Abstract

Examples of methods, apparatus, and computer program products are disclosed for facilitating access to one or more services in a network environment. At a host, a request is received from a client machine in communication with the host over a network. An asynchronous service description file indicates one or more asynchronous communication techniques configured to be performed to access or communicate with a service over the network. The asynchronous service description file is a conversion of a synchronous service description file indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service. The asynchronous service description file is provided to the client machine.

Claims

1. A system comprising:

one or more processors operable to cause;

processing a request from a client machine in communication with a host over a network;

obtaining first data indicating one or more asynchronous communication techniques configured to be performed by a machine to access or communicate with a service over the network, the first data being a conversion of second data indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service; and

providing, to the client machine, the first data.

2. The system of claim 1, wherein the first data and the second data are service description files in web service description language (WSDL) format.

3. The system of claim 1, the one or more processors further operable to cause:

obtaining permission information indicating a permission of the client machine to access one or more services.

4. The system of claim 3, wherein obtaining the permission information includes:

performing one or more security management operations in association with the client machine or with a user of the client machine.

5. The system of claim 4, wherein the security management operations include one or more of:

authentication, authorization, security policy enforcement, decryption, and validation of a digital signature.

6. The system of claim 3, wherein obtaining the permission information includes:

retrieving the permission information from a policy repository.

7. The system of claim 1, the one or more processors further operable to cause:

providing, at the host, one or more interfaces for communications between the client machine and the synchronous service over the network, the one or more interfaces permitting;

synchronous communications with the synchronous service in accordance with the second data, and asynchronous communications with the client machine in accordance with the first data.

8. The system of claim 1, the one or more processors further operable to cause:

processing a message from the client machine at an asynchronous interface;

processing the message at the host; and

providing the processed message to the synchronous service at a synchronous interface.

9. The system of claim 8, wherein providing the processed message to the synchronous service includes:

sending the processed message in response to polling by the synchronous service.

10. The system of claim 1, the one or more processors further operable to cause:

processing a message from the synchronous service at a synchronous interface;

processing the message at the host; and

providing the processed message to the client machine at an asynchronous interface.

11. The system of claim 1, wherein obtaining the first data includes:

converting the second data to the first data.

12. The system of claim 1, wherein obtaining the first data includes:

retrieving the first data from a storage medium accessible at the host.

13. A method comprising:

receiving, at a host, a request from a client machine in communication with the host over a network;

obtaining, at the host, first data indicating one or more asynchronous communication techniques configured to be performed by a machine to access or communicate with a service over the network, the first data being a conversion of second data indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service; and

providing, to the client machine, the first data.

14. The method of claim 13, wherein the first data and the second data are service description files in web service description language (WSDL) format.

15. The method of claim 13, the method further comprising:

obtaining permission information indicating a permission of the client machine to access one or more services.

16. The method of claim 15, wherein obtaining the permission information includes:

performing one or more security management operations in association with the client machine or with a user of the client machine.

17. A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions configured to cause:

processing a request from a client machine in communication with a host over a network;

obtaining first data indicating one or more asynchronous communication techniques configured to be performed by a machine to access or communicate with a service over the network, the first data being a conversion of second data indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service; and

providing, to the client machine, the first data.

18. The computer program product of claim 17, wherein the first data and the second data are service description files in web service description language (WSDL) format.

19. The computer program product of claim 17, the program code including further instructions configured to cause:

obtaining permission information indicating a permission of the client machine to access one or more services.

20. The computer program product of claim 19, wherein obtaining the permission information includes:

performing one or more security management operations in association with the client machine or with a user of the client machine.
