Hi-

I've successfully execute the JNI examples, and have a nice hello world
program that uses JNI.  However, the test examples use the default
package.  When I try to move my code to another package, I get
unsatisfied link errors.

Here's the sitch:

I have a package, test.jni that contains JNITest.java.  There is a
native method in it called helloWorld() that I attempt to call.  To
build the shared object, I did the following:

javah -jni test/jni/JNITest

in the directory I ran the command from I get:
test_0002fjni_0002fJNITest.h

My c file, the originally named jnitest.c is in the same directory.

I compile it all together via:
gcc -shared -olibblah.so -static -lc jnitest.c
-I/usr/java/j2sdk1.4.2_05/include/ -I
/usr/java/j2sdk1.4.2_05/include/linux/

The result is I get libblah.so

libblah.so contains helloWorld:

[root@localhost JNI Test]# nm libblah.so |head -3
00000700 T Java_test_0002fjni_0002fJNITest_helloWorld
000017e8 A _DYNAMIC
000017bc A _GLOBAL_OFFSET_TABLE_

I compile my java file with:
[root@localhost JNI Test]# javac test/jni/JNITest.java

I get no errors or warnings.

I then attempt to run it:

[root@localhost JNI Test]# java test/jni/JNITest
Exception in thread "main" java.lang.UnsatisfiedLinkError: helloWorld
       at test.jni.JNITest.helloWorld(Native Method)
       at test.jni.JNITest.main(JNITest.java:15)

This works just fine if I have things in the default package.  Moving
it to another package, regardless of how I build this thing fail with
the above.

My JNITest.java is below ( and below that, jnitest.c ).  Any ideas?
All the examples seem to be in the default package, so I figure I am
probably doing something stupid.

package test.jni;

public class JNITest
{
 static {
   System.loadLibrary( "blah" );
 }

 public native void helloWorld();

 public static void main ( String[] args )
 {
     JNITest test = new JNITest();
     test.helloWorld();
 }
}

// end
jnitest.c:
#include <stdio.h>
#include "test_0002fjni_0002fJNITest.h"

JNIEXPORT void JNICALL Java_test_0002fjni_0002fJNITest_helloWorld
(JNIEnv * env, jobject obj)
{
 printf ( "Hello world\n" );
}
