contex.xml

Kod Izaberi


<?xml version="1.0" encoding="UTF-8"?>
<Context reloadable="true">
	<Resource name="jdbc/mysql" auth="Container" type="javax.sql.DataSource"
		driverClassName="com.mysql.jdbc.Driver"
		url="jdbc:mysql://localhost:3306/xxxx?useUnicode=true&amp;characterEncoding=utf8&amp;charactetrResultSets=utf8"
		username="xxxx" password="xxxx" maxActive="20" maxIdle="10"
		maxWait="-1" />
</Context>

Ukoliko koristite neki vas DB manager potrebano je na database url dopisati:

Kod Izaberi


jdbc:mysql://localhost:3306/cirilica?useUnicode=true&characterEncoding=utf8&charactetrResultSets=utf8

Na jsp strani podesiti:

Kod Izaberi


<%@ page language="java" contentType="text/html; charset=UTF-8" 	pageEncoding="UTF-8"%>

Ukoliko koristite servlet kao kontroler potreno je da parametre primate na sledeci nacin:

Kod Izaberi


String name = new String(request.getParameter("name").getBytes("ISO-8859-1"), "UTF-8");

index.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
