Java Programming

hello every one. I want to use a DLL in mi project.To reach this aim i had started to use Java Native Access..

This is a desctiption of one of the most functions in my DLL:

long TRANS2QUIK_CONNECT (LPCSTR lpcstrConnectionParamsString, long* pnExtendedErrorCode, LPSTR lpstrErrorMessage, DWORD dwErrorMessageSize)

Where
lpcstrConnectionParamsString-string
pnExtendedErrorCode-pointer on a variable LONG
lpstrErrorMessage-pointer on a string
dwErrorMessageSize-long..

I tried to use this code for connect , but it isdo not work:

public interface TransToQuik  extends Library{

   public long TRANS2QUIK_CONNECT (String lpcstrConnectionParamsString, long pnExtendedErrorCode, String lpstrErrorMessage, long dwErrorMessageSize);


}

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    String Error;
    long len;
    long FunctionResult=0;
    long pnExtendedErrorCode=0;
    String lpstrErrorMessage="";
    long dwErrorMessageSize=0;
    TransToQuik lib = (TransToQuik) Native.loadLibrary ("D:\\java project\\Robot\\TRANS2QUIK.dll",TransToQuik.class);
    FunctionResult=lib.TRANS2QUIK_CONNECT("D:\\QUIK5.15\\info.exe",pnExtendedErrorCode,lpstrErrorMessage,dwErrorMessageSize);

    }

And this error occured

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: Error looking up function 'TRANS2QUIK_CONNECT': Íå íàéäåíà óêàçàííàÿ ïðîöåäóðà.
