Application messaging system with flexible message header structure
First Claim
1. A system for passing messages from a first application to a second application in a distributed application server comprising:
- a message modulator at a first entity for modulating a message, each modulated message having a flexible message header and a plurality of typed container modules, wherein the modulating a message includes creating the flexible message header and the plurality of typed container modules;
a message receiver at a second entity for demodulating said typed container modules to regenerate said message; and
wherein said flexible message header operates in an edit mode for editing and modulating a message, and in a storage mode for storing a message, wherein in said edit mode, each typed container module, except those containing user data, is prefixed with an attachment unit which comprises pointers to point to the next typed container module and the previous typed container module, and wherein in said storage mode the attachment unit is removed from the typed container modules.

Abstract
The Flexible Message Header (FMH) is a typed modular message structure comprising one or more Typed Container Modules (TCM)—stateful message modules with a compact header (Typed Container Header, TCH), a user definable payload (Typed Container Body, TCB), and a set of payload-specific callback to handle the lifecycle of the module at the different state such as creation, preparation, manipulation, resizing, transferring, and deletion. A single message comprises a small header with various numbers of TCMs. The integrity of the entire message is not affected by dynamically modifying, adding or removing TCM from the message. Major message content change can be achieved by either adding a TCM or swapping the TCM with different TCM. Minor message content change can be achieved by either modifying or expanding the TCM directly within the message. New features can be supported by adding new TCM and new code to process the new TCM.

9. A method of messaging between applications in a distributed application system, comprising the steps of:
-
modulating a message, each modulated message having a flexible message header and a plurality of typed container modules, wherein the modulating a message includes creating the flexible message header and the plurality of typed container modules; demodulating said typed container modules to create a message; and wherein said flexible message header operates in an edit mode for editing and modulating a message, and in a storage mode for storing a message, wherein in said edit mode, each typed container module, except those containing user data, is prefixed with an attachment unit which comprises pointers to point to the next typed container module and the previous typed container module, and wherein in said storage mode the attachment unit is removed from the typed container modules. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
