An enterprise component-based software development system includes a component platform with a number of development tools and services that enable rapid and straightforward development of component-based systems. The component platform describes a middle tier architecture for a multi-tier, multi-user application. It defines the services and facilities as well as the structure in which components can execute. It helps to provide an extensible platform for the construction, management and execution of component-based software. A messaging platform facilitates communication between different computers. When a component requests a service from another component, the request is serialized and encoded into a platform-independent language such as XML. The XML-encoded message is transmitted over the Internet using an HTTP protocol to a receiving computer, which validates the message and delivers it to the component providing the requested service. Since XML is a platform and architecture independent language, requests processed in this way can be used by a wide variety of disparate systems.

System and method for component-based software development

A multi-channel and multi-capability facsimile system including N(.gtoreq.2) signal-carrying facsimile channels, an image server means to process, store and retrieve document image information, and a master processing unit to control the process by which information is transferred between a facsimile channel and the image server means, and to enable and disable data compression and expansion document image information that is provided to or received from the facsimile channels. The system: (1) allows visual display of document pages sent and/or received in the resolution in which the document is originally received or generated; (2) allows transmission, receipt and storage of document image information and speech or voice signals; (3) allows control of the destination address and route used for transmitted document and speech infomation, using the DTMF touch tone signaling available with a telephone; (4) supports CCITT group 2, Group 3 and Group 4 standards.

Multi-capability facsimile system

Method and apparatus for providing high resolution images for static display of document pages that are scanned in through a document scanner at high resolution, with reduced bandwidth requirements. In one embodiment, groups of four scanned image pixel values, each one bit in length, are reduced to a single two-bit pixel value that determines a pixel value for a display image pixel; and selected displayed image pixel values are periodically varied between the original displayed image pixel value and an alternative pixel value to restore the perception of high resolution available in the scanned image.
