Using JNative call dll

Reference from JNative Howto

JNative is simpler than JNI.

1.Copy JNativeCpp.dll to Windows/systems32 folder.
2.Copy JNative.jar to your java project lib folder.
3.The example code to call dll function:

package jnative;

import java.sql.Timestamp;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.xvolks.jnative.JNative;
import org.xvolks.jnative.exceptions.NativeException;
import org.xvolks.jnative.Type;

public class OMSignAPI {

    public static final String DLL_NAME = "C:\\Program Files\\OrderMaster\\OMSignAPI.dll";
    private static JNative api;

    public static void main(String[] args) {
        DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd kk:mm:ss");
        Timestamp now = new Timestamp(new Date().getTime());
        
        try {
            GoOrder("MTX001","",dateFormat.format(now).toString(),1,7400);
        } catch (NativeException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    public static final void IniDllAndPosition(String signID,
            int iniPosition) throws NativeException, IllegalAccessException {
        api = new JNative(DLL_NAME, "IniDllAndPosition");
        api.setRetVal(Type.INT);
        int i = 0;
        api.setParameter(i++, Type.STRING, signID);
        api.setParameter(i++, Type.INT, "" + iniPosition);
        api.invoke();
        int a = Integer.parseInt(api.getRetVal());
        if (a == 0){
            System.out.println("OMSignAPI IniDllAndPosition Error!!");
        }
    }

    public static final void GoOrder(String signID, String bySignStr,
            String dateTimeStr, int nowPosition, double nowPrice)
            throws NativeException, IllegalAccessException {
        api = new JNative(DLL_NAME, "GoOrder");
        api.setRetVal(Type.INT);
        int i = 0;
        api.setParameter(i++, Type.STRING, signID);
        api.setParameter(i++, Type.STRING, bySignStr);
        api.setParameter(i++, Type.STRING, dateTimeStr);
        api.setParameter(i++, Type.INT, "" + nowPosition);
        api.setParameter(i++, Type.DOUBLE, "" + nowPrice + ".0");
        api.invoke();
        int a = Integer.parseInt(api.getRetVal());
        if (a == 0){
            System.out.println("OMSignAPI GoOrder Error!!");
        }
    }
}
