A computer implemented method, apparatus, and computer usable program product for managing session data. The process determines whether preexisting session data associated with a request for content is present in response to receiving the request. Responsive to an absence of the preexisting session data being associated with the request, the process generates session data associated with the request. The process then generates a response page having a set of forms including a set of hidden fields. The set of hidden fields include the session data. Thereafter, the process sends the response page to a client browser.

Implementing browser based hypertext transfer protocol session storage

The present invention is a multi-protocol object distribution system. The multi-protocol object distribution system can include one or more remote procedure call (RPC) transport protocol stubs; and, a meta-stub configured to select individual ones of the RPC transport protocol stubs through which distributed object services can be provided to requesting clients in the object distribution system. The RPC transport protocol stubs can include both a default RPC transport stub, and at least one other RPC transport stub which the meta-stub can select based upon changing conditions in the object distribution system. Importantly, the meta-stub can automatically select the default RPC transport stub by default.

Multi-protocol object distribution

A method, a system, an apparatus, and a computer program product are presented for object-oriented management of serializable objects. An object has a set of attributes and a class version number, which identifies the object as an instance of a specific version of a class. In addition, each attribute in the object has an attribute version number, which may represent a version of a class in which the associated attribute was initially declared within the class. The object may be serialized into a data stream, and the data stream has the class version number of the object, an attribute value for each attribute in the set of attributes, and an attribute version number for each attribute in the set of attributes. The data stream may also have a class identifier for the class of the object and an attribute count for the set of attributes into the data stream.

Method and system for maintaining forward and backward compatibility in flattened object streams

A method, system, and computer program product are described for storing attribute data in an object oriented environment. A base class and a subclass are defined within an object. The object is defined within the object oriented environment. An attribute is defined within the subclass. The attribute data defined for the subclass is stored within the base class. The attribute data is not stored within the subclass.

Method, system, and product for storage of attribute data in an object oriented environment

A method and apparatus in a data processing system for managing transactions. A request event is received at a transporter object. The request event includes a target and an indication of how to handle the request event. A destination object is identified within the plurality of destination objects using the request event to form an identified destination object. The request event is sent to the identified destination object, wherein the identified destination object handles the request using the indication and accesses the target.

Method and apparatus in a data processing system for the issuance and delivery of lightweight requests to concurrent and multiple service providers

A method and apparatus of an architectural pattern for creating applications for a data processing system. A graphical user interface is created in which the graphical user interface includes a plurality of components. Processes for presenting the plurality of components and receiving user input are handled by a first set of graphical objects, wherein in response to selected user input, a first event is generated. An application object is created in which the application process controls an order in which the graphical objects present the set of components and process the event and wherein the application generates a second event. A transport object is created in which the transport object processes the second event and forwards the second event for processing to a destination within the plurality of destinations. A plurality of destination objects are created in which each destination object within the plurality of destinations objects handles accessing a destination within the plurality of destinations.

Controlling presentation of a GUI, using view controllers created by an application mediator, by identifying a destination to access a target to retrieve data

A method and apparatus in a data processing system for managing permissions in an application. A user input is received at a container handled by a view controller, wherein the user input requests a change in permissions in the application. This user input, may be, for example, a change in security in an application through a login process. A view event describing the user input is generated. The view event is received at an application mediator. Responsive to receiving the view event, by the application mediator, a request event is generated and a permission corresponding to the user input is received. The permission alters an item, which may be in either of both the view controller and the application mediator.

Method and apparatus in a data processing system for the separation of role-based permissions specification from its corresponding implementation of its semantic behavior

A method and apparatus in a data processing system for refreshing data in an application. A call is received to update data in the application, wherein the data is destined for a component in the application. A data type is identified for the data. Responsive to the data type being a handled data type, the data is formatted and a refresh is called on the component.

Mechanism for cross channel multi-server multi-protocol multi-data model thin clients

A method and apparatus in a data processing system for displaying a graphical user interface. A container is displayed in a graphical user interface from a set of containers, wherein a display of the container handled by a view controller from a set of view controllers. Each view controller handles the display of an associated container within the set of containers and user input for the associated container. A display of the set of containers is altered by an application mediator, wherein the set of containers are displayed in an order determined by the application mediator.

Method and apparatus in a data processing system for the controlling and sequencing of graphical user interface components and mediating access to system services for those components

A method and apparatus for a data processing system for accessing classes and methods in an object oriented system. Responsive to receiving a selected user input to a container, a view event is sent from a view controller to an application mediator. The view event identifies an action taken to generate the selected user input. A request is selectively generated based on the view event, wherein the request event includes a major code identifying a class name as a destination and a minor code identifying a method name a function to be invoked. The request event is sent to a transporter. The transporter acts as a router to send the request event to an appropriate destination object from a plurality of destination objects. Responsive to receiving the request event at the transporter, the request event is sent to a destination object within a plurality of destination objects based in the class name. The destination object formats the request event into a form recognizable by the destination associated with the destination object. The destination may be located on a remote data processing system. The request event is used to access the class or method identified in the request event. The access may be, for example, an invocation of the method.

Sending a view event, and a request event having a class name and a method name

A method and apparatus in a data processing system for serialization data. A serializer receives a data element for serialization, wherein the data element includes a class name string. Responsive to receiving the data element, the serializer replaces the class name string with a code having a smaller size than the class name string to form a modified data element. Responsive to forming the modified data element, in which the serializer serializes the modified data element. The serialized data is transmitted and deserialized by deserializer which replaces the indicator with the class name.
