WAS v8.5 > Develop applicationsDevelop web services - Transaction support (WS-Transaction)
WS-Transaction is an interoperability standard that includes the WS-AtomicTransaction, WS-BusinessActivity, and WS-Coordination specifications. The Web Services Atomic Transaction (WS-AT) support in the application server provides transactional quality of service to the web services environment. Distributed web services applications, and the resources they use, can take part in distributed global transactions. With Web Services Business Activity (WS-BA) support in the application server, web services on different systems can coordinate activities that are more loosely coupled than atomic transactions. Such activities can be difficult or impossible to roll back atomically, and therefore require a compensation process if an error occurs. Web Services Coordination (WS-COOR) specifies a CoordinationContext and a Registration service with which participant web services can enlist to take part in the protocols that are offered by specific coordination types.
Subtopics
- Create an application that uses the Web Services Business Activity support
To create an application component that uses the business activity support, set Run EJB methods under a Business Activity scope in the deployment descriptor of the relevant application component, and if required, create and specify a compensation handler for the application to use if there is an error. You then build the component into the application and deploy the application onto a server that has the business activity support enabled. The application component can be either an enterprise bean or a web service that is implemented as an enterprise bean.
