Web Services Interoperability Technology

WSIT is a technology built on top of JAX-WS and JAXB aiming at delivering interoperability with MS Windows Communication Foundation in the following areas:

• Messaging
  
  
  
  • SOAP: Support for the SOAP wire protocol is built into JAX-WS.
  
  
  • MTOM: JAX-WS also includes support for Message Transmission Optimization Mechanism (MTOM) for optimizing the wire format of SOAP messages.
  
  
  
  • WS-Addressing: supports normalized web service addresses, enabling multiple transports to be used (besides HTTP).
  
  
  
  


• Metadata
  
  
  
  • WSDL: Support for the Web Services Description Language is built into JAX-WS
  
  
  • WS-Policy: Policies express and handle requirements and capabilities of web service consumers and providers
  
  
  
  • WS-MetadataExchange: "WS-MEX" is a protocol to enable a consumer to obtain a service's metadata (i.e., its WSDL and policies). Think of it as a bootstrap mechanism for communication.
  
  
  
  


• Security
  
  
  
  • WS-SecurityPolicy: Defines specific policies (i.e., assertions) that describe how messages are secured.
  
  
  • WS-Security: Provides message content integrity and confidentiality (even in the presence of intermediaries).
  
  
  • WS-Trust: Provides methods for issuing, renewing, and validating security tokens used by WS-Security. It also provides ways to establish and broker trust relationships.
  
  
  
  • WS-SecureConversation: Can be viewed as a security optimization (i.e., better message level security and efficiency in multiple-message exchanges).
  
  
  
  


• Quality of Service (QoS)
  
  
  
  • WS-ReliableMessaging: Enables a messaging system to recover from failures caused by messages that are lost or misordered in transit.
  
  
  • WS-Coord: A framework for providing protocols that coordinate the actions of distributed applications. Used by WS-AtomicTransactions.
  
  
  • WS-AtomicTransactions: Supports two phase commit semantics such that either all operations invoked within an atomic transaction succeed or are all rolled back.
