US Patent 7389513 Pooling stateful session enterprise Java beans for reuse

A method of interfacing with a remote engine can include the step of instantiating at least one stateful bean, such as a stateful session Enterprise Java Bean. For each stateful bean instance, an engine can be allocated. Each stateful bean instance can be associated with an allocated engine, where each stateful bean instance can operate as an interface for accessing the associated engine. Each associated stateful bean can then be added to a bean pool so that bean instances in the bean pool are available for handling requests.
