Question

我有以下java代码：

import java.sql.Connection;   
import java.sql.DriverManager;   
import java.sql.ResultSet;   
import java.sql.Statement;


public class License {   
    public static void main(String[] args) {   

        Connection connection = null;   
        ResultSet resultSet = null;   
        Statement statement = null;   

        try {   
            Class.forName("org.sqlite.JDBC");   
            connection = DriverManager.getConnection("jdbc:sqlite:C:/license_tracker/usage.db3");   
            statement = connection.createStatement(); 
            System.out.println("Connection Successful!!!!");
            String query = "SELECT  USR.id,USR.name, ST.license FROM users USR, status ST, upd_ate UD WHERE UD.upt_id = (select max(p2.upt_id) from upd_ate p2) AND ST.id = USR.id AND ST.upt_id = UD.upt_id ORDER BY ST.license,USR.name";

            resultSet = statement.executeQuery(query);  

            while (resultSet.next()) { 

                System.out.printf("%8s   %-50s   %-7s%n",resultSet.getString("cymer_id"), resultSet.getString("name"), resultSet.getString("license"));   

            }   
        } catch (Exception e) {   
            e.printStackTrace();   
        } finally {   
            try {   
                resultSet.close();   
                statement.close();   
                connection.close();   
            } catch (Exception e) {   
                e.printStackTrace();   
            }   
        }   
    }   
}

我想以表格格式在Web浏览器中显示resultSet的内容，本质上是IE9。我已经搜索了这个，我认为有两种选择，使用JAVA applet或JSP。既然我必须在服务器上运行代码，那么我应该使用JSP吗？我对JSP并不熟悉，所以如果有人可以帮助我，我将不胜感激。我正在使用Eclipse Indigo＆amp;有Tomcat ver 7。

我在网页布局上有一个HTML代码。我想把信息放在桌子上。

Answer 2

也许你可以这样做：

import java.io.*;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class LicenseServlet extends HttpServlet {

public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
        PrintWriter out = response.getWriter();

        out.print("<html><body><table>");

        // ... pseudocode
        while (resultSet.next()) { 
            out.print("<tr><td>");
            out.print("%8s   %-50s   %-7s%n",resultSet.getString("cymer_id"), resultSet.getString("name"), resultSet.getString("license"));   
            out.print("</td></tr>");

        } 


        out.print("</table></body></html>");
  }
}
