Abstract

Claims (49)

1. A computer-implemented method for enabling a viewer to perform screen sharing, the method comprising:

transmitting, to a browser of the viewer, a script configured to (i) display a sequence of images sourced from a browser of a presenter, via the file server, on the viewer's browser in response to control of the sequence by the presenter, and (ii) in response to a request for a screen sharing executable from the viewer, generate a download request including a system type and one or more identification parameters;

wherein the script displays the sequence of images on the viewer's browser without requiring the viewer's browser to run an applet;

receiving, at the file server, the download request from the script;

locating, using the file server, a pre-compiled payload suitable for execution on a computer of the viewer based on the system type;

determining, using the file server, a configuration data for use with the pre-compiled payload based on the one or more identification parameters; and

generating, using the file server, a customized executable file for the viewer to download, wherein the customized executable file includes the pre-compiled payload and the configuration data, wherein the pre-compiled payload, upon being executed, establishes a virtual machine to execute bytecode programs, and wherein the bytecode programs include a sharing applet that causes the file server to relay screen images of the viewer from the viewer, through the file server, to a presenter.

2. The method of claim 1 , wherein the locating comprises:

decompressing a first archive to extract the pre-compiled payload and a meta compression information.

3. The method of claim 2 , wherein the selective generating is based on the system type and comprises:

if the system type is a first type that needs an executable self-extractor,

(i) compressing the pre-compiled payload and the configuration data into a second archive; and

(ii) appending the second archive and the meta compression information to a self-extracting stub file to create the customized executable file.

4. The method of claim 2 , wherein the selective generating is based on the system type and comprises:

if the system type is a second type that does not need an executable self-extractor, compressing the pre-compiled payload and the configuration data into a second archive to create the customized executable file.

5. The method of claim 1 , wherein the customized executable file, upon being executed on the viewer, facilitates the viewer in sharing screen images of the viewer via the pre-compiled payload, through a screen sharing server, to the presenter.

6. The method of claim 5 , wherein the file server comprises the screen sharing server.

7. The method of claim 1 , wherein the pre-compiled payload and the sharing applet are automatically configured according to the configuration data.

8. A system for generating files, the system comprising:

a processor; and

a memory coupled to the processor and storing a plurality of instructions which, when executed by the processor, cause the processor to:

transmit, to a browser of the viewer, a script configured to (i) display a sequence of images sourced from a browser of a presenter, via the file server, on the viewer's browser in response to control of the sequence by the presenter, and (ii) in response to a request for a screen sharing executable from the viewer, generate a download request including a system type and one or more identification parameters;

wherein the script displays the sequence of images on the viewer's browser without requiring the viewer's browser to run an applet;

receive the download request from the script;

locate a pre-compiled payload suitable for execution on a computer of the viewer based on the system type;

determine a configuration data for use with the pre-compiled payload based on the one or more identification parameters; and

generate a customized executable file for the viewer to download, wherein the customized executable file includes the pre-compiled payload and the configuration data, wherein the pre-compiled payload, upon being executed, establishes a virtual machine to execute bytecode programs, and wherein the bytecode programs include a sharing applet that causes the file server to relay screen images of the viewer from the viewer, through the file server, to a presenter.

9. The system of claim 8 , wherein the instructions further cause the processor to:

decompress a first archive to extract the pre-compiled payload and a meta compression information.

10. The system of claim 9 , wherein the processor generates based on the system type, and wherein the instructions further cause the processor to:

if the system type is a first type that needs an executable self-extractor,

(i) compress the pre-compiled payload and the configuration data into a second archive; and

(ii) append the second archive and the meta compression information to a self-extracting stub file to create the customized executable file.

11. The system of claim 9 , wherein the processor generates based on the system type, and wherein the instructions further cause the processor to:

if the system type is a second type that does not need an executable self-extractor, compress the pre-compiled payload and the configuration data into a second archive to create the customized executable file.

12. The system of claim 8 , wherein the customized executable file, upon being executed on the viewer, facilitates the viewer in sharing screen images of the viewer via the pre-compiled payload, through a screen sharing server, to the presenter.

13. The system of claim 12 , wherein the file server comprises the screen sharing server.

14. The system of claim 8 , wherein the pre-compiled payload and the sharing applet are automatically configured according to the configuration data.

15. A non-transitory storage medium storing a plurality of instructions which, upon being loaded into a memory of a server, cause the server to:

transmit, to a browser of the viewer, a script configured to (i) display a sequence of images sourced from a browser of a presenter, via the file server, on the viewer's browser in response to control of the sequence by the presenter, and (ii) in response to a request for a screen sharing executable from the viewer, generate a download request including a system type and one or more identification parameters;

wherein the script displays the sequence of images on the viewer's browser without requiring the viewer's browser to run an applet;

receive the download request from the script;

locate a pre-compiled payload suitable for execution on a computer of the viewer based on the system type;

decompress a first archive to extract the pre-compiled payload and a meta compression information;

determine a configuration data for use with the pre-compiled payload based on the one or more identification parameters; and

generate a customized executable file for the viewer to download based on the system type, wherein the customized executable file includes the pre-compiled payload and the configuration data.

16. The medium of claim 15 , further causes the server to:

if the system type is a first type that needs an executable self-extractor, (i) compress the pre-compiled payload and the configuration data into a second archive; and (ii) append the second archive and the meta compression information to a self-extracting stub file to create the customized executable file; and

if the system type is a second type that does not need an executable self-extractor, compress the pre-compiled payload and the configuration data into a third archive to create the customized executable file.
