Hello everyone,
I am wondering if I want to debug JNI application (upper layer Java and lower layer C), are there any tools to debug through Java code to C code and return back from C code to Java code.
I am using Eclipse. But I do not find such functions in Eclipse (maybe I miss some plug-ins?). Currently, I can only debug Java code.
thanks in advance,
George
Have you tried debugging the native object in a C ide first? The interface from Java to C tends to be pretty simple... If you are happy with what is going on in Java, then it seems like the sensible step?
Thanks alpha_foobar,

You mean there is no integrated way to debug Java part and C part -- debugging goes through Java code into C code and vice versa?

George
I'm not aware of any. But it isn't an area I have spent a lot of time in.
I'd suspect that you'd need the dll to be running in a C IDE in debug mode for a seamless debug thread to work. And I don't really think that would be possible.
Are you having a problem with something - or is this more of a theoretic question? I'm just thinking that if debugging the C module separately isn't a feasible solution - perhaps there is another way more specific to your problem?

It is my interest to learn and try new ways and new technology. I am learning JNI and I want to study how to debug and solve issues in JNI code.
How to debug the C module separately? I need to know the input parameters from Java code, right?

Hi George2,
Let's me introduce Eclipse* based tool for debugging Java*/JNI environment that uses CDT and JDT perspectives makes developer works comfortable for Eclipse* users and moving out two debugger scenario to the history.
Please find time to visit http://softwarecommunity.intel.com/articles/eng/1435.htm and try it. Let us to know if it helps to you or not, and what changes should be done to meet your expectations and requirements.
