java - How to write UTF-8 symbols in JSP with Struts 2

Question

I have a list in my action which I field by values saved on a MySql DB.

I only have one object stored, which has designation €.

In JSP when I do this:

<s:iterator value="unitesList">
    <s:property value="designation"/>
</s:iterator>
<s:select list="unitesList" name="unity" listValue="designation" listKey="id" />

I have this:

€
<select name="unity" id="unity">
    <option value="1">?</option>
</select>

Why on <s:select> element the € element is transformed in a ? ?

Answer 1

Place this on the top of the JSP page. Symbols in UTF-8 encoding displays better than ?.

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