Abstract

Development using the JavaScript programming language can be limited since JavaScript code is interpreted. Compiling code at a client may interfere with the dynamicity and portability of web pages. Dynamicity and portability of web pages can be preserved while providing the features of a compiled programming language. A compiled programming language code can be embedded within an interpreted programming language code. The embedded compiled programming language code can be extracted and compiled with resources of a server to deliver the robustness and flexibility of the compiled programming language without burdening a client with compiling.

Claims

1. A method comprising:

a web server receiving a request from a web client for a webpage that indicates an interpreted programming language code;

determining that a compiled programming language code is embedded in the interpreted programming language code;

compiling the embedded compiled programming language code to generate executable code;

associating a service with the executable code, wherein the service runs the executable code when called;

replacing the embedded compiled programming language code with a call to the service; and

supplying to the web client the interpreted programming language code with the call to the service.

2. The method of claim 1, wherein the interpreted programming language code is at least one of embedded in the HyperText Markup Language of the webpage, and within a file referenced by the webpage.

3. The method of claim 1, wherein said determining that the compiled programming language code is embedded in the interpreted programming language code comprises at least one of examining the interpreted programming language code for special tags or metadata and examining a file extension in a reference of the webpage.

4. The method of claim 1 further comprising generating a compiled programming language class based on the embedded compiled programming language code.

5. The method of claim 4, further comprising recognizing tokens within the embedded compiled programming language code, wherein said generating the compiled programming language class is based, at least in part, on said recognizing.

6. The method of claim 1 further comprising the service running the executable code in response to the web client executing the service call.

7. The method of claim 6 further comprising returning one or more results to the web client based on running the executable code.

8. The method of claim 1, wherein the service comprises an AJAX service.

9. A method comprising:

a web server detecting execution of a service call by a web client, wherein the service call is associated with executable code generated from compiling Java code extracted from JavaScript code and replaced with the service call, wherein the JavaScript code corresponds to a web page requested by the web client;

executing the executable code; and

returning one or more results to the web client based on executing the executable code.

10. One or more machine-readable media having stored therein a program product, which when executed by a set of one or more processor units causes the set of one or more processor units to perform operations that comprise:

a web server receiving a request from a web client for a webpage that indicates an interpreted programming language code;

determining that a compiled programming language code is embedded in the interpreted programming language code;

compiling the embedded compiled programming language code to generate executable code;

associating a service with the executable code, wherein the service runs the executable code when called;

replacing the embedded compiled programming language code with a call to the service; and

supplying to the web client the interpreted programming language code with the call to the service.

11. The machine-readable media of claim 10, wherein the interpreted programming language code is at least one of embedded in the HyperText Markup Language of the webpage, and within a file referenced by the webpage.

12. The machine-readable media of claim 10, wherein said determining that the compiled programming language code is embedded in the interpreted programming language code comprises at least one of examining the interpreted programming language code for special tags or metadata and examining a file extension in a reference of the webpage.

13. The machine-readable media of claim 10, wherein the operations further comprise generating a compiled programming language class based on the embedded compiled programming language code.

14. The machine-readable media of claim 13, wherein the operations further comprise recognizing tokens within the embedded compiled programming language code, wherein said generating the compiled programming language class is based, at least in part, on said recognizing.

15. The machine-readable media of claim 10, wherein the operations further comprise the service running the executable code in response to the web client executing the service call.

16. The machine-readable media of claim 15, wherein the operations further comprise returning one or more results to the web client based on running the executable code.

17. The machine-readable media of claim 10, wherein the service comprises an AJAX service.

18. An apparatus comprising:

a set of one or more processing units;

a network interface; and

an embedded compiled programming language code processing unit operable to,

receive a request from a web client for a webpage that indicates an interpreted programming language code;

determine that a compiled programming language code is embedded in the interpreted programming language code;

compile the embedded compiled programming language code to generate executable code;

associate a service with the executable code, wherein the service runs the executable code when called;

replace the embedded compiled programming language code with a call to the service; and

supply to the web client the interpreted programming language code with the call to the service.

19. The apparatus of claim 18, wherein said the embedded compiled programming language code processing unit being operable to determine that the compiled programming language code is embedded in the interpreted programming language code comprises the embedded compiled programming language code processing unit being operable to at least one of examine the interpreted programming language code for special tags or metadata and detect a file extension in a reference of the webpage.

20. The apparatus of claim 18, wherein the embedded compiled programming language code processing unit comprises one or more machine-readable media.
