Java – JSP / GlassFish: how to correctly set UTF-8 encoding

I'm looking for help to convert all layers in the stack to UTF - 8 encoding

I found this good article:

http://www.javapractices.com/topic/TopicAction.do?Id=206

Describe three areas where I need to worry about coding Since my (1) Oracle database is currently set to UTF-8, I need to worry about (2) browser and (3) server

I also found this detailed article

http://balusc.blogspot.com/2009/05/unicode-how-to-get-characters-right.html#JSPServletRequest

I'm trying to follow the following, but there are some novice questions about implementation

To solve the browser problem, I ensure that the following is included at the top of each JSP page:

<%@page pageEncoding="UTF-8"%>

(for reference, see here)

To solve the server problem, I make sure to issue a request Getparameter () or request Before the getattribute () statement, include the following lines in the java servlet and JSP pages:

request.setCharacterEncoding("UTF-8");

Because I use GlassFish 3.1 2. I know it does not use UTF - 8 by default, so I need to set it manually in some way

I've seen many websites talking about a website called GlassFish web XML file Is this part of an ordinary GlassFish? I don't know where to find it I've been using web. Inf in the web - inf folder XML file as my web application Someone can help me find out if I need to modify this web XML file, or do I need to find or create a file called GlassFish web XML to configure the encoding of GlassFish?

My web XML file to:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems,Inc.//DTD Web Application 2.3//EN" 
    "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app> 
...

For JSP / servlet requests, I'm on the web The XML file contains the following lines

<parameter-encoding default-charset="UTF-8"/>

Can be put into the web XML file? Or, does it need to go into some GlassFish web XML file?

For JSP / servlet responses, I put the following in my web XML file (see the accepted answer here):

I assume that these lines are just inserted between < web app > and < / web app > But let me know if they should enter other descriptors (such as < GlassFish web app > and < / GlassFish web app >)?

I also added the following content to JSP < head > part:

<Meta http-equiv="content-type" content="text/html; charset=utf-8">

Solution

glassfish-web. XML is a file that you can create in the web - inf folder For GlassFish 3 x. It must be similar:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app>
    <jsp-config>
    </jsp-config>
    <parameter-encoding default-charset="UTF-8" />
</glassfish-web-app>

You are right. The parameter encoding settings must be in this file, not in the web xml
