Abstract

Methods, apparatus and a computer program product are provided for implementing enhanced server page execution. A predefined file or a predefined directory is monitored for change. Responsive to identifying a change in the predefined file or the predefined directory, a server page is monitored for change. Checking the server page for change with each use is eliminated, thereby speeding up run time execution of the server page. Monitoring the predefined file or predefined directory for change can include providing a trigger function with the file or with a directory entity for the predefined directory; the trigger function to identify a change within the predefined directory. Alternatively, monitoring the predefined file or the predefined directory for change includes providing a daemon program for monitoring the predefined file or predefined directory for activity. A META tag can be used for governing when the server page is set to be monitored for change. The META tag can be used with the trigger function or with the daemon program.

Claims

1. A computer-implemented method for implementing enhanced server page execution comprising the steps of:

loading a server page;

monitoring a predefined file or a predefined directory for change;

responsive to identifying a change in said predefined file or said predefined directory, setting a check bit on for monitoring said server page for change; and

receiving an action to run said server page and responsive to said check bit being off, running said server page without checking said server page for change.

2. A computer-implemented method for implementing enhanced server page execution as recited in claim 1 wherein the step of monitoring said predefined directory for change includes the step of providing a trigger function with said predefined file or with a directory entity for said predefined directory;

said trigger function to identify a change within said predefined file or said predefined directory.

3. A computer-implemented method for implementing enhanced server page execution as recited in claim 2 wherein said trigger function is called by an operating system when an associated server page file has been modified upon close of file.

4. A computer-implemented method for implementing enhanced server page execution as recited in claim 2 wherein said trigger function is called by a trigger list included in a directory entity when an associated file with said directory entity is changed.

5. A computer-implemented method for implementing enhanced server page execution as recited in claim 1 wherein the step of monitoring said predefined file or said predefined directory for change includes the step of providing a daemon program for monitoring said predefined file or said predefined directory for activity.

6. A computer-implemented method for implementing enhanced server page execution as recited in claim 5 wherein the step of providing said daemon program for monitoring said predefined directory for activity includes the steps of monitoring for a file change for each directory in a class path and for each server page.

7. A computer-implemented method for implementing enhanced server page execution as recited in claim 5 includes the steps responsive to an identified file change, sending a filed changed action to a servlet engine;

and said servlet engine monitoring said server page for change.

8. A computer-implemented method for implementing enhanced server page execution as recited in claim 1 wherein the step of monitoring said predefined file or said predefined directory for change includes the step of providing a META tag within said server page;

said META tag for governing when said server page is set to be monitored for change.

9. A computer-implemented method for implementing enhanced server page execution as recited in claim 1 wherein said predefined directory includes a file system directory structure;

said file system directory structure including a plurality of directories.

10. A computer program product for implementing enhanced server page execution in a computer system including a central processor unit, said computer program product including a plurality of computer executable instructions stored on a computer readable medium, wherein said instructions, when executed by said central processor unit, cause the central processor unit to perform the steps of:

executing a server page;

monitoring a predefined file or a predefined directory for change

responsive to identifying a change in said predefined file or said predefined directory, setting a check bit on for monitoring said server page for change; and

receiving an action to run said server page and responsive to said check bit being off, running said server page without checking said server page for change.

11. A computer program product for implementing enhanced server page execution as recited in claim 10 wherein said predefined directory includes a file system directory structure;

said file system directory structure including a plurality of directories.

12. A computer program product for implementing enhanced server page execution as recited in claim 10 wherein the step of monitoring said predefined directory for change includes the step of providing a trigger function with said predefined file or with a directory entity for said predefined directory;

said trigger function to identify a change within said predefined file or said predefined directory.

13. A computer program product for implementing enhanced server page execution as recited in claim 10 wherein the step of monitoring said predefined directory for change includes the step of providing a daemon program for monitoring said predefined file or said predefined directory for activity.

14. A computer program product for implementing enhanced server page execution as recited in claim 10 wherein the step of monitoring said predefined file or said predefined directory for change includes the step of providing a META tag within said server page;

said META tag for governing when said server page is set to be monitored for change.

15. Apparatus for implementing enhanced server page execution comprising:

a servlet engine for executing a server page;

a file system monitoring program for monitoring a predefined file or a predefined directory for change and for notifying said servlet engine of an identified change in said predefined file or said predefined directory;

said servlet engine responsive to said identified change, for setting a check bit on for monitoring said server page for change; and

said servlet engine responsive to receiving an action to run said server page and responsive to said check bit being off, running said server page without checking said server page for change.

16. Apparatus for implementing enhanced server page execution as recited in claim 15 wherein said file system monitoring program includes a trigger function provided with a directory entity for said predefined directory;

said trigger function to identify a change within said predefined file or said predefined directory.

17. Apparatus for implementing enhanced server page execution as recited in claim 15 wherein said file system monitoring program includes a daemon program for monitoring said predefined file or said predefined directory for activity.

18. Apparatus for implementing enhanced server page execution as recited in claim 15 wherein said file system monitoring program includes a META tag provided within said server page;

said META tag for governing when said server page is set to be monitored for change.

19. Apparatus for implementing enhanced server page execution as recited in claim 15 wherein said predefined directory includes a file system directory structure;

said file system directory structure including a plurality of directories.
