Struts, UTF-8 and form submissions

February 23rd, 2006 by ian.purton

Struts will convert data that is received from form submissions to a default encoding because most browsers don’t set the content type.

To stop struts mangling the data you need to set the content type with a filter before it gets as far as the struts layer.

Use the filter below

You’ll need to add these settings to your web.xml

Be careful how you view the output of any form submissions, for instance the console on eclipse is not UTF-8 by default.

In my case I have to show Japanese character on the page and to be saved into database. I've tried with filter but it doesn't work out although it's going to filter class but the charachter are still in ?? format. Could someone help me? Thanks in advance.

Thanks for this post. In my case, I also had to set response.setCharacterEncoding("UTF-8"); to get everything to work. Adding the filter class and the directives in web.xml is simple.

Your tip only works if coupled with a Tomcat connectors modification :
I was obliged to add these attributes in order to get full (and effective) UTF-8 encoding :

URIEncoding="UTF-8" useBodyEncodingForURI="true"

NOTE : it may help jy ...

I know this solution and have ever improved it on one of my applications.
But on another application, I have used the same solution but it doesn't work :
my filter is the first declared in my web.xml, but the code line : request.setCharacterEncoding(â€ISO-8859-15â€³); seems to not work.
any idea to help me ?

For who it is in the development of the first project and finds a solution so practical. It is very good. Easy to implement, fantastic. Congratulations. Thank you.

Sorry it should be :

From : request.setCharacterEncoding(â€UTF8â€³);
To: request.setCharacterEncoding(â€UTF-8â€³);

Rajesh

Shouldnt the necoding be UTF-8 instead of UTF8.

From : request.setCharacterEncoding("UTF8");
To: request.setCharacterEncoding("UT-F8");
