Abstract

A method is described that involves processing a Web services message within an object oriented runtime environment. The processing itself involves executing a plurality of protocols to support a Web service that the message pertains to. Each one of the protocols perform one or more operations that contribute to a different part of the processing. The executing is hibernated by storing state information of the protocols externally from the protocols. The executing is resumed by loading the saved state information back into the protocols. The executing includes one of the protocols performing the following: receiving from an object information retrieved from the message'"'"'s header; and, providing at least a portion of the information to another protocol amongst the plurality of protocols.

Claims

1. A method comprising:

executing an instance of a first protocol of a protocol stack to permit a second protocol of said protocol stack to access a portion of header information of a Web services message during a processing of said Web services message, said executing of said instance of said first protocol of said protocol stack including storing state information of said instance of said first protocol into context information of said Web services message;

placing the processing of said Web services message into hibernation, said placing of said processing of said Web services message into hibernation including suspending said processing of said Web services message and persisting a configuration context associated with said processing of said Web services message, said persisting of said configuration context including keeping said configuration context separate from said processing of said Web services message; and

re-executing said instance of said first protocol to permit said instance of said second protocol to access a portion of header information of an additional Web services message during a processing of said additional Web services message, said permitting of said instance of said second protocol to access said portion of said header information of said additional Web services message including providing a standard interface that enables said instance of said second protocol to access said portion of said header information of said additional Web services message independently of a structure of said header information of said additional Web services message, wherein said re-executing is performed by a machine.

2. The method of claim 1, further comprising executing an instance of a security protocol before said executing of said instance of said first protocol, said instance of said security protocol configured to decrypt an object-oriented representation of said Web services message.

3. The method of claim 1, wherein said instance of said first protocol is further configured to permit an endpoint method that is configured to generate a response to said Web services message to access said portion of said header information of said Web service message through a standard interface such that said endpoint method is immune to changes to a structure of said header information.

4. A non-transitory computer readable storage medium containing program code that, when processed by one or more processors, causes operations to be performed, the operations comprising:

executing an instance of a first protocol of a protocol stack to permit a second protocol of said protocol stack to access a portion of header information of a Web services message during a processing of said Web services message, said executing of said instance of said first protocol of said protocol stack including storing state information of said instance of said first protocol into context information of said Web services message;

placing the processing of said Web services message into hibernation, said placing of said processing of said Web services message into hibernation including suspending said processing of said Web services message and persisting a configuration context associated with said processing of said Web services message, said persisting of said configuration context including keeping said configuration context separate from said processing of said Web services message; and

re-executing said instance of said first protocol to permit said instance of said second protocol to access a portion of header information of an additional Web services message during a processing of said additional Web services message, said permitting of said instance of said second protocol to access said portion of said header information of said additional Web services message including providing a standard interface that enables said instance of said second protocol to access said portion of said header information of said additional Web services message independently of a structure of said header information of said additional Web services message.

5. The non-transitory computer readable storage medium of claim 4, wherein said first protocol stores elements of said header information in a message object of said Web services message.

6. The non-transitory computer readable storage medium of claim 4, further comprising executing an instance of a security protocol before said executing of said instance of said first protocol, said instance of said security protocol configured to decrypt an object-oriented representation of said Web services message.

7. The non-transitory computer readable storage medium of claim 4, wherein said instance of said first protocol is further configured to permit an endpoint method that is configured to generate a response to said Web services message accesses said header information of said Web service message through a standard interface such that said endpoint method is immune to changes to a structure of said header information.

8. A method comprising:

executing an instance of a headers protocol to permit an instance of an additional protocol to comprehend a portion of header information of a first Web services message during a processing of the first Web services message, the executing of the instance of the headers protocol including storing state information of the instance of the headers protocol into context information of the Web services message;

placing the processing of the first Web services message into hibernation, the placing of the processing of the first Web services message into hibernation including suspending the processing of the first Web services message and persisting a configuration context associated with the processing of the Web services message, the persisting of the configuration context including keeping the configuration context separate from the processing of the Web services message; and

re-executing the instance of the headers protocol to permit the instance of the additional protocol to comprehend a portion of header information of a second Web services message during a processing of the second Web services message, the permitting of the instance of the additional protocol to access the portion of the header information of the additional Web services message including providing a standard interface that enables the instance of the additional protocol to access the portion of the header information of the additional Web services message independently of a structure of the header information of the additional Web services message, wherein the re-executing is performed by a machine.

9. The method of claim 8, wherein the permitting of the instance of the additional protocol to comprehend the portion of the header information of the first Web services message includes enabling the instance of the additional protocol to request the portion of the header information of the first Web services message after the executing of the instance of the header protocol.

10. The method of claim 8, wherein the placing of the processing of the first Web services message into hibernation is based on a determination by the instance of the additional protocol that the processing of the first Web services message and the processing of the second Web services is out of order.

11. The method of claim 8, wherein the additional protocol is the Web Services Reliable Messaging (WS-RM) protocol.
