Question

我的基于Web服务的应用程序出现词汇错误。如何解决这个问题？请帮帮我。

@WebMethod(operationName = "operation")
public String operation(@WebParam(name = "username") String username, @WebParam(name = "password") String password){ 

    String message = "";
    Connection myConObj = null;
    Statement myStatObj = null;
    PreparedStatement ps;  
    ResultSet myresObj = null;
    String query = "SELECT `USERNAME`, `PASSWORD` FROM HIRUNA.BANKLOGIN WHERE `USERNAME`=? AND `PASSWORD`=?";

    try{

        myConObj = mybank.getConnection();
        ps = myConObj.prepareStatement(query);
        ps.setString(1, username);
        ps.setString(2, password);
        ResultSet result = ps.executeQuery();

        result.next();
        message =  "Success!";
        result.close();
        myConObj.close();
        return message;

    }catch(SQLException ex){
        Logger.getLogger(login.class.getName()).log(Level.SEVERE, null, ex);
        return message;
    }

}

这是错误..

严重：java.sql.SQLSyntaxErrorException：第1行的词法错误，第8栏。遇到：＆＃34;`＆＃34; （96），之后：＆＃34;＆＃34;。
