[SOLVED] JNI gives Error undefined Symbol, do I miss an Headerfile?

[hannehomuth]

Hello Everyone,
at first thank you for reading this post. I'd like to you use the gnome keyring manager to save/load Passwords out of my own java app. If tried things with dbus, but it seems not to work. Now I wanna to write my own wapper for the method calls to use the keyring manager. I started to write my Java class. It looks like this.

Code:

/**
 *
 * @author jhomuth
 */
public class KeyRingConnector {
    
    public native void addPasswordToKeyRingManger();
    public native boolean isKeyRingDaemonAvailable();
    
    static
    {
       Runtime.getRuntime().load("/usr/lib/libdbus-1.so.3");
       Runtime.getRuntime().load("/usr/lib/libglib-2.0.so.0");
       Runtime.getRuntime().load("/lib/i686/cmov/libc.so.6");
       Runtime.getRuntime().load("/usr/lib/libpcre.so.3");
       Runtime.getRuntime().load("/lib/libselinux.so.1");
       Runtime.getRuntime().load("/lib/ld-linux.so.2");
       Runtime.getRuntime().load("/usr/lib/libgnome-keyring.so");
       Runtime.getRuntime().load("/home/jhomuth/projekte/LDAP/src/de/sourcepark/ldap/KeyRingConnector.dll");
    }    
}

Furthermore I wrote the C Class which looks like this

Code:

//File: KeyRingConnector.c
#include "de_sourcepark_ldap_KeyRingConnector.h"
#include <jni.h>
#include <stdio.h>
#include <stdlib.h>
#include <glib.h>
#include <gnome-keyring.h>
 
JNIEXPORT void JNICALL Java_de_sourcepark_ldap_KeyRingConnector_addPasswordToKeyRingManger (JNIEnv *env, jobject obj)
{
    printf("Damm I used JNI");
}
 
JNIEXPORT jboolean JNICALL Java_de_sourcepark_ldap_KeyRingConnector_isKeyRingDaemonAvailable (JNIEnv *env, jobject obj)
{
 
#define false 0
#define true (!false)
 
   if(gnome_keyring_is_available())
   {
        return true;
   }
   else return false;
}

But when I wanna run my Programm I get an java.lang.UnsatisfiedLinkError

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: /home/jhomuth/projekte/LDAP/src/de/sourcepark/ldap/KeyRingConnector.dll: /home/jhomuth/projekte/LDAP/src/de/sourcepark/ldap/KeyRingConnector.dll: undefined symbol: gnome_keyring_is_available

I think I'm missing a Headerfile in my C Class or do I have to load another library?

Thx for help

I found it by myself. I've had to put the libgnome-keyring into my own dll using

gcc -shared -o KeyRingConnector.dll KeyRingConnector.o /usr/lib/libgnome-keyring.so
