I am trying to call a C++ function from a java class.
The java class compiles and I also get the header file when I run javah on the class but when I try running the app, its throwing exceptions.
Here is my java code below, the c++ class is a working piece of code.
Please let me know what I might be doing wrong here.

The C++ function I am trying to call is :

VerifyID(BSTR CalcID, BSTR PublicKey, short *rc)

Java class:

public class certify {



static {

try {

System.loadLibrary("Certificate");

}

catch( UnsatisfiedLinkError x )

{

System.out.println("Error in static code");

}



}



certify() {

try {

cplusPtr = initCplusSide();

}

catch( UnsatisfiedLinkError x )

{

System.out.println("Error in certify constructor");

}



}


public native short VerifyId(int cplusPtr, String calcId, String publicKey);




private native int initCplusSide();



private int cplusPtr;


public static void main (String [] args) {



String calcId = "123";

String publicKey = "123456";



short retCode = 0;



try {



certify cert = new certify();



retCode = cert.VerifyId(cert.cplusPtr, calcId, publicKey);



System.out.println("retCode is: "+retCode);

}

catch( UnsatisfiedLinkError x )

{

System.out.println("Error in certify main");

}


}

}
