Abstract

This invention describes a system and method for monitoring the execution of hybrid source code such as JavaServer Pages (JSP) code. The system comprises a page compiler, which is called by a server for translating JSP code into a servlet for execution by the server. The page compiler during translation of the JSP code inserts instrumentation in the compiled JSP code for supporting execution tracing by an execution monitor. The execution monitor receives outputs from the page compiler, the servlet and the raw JSP code for displaying selected information about the execution of the JSP code to the developer on a graphical user interface. The execution monitor thus allows the developer to view the correlation between the JSP code, the servlet code and the HTML code that is generated by the servlet.

Claims

1. A method for monitoring the execution of hybrid source code which is executable on a server, comprising the steps of:

generating executable code for execution by the server from the hybrid source code included in a single hybrid source code file comprising a source code in a second language imbedded in a source code of a markup language;

providing instrumentation in the executable code for supporting execution tracing; and

receiving in an execution monitor information from the instrumentation in the executable code for display on a user interface.

2. The method of claim 1 wherein the step of generating executable code comprises translating the hybrid source code into source code.

3. The method of claim 2 wherein the step of providing instrumentation comprises inserting instrumentation into the source code.

4. The method of claim 3 wherein the instrumentation comprises a mapping table comprising information correlating a code segment in the hybrid source code with a line in the source code.

5. The method of claim 4 wherein the instrumentation further comprises a line method for communicating said correlating information to the execution monitor.

6. The method of claim 2 further comprising displaying on the user interface the hybrid source code and the source code.

7. The method of claim 2 further comprising correlating a code segment from the hybrid source code with one or more lines of code from the source code using the instrumentation.

8. The method of claim 1 wherein the hybrid source code is JavaServer Pages code.

9. A method for monitoring execution of hybrid source code which executes in a server, comprising the steps of:

translating the hybrid source code by a page compiler into a source code form and an executable code;

providing methods into the executable code, such that when the server executes the executable code, the methods are invoked and send line information to an execution monitor allowing the execution monitor to synchronize an executing code segment of the hybrid source code with a corresponding line of the source code; and

displaying the executing code segment of the hybrid source and the corresponding line of the source code in a user interface.

10. A program storage device readable by a data processing system, tangibly embodying a program of instructions, executable by the data processing system to perform a method for monitoring the execution of hybrid source code which is executable on a seer, the method comprising the steps of:

generating executable code for execution by the server from the hybrid source code included in a single hybrid source code file comprising a source code in a second language imbedded in a source code of a markup language;

providing instrumentation in the executable code for supporting execution tracing; and

receiving in an execution monitor information from the instrumentation in the executable code for display on a user interface.

11. A computer program product for monitoring the execution of hybrid source code which is executable on a server, said computer program product comprising:

a page compiler for reading and translating the hybrid source code included in a single hybrid source code file comprising a source code in a second language imbedded in a source code of a markup language into executable code for execution by the server and for inserting instrumentation in the executable code for supporting execution tracing; and

an execution monitor for receiving information from the instrumentation in the executable code for display on a user interface.

12. A computer program product for displaying the execution of hybrid source code which is executable on a server, comprising:

a page compiler for translating the hybrid source code included in a single hybrid source code file comprising a source code in a second language imbedded in a source code of a markup language, inserting instrumentation for execution tracing in source code translated from the hybrid source code and compiling the hybrid source code into executable code for execution by the server; and

an execution monitor for receiving as input and for displaying in a user interface of the execution monitor, the hybrid source code, the source code, and information from the instrumentation in the executable code.

13. The computer program product of claim 12 further comprising a server for executing the executable code provided by the page compiler, and providing the information from the instrumentation in the executable code to the execution monitor.

14. The computer program product of claim 13 further comprising a browser for sending a request with respect to the hybrid source code, wherein the server further invokes the page compiler in response to the request and provides an output from the executable code to the browser.

15. The computer program product of claim 13 wherein the execution monitor further receives output from the executable code and wherein the server provides the output from the executable code to the execution monitor.

16. The computer program product of claim 13 further comprising bi-directional communication means for communicating between the executable code and the execution monitor including communicating the information from the instrumentation in the executable code to the execution monitor.

17. The computer program product of claim 13 wherein the hybrid source code is JavaServer Pages code.

18. A computer system for monitoring the execution of hybrid source code which is executable on a server, said computer system comprising:

a page compiler for reading and translating the hybrid code included in a single hybrid source code file comprising a source code in a second language imbedded in a source code of a markup language into executable code for execution by the server and for inserting instrumentation in the executable code for supporting execution tracing;

an execution monitor for receiving information from the instrumentation in the executable code for display on a user interface.

19. A computer system for displaying the execution of hybrid source code which is executable on a server, comprising:

an execution monitor for receiving as input and for displaying in a user interface of the execution monitor, the hybrid source code, the source code, and information from the instrumentation in the executable code.

20. The computer system of claim 19 further comprising a server for executing the executable code provided by the page compiler, and providing the information from the instrumentation in the executable code to the execution monitor.

21. The computer system of claim 20 further comprising a browser for sending a request with respect to the hybrid source code, wherein the server further invokes the page compiler in response to the request and provides an output from the executable code to the browser.

22. The computer system of claim 20 wherein the execution monitor further receives output from the executable code and wherein the server provides the output from the executable code to the execution monitor.
