Question

If I need to set the same encoding for all applications deployed in a tomcat instance, I can edit server.xml and add a section like this:

<Connector port="8081" protocol="HTTP/1.1" 
   connectionTimeout="20000" 
   redirectPort="8443" 
   URIEncoding="UTF-8"/>

Is there a way to specify encoding for a certain application? (maybe in its web.xml or somewhere else)?

As far as I know web.xml does not allow what you want, so I’d suggest the following ways.

1. set it per page (e.g. for JSP <%@page pageEncoding="UTF-8" %>)
2. Use HTTP filter to set encoding. In this case you do not have to set it for each page separately.
3. If you are using web framework try to use tools it provides. For example for Struts you can define encoding in template definition.
