Abstract

A method of dynamically communicating a parameter during runtime may include providing a script to a command-line scripting module that uses the parameter, where the parameter is to be provided during runtime by a user and the script is configured to generate an exception including an identifier associated with the parameter. The method may also include generating byte code based on the script, executing the byte code on a virtual machine until the exception is generated, passing the exception to the command-line scripting module, causing, by the command-line scripting module, receiving a parameter value from the user through an input device, passing the parameter value to the virtual machine, and continuing execution of the byte code on the virtual machine.

Claims

1. A method of dynamically communicating a parameter during runtime, the method comprising:

providing a script to a command-line scripting module, wherein;

the script uses the parameter;

the parameter is to be provided during runtime by a user; and

the script is configured to generate an exception associated with the parameter, wherein the exception comprises a parameter identifier;

generating byte code based on the script;

executing the byte code on a virtual machine until the exception is generated, wherein the virtual machine operates on a Enterprise computer system;

passing the exception to the command-line scripting module;

causing, by the command-line scripting module, the parameter identifier to be communicated to the user using a display device;

receiving a parameter value from the user through an input device;

passing the parameter value to the virtual machine; and

continuing execution of the byte code on the virtual machine.

2. The method of claim 1 wherein the script comprises JYTHON code, and wherein the byte code comprises JAVA byte code.

3. The method of claim 1 wherein the byte code is generated using a specialized compiler to recognize code segments requesting the parameter in the script.

4. The method of claim 1 wherein the command-line scripting module operates on a first computer system, and wherein the virtual machine operates on a second computer system, wherein the first computer system is geographically remote from the second computer system.

5. The method of claim 1 wherein the parameter comprises a password.

6. The method of claim 1 wherein the script comprises initial parameters provided prior to runtime.

7. The method of claim 1 wherein the parameter comprises a plurality of parameters, and wherein the method further comprises receiving parameter values for each of the plurality of parameters from the user through the input device.

8. The method of claim 7 wherein each of the plurality of parameters is associated with its own exception.

9. The method of claim 7 wherein each of the plurality of parameters is associated with the same exception.

10. The method of claim 7 wherein a size of the plurality of parameters is determined by at least one of the plurality of parameters at runtime.

11. A computer-readable memory having stored thereon a sequence of instructions which, when executed by one or more processors, causes the one or more processors to dynamically communicate a parameter during runtime by:

providing a script to a command-line scripting module, wherein;

the script uses the parameter;

the parameter is to be provided during runtime by a user; and

the script is configured to generate an exception associated with the parameter, wherein the exception comprises a parameter identifier;

generating byte code based on the script;

executing the byte code on a virtual machine until the exception is generated, wherein the virtual machine operates on a Enterprise computer system;

passing the exception to the command-line scripting module;

causing, by the command-line scripting module, the parameter identifier to be communicated to the user using a display device;

receiving a parameter value from the user through an input device;

passing the parameter value to the virtual machine; and

continuing execution of the byte code on the virtual machine.

12. The computer-readable memory according to claim 11 wherein the script comprises JYTHON code, and wherein the byte code comprises JAVA byte code.

13. The computer-readable memory according to claim 11 wherein the byte code is generated using a specialized compiler to recognize code segments requesting the parameter in the script.

14. The computer-readable memory according to claim 11 wherein the parameter comprises a password.

15. The computer-readable memory according to claim 11 wherein the parameter comprises a plurality of parameters, and wherein the method further comprises receiving parameter values for each of the plurality of parameters from the user through the input device.

16. The computer-readable memory according to claim 15 wherein each of the plurality of parameters is associated with its own exception.

17. The computer-readable memory according to claim 15 wherein each of the plurality of parameters is associated with the same exception.

18. A system comprising:

one or more processors; and

a memory communicatively coupled with and readable by the one or more processors and having stored therein a sequence of instructions which, when executed by the one or more processors, cause the one or more processors to dynamically communicate a parameter during runtime by;

providing a script to a command-line scripting module, wherein;

the script uses the parameter;

the parameter is to be provided during runtime by a user; and

the script is configured to generate an exception associated with the parameter, wherein the exception comprises a parameter identifier;

generating byte code based on the script;

executing the byte code on a virtual machine until the exception is generated, wherein the virtual machine operates on a Enterprise computer system;

passing the exception to the command-line scripting module;

causing, by the command-line scripting module, the parameter identifier to be communicated to the user using a display device;

receiving a parameter value from the user through an input device;

passing the parameter value to the virtual machine; and

continuing execution of the byte code on the virtual machine.

19. The system of claim 18 wherein the script comprises JYTHON code, and wherein the byte code comprises JAVA byte code.

20. The system of claim 18 wherein the byte code is generated using a specialized compiler to recognize code segments requesting the parameter in the script.
