Abstract: A method, system and machine accessible medium for establishing connectivity to a remote computer system by using connectivity objects descriptors provided with services and libraries SDAs. A service or in a library SDA provides a description of how to establish a connectivity object for accessing a remote system. When the SDAs are deployed on an application server, all packed descriptions are stored in a repository. The connectivity is established at server startup in accordance with the descriptions and is accessible for all applications, services and libraries while the server is running.

Abstract: A method, system and machine accessible medium for validating a plurality of connections to a backend in a distributed system. A connection request requiring access to a backend is processed at a first node of a distributed system. The access to the backend enabled through a connection from a plurality of connections on the first node. The plurality of connections on the first node is validated in response to a connection request failure. A plurality of connections on a second node is validated in response to the connection request failure.

Abstract: System and method to bundle deployment descriptors with enterprise archives (“EAR”). An application is bundled with at least one deployment descriptor file within an EAR. The deployment descriptor file defines properties to establish connectivity to network services. Syntax of the deployment descriptor files is verified with reference to rules definition files included within the application server. Connectivity to the network services is established based on the properties defined in the deployment descriptor files, if the syntax of the deployment descriptor files verifies as valid.
