    <p>I have a problem in my Java webapp.</p> <p>Here is the code in index.jsp:</p> <pre><code>&lt;%@page contentType="text/html" pageEncoding="UTF-8" %&gt; &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt; &lt;% request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8"); %&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"&gt; &lt;title&gt;JSP Page&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;h1&gt;Hello World!&lt;/h1&gt; &lt;form action="index.jsp" method="get"&gt; &lt;input type="text" name="q"/&gt; &lt;/form&gt; Res: &lt;%= request.getParameter("q") %&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>When I wireshark a request, my browser sends this header:</p> <pre><code>GET /kjd/index.jsp?q=%C3%A9 HTTP/1.1\r\n ... Accept-Charset: UTF-8,*\r\n </code></pre> <p>And the Tomcat server returns me this:</p> <pre><code>Content-Type: text/html;charset=UTF-8\r\n </code></pre> <p>But if I send "é"(%C3%A9 in UTF-8) in my form, "é" is displayed instead.</p> <p>What I understand is that the browser sends an "é" encoded with UTF-8 (the %C3%A9).</p> <p>But the server interpret this as ISO-8859-1. So the %C3 is decoded as à and %A9 as ©, and then sends back the response encoded in UTF-8.</p> <p>In the code, the requests should be decoded with UTF-8:</p> <pre><code>request.setCharacterEncoding("UTF-8"); </code></pre> <p>But, if I send this url:</p> <pre><code>http://localhost:8080/kjd/index.jsp?q=%E9 </code></pre> <p>the "%E9" is decocded with ISO-8859-1 and an "é" is displayed.</p> <p>Why isn't this working? Why requests are decoded with ISO-8859-1?</p> <p>I've tried it on Tomcat 6 and 7, and on Windows and Ubuntu.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
