Patent ID: 7734677

Claim:
Method for dynamically integrating Backend System instances into a Java2 Enterprise Edition (J2EE) application server environment, comprising: operating server hardware of a cluster of nodes to execute a plurality of J2EE applications, provide one or more Backend System instances through the cluster of nodes, and establish processing communication between a J2EE application server and said Backend System instances by deploying a Java2 Connector (J2C) connector suitable for Backend System instances belonging to the same type of Backend Systems into said J2EE application server environment by using a J2C deployment descriptor; restarting said J2EE application server; using a Join/Leave manager to: detect availability of Backend System instances; determine access data for particular ones of said Backend System instances, wherein said access data are detected by an automation detection method which scans the accessible systems in the distributed application environment for Backend System instances, said access data containing information sufficient to identify and connect to the particular Backend System instances; persistently storing said access data to a storage medium; and reading said access data and passing them as a part of a request to said J2C connector, such that processing communication can be established automatically between said cluster of nodes executing said J2EE applications and those providing Backend System instances dynamically during runtime without requiring said J2EE applications to be reinitiated and without requiring said J2EE application server environment to be restarted.
