ABSTRACT:
The present invention discloses a method for enumerating data pages in a stateless, distributed computing environment. A user operating a uses interface calls a stateless application, which in turn invokes a stateful data structure to retrieve data from a datastore. Stateful data residing within the stateful data structure is converted to stateless data, and a display page comprising stateless data is returned to the user. Preferably, the stateless application and the stateful data structures are Enterprise JavaBeans (EJB) compliant session beans. In a preferred embodiment, a servlet generates the display page by retrieving the stateless data from the stateful session bean, the display page is returned to the user interface via a communication framework, and data is retrieved from the datastore via a persistence framework.
