Tomcat Configuration Gotchas

Request Garbling (Encoding)

Add URIEncoding="UTF-8" in conf/server.xml:

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000"
           redirectPort="8443" URIEncoding="UTF-8" />

By default Tomcat uses ISO-8859-1 for request/response encoding. See the official docs for more details.
