Task overview: Implementing shared work areas

About this task

The work area service enables application developers to implicitly propagate information beyond the information passed in remote calls. Applications can create a work area, insert information into it, and make remote invocations. The work area is propagated with each remote method invocation, eliminating the need to explicitly include an appropriate argument in the definition of each method. The methods on the server side can use or ignore the information in the work area as appropriate.

Before proceeding with the steps to implement work areas, as described below, review the topic Work area service: Overview.

Procedure

  1. Developing applications that use work areas. Applications interact with the work area service by implementing the UserWorkArea interface.
  2. Managing work areas. The work area service is managed using the administrative console.
  3. Configuring work area partitions You can create multiple work areas with additional configuration options than the UserWorkArea partition.
  4. Propagating work area context over Web services You can propagate work area context on a Web service call instead of an RMI/IIOP call.
