A system and a method for dynamic or as-needed activation of EJB's in response to a client request. Particularly, EJB object activation allows the system to clean up currently unused objects, and to recreate them on demand when a client needs them. EJB activation thus provides support for remote server objects that require persistent access overtime and that can be activated by the system. In accordance with one embodiment the object activation system activates a remote server EJB for a client based on an ActivationID previously received from the server. This relieves the container from keeping track of remote object interfaces, and allows the system to be more scalable.

A system and method for migrating services in a Java server environment, and particularly to a mechanism for migrating message driven beans. In accordance with the present invention, the JMS server and MDB's are designed to be migratable from one application server to another. In order to expedite Message Driven Bean (MDB) recovery in a cluster environment before a failed server restarts, the MDB is implemented as a migratable service. This enables the migratable service framework to migrate the MDB and JMS server to another available server in the same cluster. After migration, MDB obtains ownership of the JMS server, and continues to pull the messages from the JMS server on behalf of the failed server. This allows the backup server to read the message from JMS server and continue the service.

A system and method of indirectly modifying an environmental condition at a test site in one embodiment includes providing a test site on a substrate, providing a first activatable stimulant at the test site, providing an actuator configured to activate the first activatable stimulant at the test site, controlling the actuator to activate the first activatable stimulant, and modifying the local chemical environment at the test site with the first activated stimulant.

A system and method for increasing entity bean performance in an application server environment. The system reduces the need for multiple or unnecessary queries by formulating a join query for the related beans and applying this query to the database. When a request is made to a database to read or retrieve a set of EJB beans, related beans are simultaneously retrieved and stored in a cache. In this manner, when the client sends a request for any of these related beans, they can be supplied from the cache rather than making another call to the database.

A method and system are provided for storing multiple instances of a CMP bean enrolled in a transaction by utilizing CMP batch operations to update multiple entries in a database table in one SQL statement only, thus avoiding multiple database roundtrips. The batch operation of CMP beans can be enabled by specifying certain options in a DTD file. As part of the batch operation feature, another option may be added to the DTD file as well, enabling the container to delay all database operations in a transaction until the commit time, automatically sort the database dependency between the operations, and send these operations to the database in a way to avoid any potential database constraint violations.
