1. About JSP to receive the garbled code of the FORM parameter:

<% @ page contenttype = "text / html; charset = GB2312"%> <%! Public string getstr (string str) {string temp_p = str; byte [] temp_t = temp_p.getbytes ("ISO8859-1"); string temp = new string (TEMP_T); Return Temp;} Catch (Exception E) {} return "null";}%>

2. About the servlet to receive garbled with the FORM parameter.

File name: Threeparams.java content is as follows: package moreeservlets;

Import java.io. *;

Import javax.servlet. *;

Import javax.servlet.http. *;

Public Class ThreeParams Extends Httpservlet

{

/ / Define a function getStr () to solve the problem of garbled code

Public string getstr (string str) {

Try {string temp_p = STR;

BYTE [] TEMP_T = Temp_p.getbytes ("ISO8859-1");

String temp = new string (temp_t);

Return Temp;

}

Catch (Exception E) {}

Return "NULL";

}

// - Receive three parameters from FORM and display. Note that the third parameter has no conversion, which can be used to compare.

Public void doget (httpservletRequest Request,

Response.setContentType ("text / html; charSet = GB2312");

PrintWriter out = response.getwriter ();

String DOCTYPE =
