System and method for visualizing exception generation

1. A method of graphically animating program exceptions, comprising:

executing an application program during a server session including a plurality of analysis windows;

monitoring, on an exception monitoring system, said application program for a thrown exception;

responsive to said thrown exception, logging, by the exception monitoring system, exception data to an exception table;

responsive to conclusion of each analysis window, appending, by the exception monitoring system, said exception table to a log file;

upon ending said server session, building, by the exception monitoring system, an analysis database for rendering an exception visualization animation to a user,

wherein said exception visualization animation maps exception information into a graphical representation of a program structure; and

wherein said thrown exception includes information about a class from which said thrown exception originated.

2. The method of claim 1 , said exception data comprising an index value, a count of number of exception instances, a time of last throw of said exception instance, exception class indicia, exception source indicia, and probe identifier.

3. The method of claim 2 , said analysis database including for each table a plurality of rows of exception data, with a row for each unique exception-source tuple including table number, index indicia, count of occurrences, exception indicia, and source of exception indicia.

4. The method of claim 3 , said visualization animation including a plurality of exception renditions corresponding to said exception tables, each exception rendition including indicia representative of the number of occurrences of said exception, a modification flag, said exception indicia and said source of exception indicia.

5. The method of claim 4 , said modification flag being set for each exception-source tuple of an exception table having exception activity during an analysis window corresponding to said exception table, said activity including one or more of: a new exception and an exception having its count increased.

6. The method of claim 5 , said visualization animation comprising a sequence of table renditions.

7. The method of claim 5 , said visualization animation comprising a sequence of universal modeling language (UML) class diagrams.

8. A system for graphically animating exceptions thrown by an application, comprising:

a processor;

an application server;

an application program;

an in-memory exception table;

an exception log file;

an analysis database; and

a user interface;

said application server for executing said application program during a server session including a plurality of analysis windows;

responsive to exceptions thrown by said application program during execution for logging exception data to said in-memory exception table;

responsive to completing an analysis window, logging said exception table to said exception log file;

responsive to completing said server session, for building an analysis database from said exception log file;

generating from said exception log file an exception visualization animation including a sequential plurality of exception table renditions to said user interface, wherein said exception visualization animation maps exception information into a graphical representation of a program structure; and

wherein said exceptions include information about a class from which one or more of said exceptions originated.

9. The system of claim 8 , said exception data comprising an index value, a count of number of exception instances, a time of last throw of said exception instance, exception class indicia, exception source indicia, and probe identifier.

10. The system of claim 9 , said analysis database including for each table a plurality of rows of exception data, with a row for each unique exception-source tuple including table number, index indicia, count of occurrences, exception indicia, and source of exception indicia.

11. The system of claim 10 , said visualization animation including a plurality of exception renditions corresponding to said exception tables, each exception rendition including indicia representative of the number of occurrences of said exception, a modification flag, said exception indicia and said source of exception indicia.

12. The system of claim 11 , said modification flag being set for each exception-source tuple of an exception table having exception activity during an analysis window corresponding to said exception table, said activity including either one or more of a new exception and an exception having its count increased.

13. The system of claim 12 , said visualization animation comprising a sequence of table renditions.

14. The system of claim 12 , said visualization animation comprising a sequence of universal modeling language (UML) class diagrams.

15. A program storage device readable by a machine, tangibly embodying a program of instructions executable by a machine to perform operations for graphically animating program exceptions, said operations comprising:

executing an application program during a server session including a plurality of analysis windows;

monitoring said application program for a thrown exception;

responsive to said thrown exception, logging exception data to an exception table;

responsive to conclusion of each analysis window, appending said exception table to a log file; and

upon ending said server session, building an analysis database for rendering exception visualization animation to a user, wherein said exception visualization animation maps exception information into a graphical representation of a program structure; and

wherein said thrown exception includes information about a class from which said thrown exception originated.

16. The program storage device of claim 15 , said exception data comprising an index value, a count of number of exception instances, a time of last throw of said exception instance, exception class indicia, exception source indicia, and probe identifier.

17. The program storage device of claim 16 , said analysis database including for each table a plurality of rows of exception data, with a row for each unique exception-source tuple including table number, index indicia, count of occurrences, exception indicia, and source of exception indicia.

18. The program storage device of claim 17 , said visualization animation including a plurality of exception renditions corresponding to said exception tables, each exception rendition including indicia representative of the number of occurrences of said exception, a modification flag, said exception indicia and said source of exception indicia.

19. The program storage device of claim 18 , said modification flag being set for each exception-source tuple of an exception table having exception activity during an analysis window corresponding to said exception table, said activity including one or more of a new exception and an exception having its count increased.

20. The program storage device of claim 19 , said visualization animation comprising a sequence of table renditions.

21. The program storage device of claim 19 , said visualization animation comprising a sequence of universal modeling language (UML) class diagrams.
