Abstract

A large message can be stored by separating the message into an envelope portion containing information such as headers, protocols, and addresses, and a payload portion containing items such as file attachments. The envelope portion can be stored in local storage, while the payload can be stored to a persistent store. The message can be processed incrementally, such that the entire message is never in system memory. Once the envelope portion is processed, the payload portion can be read in increments without being processed, and those increments written directly to the persistent store. Alternatively, the payload can be streamed to the persistent store. A pointer in the envelope can then be used to locate and retrieve attachments from persistent storage. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Claims

1. A system for providing access to a message in a computer environment, comprising:

a computer memory;

a persistent store; and

an integration component that receives the message, and then

creates an envelope and payload for the message,

stores the payload in the persistent store,

creates within the envelope a header information and pointers to portions of the payload,

stores the envelope in the memory, and

provides access to applications to access the envelope and retrieve selected portions of the message from the persistent store using the pointers in the envelope.

2. The system of claim 1, wherein the step of creating a separate envelope and payload includes parsing the message with a protocol parser to identify portions of the message to the integration component.

3. The system of claim 1, wherein the step of creating a separate envelope and payload includes parsing the message with an XML parser to read header and body portions of the message, and to separate the head and body portions into the envelope and payload respectively.

4. The system of claim 1, wherein the step of creating a separate envelope and payload includes processing the message in increments.

5. The system of claim 1 wherein the persistent store is located at the computer that receives the message.

6. The system of claim 1 wherein the persistent store is located at a computer different from the one that receives the message, and wherein the persistent store is shared among a plurality of computers for storage of and access to message payloads for the plurality of computers.

7. A method for providing access to a message in a computer environment, comprising the steps of:

receiving the message at an integration component at a computer;

creating a separate envelope and payload for the message;

storing the payload in a persistent store;

creating within the envelope a header information and pointers to portions of the payload;

storing the envelope in the computer'"'"'s memory; and

providing access to applications to access the envelope and retrieve selected portions of the message from the persistent store using the pointers in the envelope.

8. The method of claim 7, wherein the step of creating a separate envelope and payload includes parsing the message with a protocol parser to identify portions of the message to the integration component.

9. The method of claim 7, wherein the step of creating a separate envelope and payload includes parsing the message with an XML parser to read header and body portions of the message, and to separate the head and body portions into the envelope and payload respectively.

10. The method of claim 7, wherein the step of creating a separate envelope and payload includes processing the message in increments.

11. The method of claim 7 wherein the persistent store is located at the computer that receives the message.

12. The method of claim 7 wherein the persistent store is located at a computer different from the one that receives the message, and wherein the persistent store is shared among a plurality of computers for storage of and access to message payloads for the plurality of computers.

13. A computer readable medium including instructions stored thereon which when executed cause the computer to perform the steps of:

receiving the message at an integration component at a computer;

creating a separate envelope and payload for the message;

storing the payload in a persistent store;

creating within the envelope a header information and pointers to portions of the payload;

storing the envelope in the computer'"'"'s memory; and

providing access to applications to access the envelope and retrieve selected portions of the message from the persistent store using the pointers in the envelope.

14. The computer readable medium of claim 13, wherein the step of creating a separate envelope and payload includes parsing the message with a protocol parser to identify portions of the message to the integration component.

15. The computer readable medium of claim 13, wherein the step of creating a separate envelope and payload includes parsing the message with an XML parser to read header and body portions of the message, and to separate the head and body portions into the envelope and payload respectively.

16. The computer readable medium of claim 13, wherein the step of creating a separate envelope and payload includes processing the message in increments.

17. The computer readable medium of claim 13 wherein the persistent store is located at the computer that receives the message.

18. The computer readable medium of claim 13 wherein the persistent store is located at a computer different from the one that receives the message, and wherein the persistent store is shared among a plurality of computers for storage of and access to message payloads for the plurality of computers.
