problem with encoding

nevermoreagain May 22, 2007 1:38 AM

Hello..
i'm new to seam =)
i use Seam-gen to generate a simple Seam project.. But there is a problem..
When i do search in MySQL database it works fine with data written in english but every time i do search some text written in my native language it's not working. This data even shown correctly in this Seam project but every time i push search button, text in <h:inputText> became unreadable.
In Seam Reference i found that i should put this in components.xml

<web:character-encoding-filter encoding="UTF-8"
override-client="true"
url-pattern="*.seam"/>

but this doesn't change anything. Does anyone know how to solve this problem ?

thank you for your aswers =)

There's a few layers this can fail at. You are right that you need the character encoding filter.

Do you know if the data is being stored/inserted correctly at the DB level? (ie- connect to MySQL using some other tool to see). MySQL allows you to specify the character encoding at a DB-wide level or on a per-table level.

When I create tables manually I always specify "DEFAULT CHARACTER SET UTF8;" explicitly, in the name of paranoia, but you can also use "default-character-set=utf8" in the my.ini config file. This is handy if seam-gen is generating your schema for you, which I guess is probably the case.

If everything is OK at the DB level, then I'm not sure..

Well, i guess the problem is that pages generated as facelets(xhtml)..

To set charset/encoding in JSP we can use
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>

so i'm wondering is there anything like this to use in facelets

My root facelets template just has the direct meta HTML tag in it:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

The Seam blog example uses an f:view in its template.xhtml but specifies the encoding in a direct meta tag. I didn't even think f:view had such a parameter?

I don't even use f:view, as I never saw it in the facelets developer documentation: https://facelets.dev.java.net/nonav/docs/dev/docbook.html#gettingstarted-view-template

yeahh

These is one of those things you learn because someone told you sometime :)

I saw this because I have just migrate my code to seam-cvs and Jboss 4.2. There, the default is contentType=xml/xhtml which turned all my javascipts as illegal things .. weird huhhhh ?

So, I got this tip on this forum in the "seam cvs examples on jboss 4.2"... I could not find any reference to it... and do not worry about seam doc.. this is from jsf implementation.

and my javascripts was not working w/ just this:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

...

for sure.. they just start working again when I added contentType on f:view

take a look bellow. This working for me.

AFAIK, you need it in both the meta tag and the f:view. At least I think that's what Jacob told me. I guess Facelets uses a special UIViewRoot or something.

I'm not sure if the Seam examples have it completely correct.

You would be better off asking about this stuff in the facelets forums, and checking their FAQ.
