In Ubuntu 12.04, I have jdk7 from sun/oracle installed. When locate jni.h, it prints multiple locations 

/usr/lib/jvm/java-6-openjdk-amd64/include/jni.h
/usr/lib/jvm/jdk1.7.0_07/include/jni.h
...

In the header file generated by JDK, there is include <jni.h>, and currently it complains 

fatal error: jni.h: No such file or directory.

In my Makefile, there is no specification of locations where jni.h is. And I am asking if possible to configure certain system parameter to make path of jni.h (say, /usr/lib/jvm/jdk1.7.0_07/include/jni.h) to be known when being compiled.

You have to tell your compiler where is the include directory. Something like this:

gcc -I/usr/lib/jvm/jdk1.7.0_07/include

But it depends on your makefile.
