Jni.h no such file or dir ??? What am I doing wrong ??

Question

Hello I am following the jni tut and I am at the last part and when I go to compile the .c file I get this error no such file or dir <jni.h>.How can I get the jni.h file?

Answer 1

First let me say thank you GumB for your time.Ok now this is everything I have done
1)I have made a java file and comepiled it
2)I used the javah -jni HelloWorld to make a .h file
3)I have made the .c file which is posted here
Ok now my header file and my .class file and the .c file are all in the dir /home/dwa/JavaP
when I cd /home/dwa/JavaP into my dir and try to use this to compile
gcc -I/usr/java/j2sdk1.4.0_02/include -I/usr/java/j2sdk1.4.0_02/include/linux \ HelloWorldImp.c -o libhello.so
I get the errors
HelloWorldImp.c No such file or directory the file is there in /home/dwa/JavaP
gcc : No input file
The HelloWorld.c file is there in /home/dwa/JavaP
and for the sec error No iput file
I thought this what the input files
-I/usr/java/j2sdk1.4.0_02/include -I/usr/java/j2sdk1.4.0_02/include/linux
any clues ? Also like I said I can compile a reg .c program with know prob in the same dir as well, also this is the .c file now
#include <jni.h>
#include "HelloWorld.h"
#include <stdio.h>
JNIEXPORT void JNICALL
Java_HelloWorld_displayHelloWorld(JNIEnv *env, jobject obj)
printf("Hello world!\n");
return;
Thank for your time
Sincerely
