When In Java load jni dll, JDK 1.8 UnsatisfiedLinkError

I load C++ JNI DLL on my Java project. It works quietly good on JDK 1.6 but there is a probelm JDK 1.8. Is there any change in C++ JNI DLL loading in Java 1.8?

I have attached errors and result below.

JDK 1.8 Console : 

Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\ws-pidion\PidionSDK\oojnidotnet.dll: Can't find dependent libraries
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1941)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1857)
at java.lang.Runtime.loadLibrary0(Runtime.java:870)
at java.lang.System.loadLibrary(System.java:1122)
at JavaCallNative.<clinit>(JavaCallNative.java:14)

Codes: 

File readReturnNativeStringVaueFile;

static {
    System.loadLibrary("oojnidotnet");
}

protected void finalize() throws Throwable {
    super.finalize();
}

public native boolean connect(String paramString);

Same codes work with JDK 1.6.

Thanks.

I solved this problem with user2543253s helping.

For JDK 1.8:

  • Need 2 DLL Lib (C:\Program Files (x86)\Java\jdk1.6.0_45\jre\bin\plugin2) (2 DLL libs copy to project path. )

    System.loadLibrary("msvcr71");
System.loadLibrary("npjp2");

System.loadLibrary("oojnidotnet");

It works this way in 1.8.

Thanks.
