Abstract

A system and method that provides remoting services in a distributed object system is provided. The system includes a remote object monitor and a remote object manipulator. The remote object monitor can provide a human readable reference to a remote object, where the human readable reference is a URL (Uniform Resource Locator) and can include protocol information, protocol data, an application name and an object URI (Uniform Resource Identifier). The remote object monitor can also provide metadata concerning a remote object, where the metadata can include information concerning interfaces implemented by a remote object, the type of a remote object, the class hierarchy of a remote object, methods implemented by a remote object, properties implemented by a remote object and attributes implemented by a remote object. The remote object monitor can also provide entry points and code interception for custom attribute based activation processing that can be performed before, after and/or substantially in parallel with non-attribute code associated with a remote object. The remote object monitor can also monitor and/or control the lifetime of a remote object, using, for example, a lease manager. The remote object manipulator can also update metadata concerning a remote object and can control the lifetime of a remote object via a lease manager, for example.

Claims

1. A computer system that facilitates remoting services across application domains in a distributed object system, the system comprising:

a remote object monitor to monitor a remote object, the remote object imaged as a proxy object existing in a different application domain, a class that implements the proxy object being extensible through one or more attributes to provide attribute based code, wherein the remote object monitor is configured to monitor the remote object at least by intercepting client calls on the remote object, perform the attribute based code; and

determine a lifetime of the remote object, the remote object monitor to employ a lease to determine the lifetime of the remote object.

2. The system of claim 1, where the client calls on the remote object comprise a human readable reference to the remote object.

3. The system of claim 2, where the human readable reference to the remote object codes information comprising at least one of protocol information, protocol data, an application name and an object URI (Uniform Resource Identifier).

4. The system of claim 3, where the human readable reference to the remote object is a URL (Uniform Resource Locator).

5. The system of claim 3, where the protocol information is at least one of HTTP (Hypertext Transfer Protocol) information and SMTP (Simple Mail Transfer Protocol) information.

6. The system of claim 1, where the attribute based code is to be performed before non-attribute code associated with the proxy object.

7. The system of claim 1, where the attribute based code is to be performed in parallel with non-attribute code associated with the proxy object.

8. The system of claim 1, where the attribute based code is to be performed after non-attribute code associated with the proxy object.

9. The system of claim 1, where the attribute based code is to be performed at least one of before, in parallel with, and/or after non-attribute code associated with the proxy object.

10. The system of claim 1, where the lease further comprises a renew on access time.

11. A computer readable storage medium storing computer executable components to facilitate extending the class that implements the proxy object of the system of claim 1.
