In a workload managed system comprising a plurality of server processes each capable of supporting a given program entity, such as an Enterprise JavaBeans&#x2122; specified stateful session bean, a stateful session bean instance is passivated, by writing it to a bean store, on completion of a unit of work. On next use the session bean is reactivated, by reading it from the bean store, in any one of the plurality of servers thereby allowing workload management for stateful session beans. A routing table is maintained, in non-volatile mass storage, that contains location information for units of work and stateful session bean instances, used to maintain unit of work-server affinity for the lifetime of the unit of work Stateful session beans instances are associated with ID keys that include a flag that is used to indicate whether or not the routing table contains location information for the bean instance.

An image data display system in which more than one portion of an image displayed on a screen may be transformed by extraction, scaling or rotation in relation to other areas of the screen concurrently. The image display system is of the type which is capable of receiving transformation operation orders from a control processor prior to being sent the image. As the image is received, the display system performs the transform operations prior to displaying the image data. The control processor is modified to include means to determine when two or more concurrent transforms of portions of an image will cause the portions to be displayed on common areas of the display screen (or overlap) and, means to order and transmit to the display device the list of transforms to be performed so that the image pel definition signals are transmitted to the display device where image portions occupy common areas of the display screen the pel definition signals relating to higher priority portion of the image control the final content of the common areas of the displayed image.
