Body
I have a servlet which receive some parameter from the client ,then do some job. And the parameter from the client is Chinese,so I often got some invalid characters in the servet. For exmaple: If I enter <pre><code>http://localhost:8080/Servlet?q=中文&type=test </code></pre> Then in the servlet,the parameter of 'type' is correct(test),however the parameter of 'q' is not correctly encoding,they become invalid characters that can not parsed. However if I enter the adderss bar again,the url will changed to : <pre><code>http://localhost:8080/Servlet?q=%D6%D0%CE%C4&type=test </code></pre> Now my servlet will get the right parameter of 'q'. <h2>What is the problem?</h2> <code>UPDATE</code> BTW,it words well when I send the form with post. WHen I send them in the ajax,for example: <pre><code>url="http://..q='中文', xmlhttp.open("POST",url,true); </code></pre> Then the server side also get the invalid characters. It seems that just when the Chinese character are encoded like %xx,the server side can get the right result. That's to say <code>http://.../q=中文</code> does not work, <code>http://.../q=%D6%D0%CE%C4</code> work. But why "<code>http://www.google.com.hk/search?hl=zh-CN&newwindow=1&safe=strict&q=%E4%B8%AD%E6%96%87&btnG=Google+%E6%90%9C%E7%B4%A2&aq=f&aqi=&aql=&oq=&gs_rfai=</code>" work？ <img src="https://i.stack.imgur.com/PKkIw.jpg" alt="alt text">

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.
