        out.print("<html><head></head><body>hello world ~~mars</body></html>");
        out.close();
    }

/* protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        PrintWriter out = resp.getWriter();
        out.print("<html><head></head><body>hello world ~~mars</body></html>");
        out.close();
    }*/

}
package com.mars;

import java.io.IOException;
import java.io.PrintWriter;

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

public class ServletTest extends HttpServlet {

protected void doGet(HttpServletRequest req, HttpServletResponse resp)
   throws ServletException, IOException {
  PrintWriter out = resp.getWriter();
  out.print("<html><head></head><body>hello world ~~mars</body></html>");
  out.close();
}

/* protected void doPost(HttpServletRequest req, HttpServletResponse resp)
   throws ServletException, IOException {
  PrintWriter out = resp.getWriter();
  out.print("<html><head></head><body>hello world ~~mars</body></html>");
  out.close();
}*/

}

要求：

（1）编写JSP页面，创建表单，表单中包含“文本框”及“提交”按钮

（2）编写servlet程序，在程序中读取出用户在表单中输入的内容，并将其显示在页面上

（3）创建servlet 程序时，可采用MyEclipse中直接new—servlet的方式

package com.mars;

import java.io.IOException;
import java.io.PrintWriter;

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

public class ServletTest2 extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        response.setContentType("text/html;charset=gbk");
