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.

Dependent claims

A method for enumerating data pages in a stateless, distributed computing environment, comprising:

(a) calling a stateless application by a user interface, wherein sad stateless application is an Enterprise JavaBeans (EJB) compliant session bean;
(b) invoking a stateful data structure by the stateless application, wherein said stateful data structure is an EJB compliant session bean;
(c) retrieving from a datastore by the stateful data structure a plurality of handles corresponding to a plurality of data;
(d) selectively retrieving data by the stateful data structure from the datastore via the handles, said data corresponding to a display pare requested by the user,
(e) converting the stateful data residing within the stateful data structure to stateless data;
(f) passing the stateless data to JAVA servlet;
(g) constructing by the JAVA servlet the display page comprising the stateless data;
and
(h) returning the display page/to the user interface.
