新人学习JSP和SERVELT



    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 HelloWorldSerlet extends HttpServlet{



        protected void doGet(HttpServletRequest req, HttpServletResponse resp)

                throws ServletException, IOException {

            PrintWriter out = resp.getWriter();

            String str = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">";

            out.print(str + "<HTML><head><title>example</title></head><body>Hello World Test!!!</body><HTML>");

        }

    }

按照标准来。


response.setContentType("text/html");//注意这个
		PrintWriter out = response.getWriter();
		out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
		out.println("<HTML>");
		out.println("  <HEAD><TITLE>A Servlet</TITLE></HEAD>");
		out.println("  <BODY>");
		out.print("    This is ");
		out.print(this.getClass());
		out.println(", using the GET method");
		out.println("  </BODY>");
		out.println("</HTML>");
		out.flush();
		out.close();

response.setContentType("text/html"); 或者 setContentType("text/html;charset=GB2312"); 请参看servlet html头信息

  req.setCharacterEncoding("GBK");
        PrintWriter out=resp.getWriter();
        out.println("<html>");
        out.println("<head>");
        out.println("<title>xxx</title>");
        out.println("</head>");
        out.println("<body>");
        out.println("<h2>xxxxxxxxx---</h2>");
        out.println("</body>");
        out.println("</html>");
        out.close();//关闭输出对象
