JNI Java and C Problem

[Theo]

Hi.

I have the following problem. I have an application (with sources)
completely written in C. Now I want to write an Java application with
possibility to exchange data (int, double, String ...) with my CApp. I
have read the JNI tutorial and many posts in many forums.
I can start the JavaApp out of my CApp and give over some data. But I
want to provide some data to my CApp when I press a button for example.


My operating system is a linux debian distribution.

Thanx for any help.
Theo

So whats the problem? Define a native java method, call javah,
implement the body in C, compile, load .so in java, and call your method
when the button is pushed.
