A system and method for integrating business logic implemented in Enterprise JavaBeans (EJBs) into a user interface framework are disclosed. A design-time environment includes an analyzer that analyzes selected EJBs and generates a model representation of the selected EJBs, and further includes a metadata provider to provide additional metadata to the model representation. A runtime environment has a generic model component to access the selected EJBs based on their model representation, and executes the selected EJBs in the user interface framework.

A runtime environment injects an instance of an external resource into an application component to be executed in the runtime environment by first determining an external resource associated with the application component, then selecting from a library of injectors an injector to inject an instance of the application component with an instance of an external resource referenced by the external resource annotation. The selected injector determines the instance of the application component to inject with the instance of the external resource and injects the instance of the application component with the instance of the external resource.

A system and method are described for reducing messaging data traffic within a cluster of servers. According to one embodiment, each server within the cluster initially attempts to register as a message listener for a particular messaging destination (e.g., JMS Topic). After one server successfully registers, a locking service locks out all other servers from registering as listeners. Subsequently, any messages directed to the messaging destination are forwarded only to the registered server and not the other servers in the cluster, thereby reducing messaging data traffic. If the registered server becomes inoperative, the cluster is notified and the other servers again attempt to register. The first to successfully register is again identified as the listener for the cluster.

A method is described in which a computing system creates an object containing information that describes a reference. The reference is used to implement a communication session. The computing system serializes the object into a byte stream. The computing system causes the byte stream to be stored outside the computing system so that the communication session can be restored on another computing system should the computing system fail.
