Abstract
Abstract A software system is disclosed which provides for dynamic generation of remote proxy classes at run time through a distributed object management system 16 . The software system provides for a client system 14 and server system 12 which communicate via distributed object management system 16 which operates over a distributed computer network to allow communications between client system 14 and server system 12 . Any inter-object communication will invoke a remote proxy generation control module 34 if a remote proxy class 23 does not already exist for the requested subject object 18 . A remote proxy generation control module 34 is provided which first invokes reflection engine 36 to determine the applicable information of subject class 19 . Next, a communication enabling module 40 determines and inserts the appropriate computer code to allow local object 20 to communicate with subject object 18 utilizing remote proxy object 22 . After the system determines what information is required by remote proxy class 23 , byte code generator 42 automatically generates the executable code containing remote proxy class 23 . Finally, class loader 46 loads remote proxy class 23 onto the system and creates a new instance which is remote proxy object 22.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
107 words
A proxy generator for generating a proxy class in a computer environment, comprising: a control module operable to receive an access request from a requesting object in a first address space, the access request identifying a requested object in a second address space, the control module operable to facilitate communications between the requesting object in the first address space and the requested object in the second address space; a reflection engine operable to determine a structure of the requested object for use in creating the proxy class; a byte code generator operable to generate computer code for the proxy class representing the structure of the requested object.
Claim 2
Dependent Claim
107 words
A proxy generator for generating a proxy class in a computer environment, comprising: a control module operable to receive an access request from a requesting object in a first address space, the access request identifying a requested object in a second address space, the control module operable to facilitate communications between the requesting object in the first address space and the requested object in the second address space; a reflection engine operable to determine a structure of the requested object for use in creating the proxy class; a byte code generator operable to generate computer code for the proxy class representing the structure of the requested object.
