Abstract

A method and system for executing calls and return calls using client interfaces for packages. In one embodiment, a service at a service package is called using a client interface at a client package. The return call is then made on object using the client interface at the client package as performed by the service at the service package.

Claims

1. A method comprising:

locating an access object assigned to a first service of a service package at a service computer system, the service including a call to access a content of a client package at a client computer system that is coupled to the service computer system, wherein

the access object is accessible to the client package via a service interface,

the content of the client package is accessible via the access object,

the call included in the service identifies a second service of the service package inaccessible to the client package via the service interface and the client package interface, and

the client package includes a dependency control list and a dependency log of objects used by the client package, the dependency control list to control access to the client package interface, and the dependency log to log static and dynamic uses of objects;

accessing the content of the client package via the access object;

calling, via the content of the client package, the call included in the service; and

return calling, by the service call of the service, the content of the client package to establish a dynamic connection between the client package and the second service of the service package.

2. The method of claim 1, further comprising:

assigning an additional service package to the access object, wherein the service package and the additional service package include a list of objects assigned to each respective service package; and

aggregating the lists of the service packages assigned to the access object.

3. The method of claim 2, further comprising exposing the access object to the client package.

4. The method of claim 1, further comprising:

creating the client interface at the client package using the access object.

5. A system comprising:

means for locating an access object assigned to a first service of a service package at a service computer system, the service including a call to access a content of a client package at a client computer system that is coupled to the service computer system, wherein

the access object is accessible to the client package via a service interface,

the content of the client package is accessible via the access object,

the call included in the service identifies a second service of the service package inaccessible to the client package via the service interface and the client package interface, and

the client package includes a dependency control list and a dependency log of objects used by the client package, the dependency control list to control access to the client package interface, and the dependency log to log static and dynamic uses of objects;

means for accessing the content of the client package via the access object;

means for calling, via the content of the client package, the call included in the service; and

means for return calling, by the service call of the service, the content of the client package to establish a dynamic connection between the client package and the second service of the service package.

6. The system of claim 5, further comprising:

means to assign an additional service package to the access object, wherein the service package and the additional service package include a list of objects assigned to each respective service package; and

means to aggregate the lists of the service packages assigned to the access object.

7. The system of claim 6, further comprising means to expose the access object to the client package.

8. The system of claim 5, wherein the client package is further to:

create the content interface at the client package using the access object.

9. A machine-readable storage medium having stored thereon data representing sets of instructions which, when executed by a machine, cause the machine to:

locate an access object assigned to a first service of a service package at a service computer system, the service including a call to access a content of a client package at a client computer system that is coupled to the service computer system, wherein

the access object is accessible to the client package via a service interface,

the content of the client package is accessible via the access object,

the call included in the service identifies a second service of the service package inaccessible to the client package via the service interface and the client package interface, and

the client package includes a dependency control list and a dependency log of objects used by the client package, the dependency control list to control access to the client package interface, and the dependency log to log static and dynamic uses of objects;

accessing the content of the client package via the access object;

call, via the content of the client package, the call included in the service; and

return call, by the service call of the service, the content of the client package to establish a dynamic connection between the client package and the second service of the service package.

10. The machine-readable storage medium of claim 9, wherein the sets of instructions which, when executed by the machine, cause the machine to:

assign an additional service package to the access object, wherein the service package and the additional service package include a list of objects assigned to each respective service package; and

aggregate the lists of the service packages assigned to the access object.

11. The machine-readable storage medium of claim 9, wherein the sets of instructions which, when executed by the machine, cause the machine to:

create the content interface at the client package using the access object.

12. The machine-readable storage medium of claim 9, wherein the sets of instructions which, when executed by the machine, cause the machine facilitate the client package to request the service at the service package.
