How to see the native code?

Hi all,
I am very new to JNI. Actually i am doing a debugging task and has to understand the flow of the application.
I got a set of class files from which i decomplied the required class and got the java program. But that java file in turn calls a native method. It loads the .sl file in the static block.
I created the .h file from the class file and came to know that the native method is written in C++.
Is it possible to see what is written in that C++ native method? i posted the topic under JNI, but i didnot got any reply.

Is it possible to see what is written in that C++
native method?You can decompile it...
By the way: if you have to decompile something it means that you don't have the sources, which means to me that in most cases, the code isn't yours. Which means in many cases, this decompiling might be illegal.

But i want to view the complete code behind that tile like in MSA 5.0 when we right click on the tile-> view code.

How to see the ABAP Code behind SAP Exit Variables.

Hi Everyone.
I was wondering if anyone could help me with the steps to see the ABAP Code behind a SAP Exit Variable.
Sometime back I remember of going to Transaction SE37 - Function Module and give the Variable name,
Eg: 0F_ADAY, Hit F4 or something like that and was able to see the ABAP Code/Function Module/Exit written for that Variable.same
But today I tried to do the same thing to see the code for Variable 0P_FVAEX but I was NOT able to see it.
I think I am missing something.
Can someone help me recollect what I am missing.
Thank You for your time

How to see the procedure code ?

Hi all i have created a stored procedure .
How can i see the code of that procedure ?
I mean in which user_object is it stored ?
Srini

I did my stored function code several months ago, and accidently deleted it from my body of SQL/DDL files.That's why Nature gave us source control. Next time you may not be so lucky: the reason why you need to find the source might be because someone's dropped it from the database. Or they might have wrapped the code so the source is unreadable.
Of course, it maybe that rewriting a procedure results in a better, more elegant solution. I know I often feel that if only I had the time, I would love to rewrite large swathes of my current project. But, unlike the professor in Insignificance, few of us have the luxury. Obviously there are other benefits to source control other than not having to rewrite lost code (configuration management is the other main one). Whatever. A lot of people seem to like Subversion, perhaps because it's free.

I want to see the source code of JVM

Can anyone tell me how to see the source code of JVM, but not the src.zip that including in the java libraries. I just want to know how Java is implemented.
Thanks a lot for any answer.

You can get the source code (written in C++) of Sun's VM under the Community Licence arangement. Not sure quite where it is on this site, but if you look for it, I'm sure you'll find it.
BTW, it's not easy reading.

How do I see the source code for 'NI Example Finder'?

At the LabView Express demo, the rep showed us how to view the source code for 'NI Example Finder' (started with Help, Find Examples...). Please refresh my memory.
--todd

There are a couple of VI's that shipped with LabView 7.0, but you can't see the diagrams.
C:\Program Files\National Instruments\LabVIEW 7.0\resource\system\HelpServer.llb\Run Example Finder__NATIONAL INSTRUMENTS.vi
Press Ctrl-E on this VI and it prompts you for a password.
This VI is run by C:\Program Files\National Instruments\LabVIEW 7.0\resource\system\HelpServer.llb\HelpServer__NATIONAL INSTRUMENTS.vi
There's also C:\Program Files\National Instruments\LabVIEW 7.0\help\_exfinder.llb\Example Finder Launcher.vi.
Tyring to open this VI starts the NI Example Finder. Note the taskbar icon which is different from the normal VI icon.
It seems like NI is trying to keep us out, even if it used LabView to develop the Example Finder.

How do I see the source code in a Digital Edition doc?

First let me say that as an author, I'm a huGe fan of DRM and anything else that protects my ability to feed my family by allowing me to control who can sell my copyrighted works.
But.....I'm creating a book that I hope will eventually be accessed through Adobe Digital Editions and I would like to see what the books look like from the backside. Usually I go into Sigil to have a look at the coding of books whose layout I like.... but because of DRM I can't see the source code in any of the books in my Digital Library. So, is there a way to take a peek at the coding of a Digital Library book? I don't care about the content, only how the CSS and HTML are done.
Thanks

How to catch Exception inside the native code

Hello,
I have an error of unexpected exception during running native code,it occurrs randomly, not every time.
the error text is:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x9535F359
Function=acy_match+0xC6
Library=/usr/lib/libNegativeMatcher.so
I don't know what exactly cause the crash inside the c code but I think it might be memory leak . What I'm concern is that this exception cause program termination.
I have few questions:
1. This exception cause the java program to end. How can I catch this exception and avoid program termination?
2. What is 0xC6 in:
Function=acy_match+0xC6
and PC=0x9535F359?
Can it help me track the problem inside the native code?
Thanks for your help.

code outside the VM.
Unexpected Signal : 11 occurred at PC=0x9535F359

I don't know what exactly cause the crash inside the

termination.I doubt it is a memory leak (actually I am rather certain that another error would occur if it was just memory exhaustion.)
I have few questions:
1. This exception cause the java program to end. How
can I catch this exception and avoid program
termination?I suspect that would be a really bad idea. That particular signal very likely indicates that you have corrupted memory. Continuing is unlikely to work.
2. What is 0xC6 in:
As a guess it is an offset into the compiled code which indicates where the memory problem was detected.
That it unlikely to help you with a pointer/memory problem because that is where it was detected and not where it happened. By comparing the source you might be able to determine what was bad and then trace it back.
