The crash happened outside the java virtual machine in native code

I have a biometric device with which I am given some C++ dlls. I am trying to call methods inside these using java (jna). I am loading the dll "zkemsdk.dll+" as follows:

zkemkeeper INSTANCE1 = (zkemkeeper)Native.loadLibrary("zkemsdk", zkemkeeper.class);//zkemsdk is the dll, I am loading the dll here.

Then, I am calling the function:

zkemkeeper.INSTANCE1.Z_Connect_NETEX("ip address",4370);//Z_Connect_NETEX is a function inside zkemsdk.dll

This returns me true or false based on whether am connected to the biometric device or not.Thus I am able to invoke this method without issues. But for other methods inside the dll, run time exception is thrown in console:

Can someone help me resolve this issue. ??? Following is the content of the log file generated.
