loading more than one dll in the same project with jni

Question

I have project cli c++ that i need it in java so i'm using jni to access to these methods, and it's fine with a sample project that is have no dll references but when i include any other dll the jre crashed,

for more detail i have this example:

test is the first cli c++ project that is using dllNet and i use i in my java project:

test code:

using namespace dllNet;
JNIEXPORT jstring JNICALL Java_alquasar_aimetis_AimetisCallJNI_getAllCameras
(JNIEnv *env, jclass cls, jobject srv, jobject cams){
dllNet::Class1::SayHi();
return env->NewStringUTF( "Hello, World!" );
}

dllNet code:

using System;

namespace dllNet
{
    public class Class1
    {
        public static void SayHi()
        {
            System.Console.WriteLine("Hiiiiiiiiiiiiiiiiii .....");
        }
    }
}

java code:

public class AimetisCallJNI {

    static{
                System.load("C:/Users/alquasar/Desktop/mejdi/Aimetis/bin/dllNet.dll");
        System.load("C:/Users/alquasar/Desktop/mejdi/Aimetis/bin/test.dll");
    }
public static native String getAllCameras(ServerAis srv, CamerasAis list);
public static void main(String[] args) {
        ServerAis srv = new ServerAis("192.168.0.42", "admin", "admin");
        CamerasAis list = new CamerasAis();
new AimetisCallJNI().getAllCameras(srv, list);
}

and this is th error:

You can't, and you don't need to, load the C# DLL. You only need to load the DLL that contains your JNI code.
