Java调用第三方dll文件的使用方法

public class OtherAdapter {
static
    { 
        //System.loadLibrary("Connector");//载入需要调用的dll  Connector.dll
		System.load("d://Connector.dll");//载入dll  Connector.dll
    }

    //用native关键字修饰将被其它语言实现的方法
	//dll文件中对应的函数声明
   	public native static int _PWLogon(String lpszDS,String lpszUser,String lpszPWD);
	//函数声明
   	public native static void _PWLogout();
	public native static String _GetPWLastError();
	public native static String _GetPWFolders(long lParentFolderno);
	public native static String _GetPWDocuments(long lFolderno);
	public native static String _GetPWFiles(long lFolderno,long lDocno);
		
   //public native static String pirntStr(String msg);//函数声明
   public static void main(String[] args){
        //本地方法的调用
        int rs=_PWLogon("服务器","账号","密码");
        System.out.println("用户登录状态："+rs);
				if(rs==1)
				{
					System.out.println("获取顶级目录："+_GetPWFolders(0));
					
					System.out.println("获取父子目录："+_GetPWDocuments(54));
					
					System.out.println("下载指定文件："+_GetPWFiles(54,2));
					
					_PWLogout();
				}
				else
				{
					System.out.println("获取错误信息："+_GetPWLastError());
				}
    }
}
