implementation of the Java API for XML Registries (JAXR) specification. It has level 0 capability API for XML Registries (JAXR) specification. It has level 0 capability support. It can talk to UDDI registries.

Apache Axis2
Apache Axis2, the third generation Web services engine is more efficient, more modular and more XML-oriented than its predecessor efficient, more modular and more XML-oriented than its predecessor Apache Axis. It is carefully designed to support the easy addition of plug-in modules that extend its functionality for features such as security and increased reliability.

Metro
Metro is a high-performance, extensible, easy-to-use web service stack. It is a one-stop shop for all your web service needs, from the stack. It is a one-stop shop for all your web service needs, from the simplest hello world web service to reliable, secured, and transacted web service.

XFire
XFire is a next-generation java SOAP framework. At its core is a light message processing model used to interact with SOAP messages via light message processing model used to interact with SOAP messages via STAX.

WSIL4J
WSIL4J is a Java class library that provides an API that is can be used to locate and process WS-Inspection documents. This class be used to locate and process WS-Inspection documents. This class library can be used to read and parse a WS-Inspection document, as well as generate a new WS-Inspection document.

SOAP UDDI
SOAP UDDI is UDDI 2.0 compliant registry for Web services. With this UDDI Registry, Web services developers can publish and test their this UDDI Registry, Web services developers can publish and test their applications in a secure, private environment for their own applications.

XINS
XINS is an Web Services technology, supporting SOAP, XML-RPC and REST. It consists mainly of an XML-based specification format and a REST. It consists mainly of an XML-based specification format and a Java-based implementation framework. From the API specifications, XINS can generate HTML, WSDL, client-side code, server-side code and test forms.
