How To Install Apache Tomcat on Ubuntu

Application servers may have different settings for character encodings. We strongly recommend UTF-8 where possible.

By default, Tomcat uses ISO-8859-1 character encoding when decoding URLs received from a browser. This can cause problems when Confluence's encoding is UTF-8, and you are using international characters in the names of attachments or pages.

To configure the URL encoding in Tomcat:

Step 1 - Configure connector:

1. Edit conf/server.xml and find the line where the Coyote HTTP Connector is defined. It will look something like this, possibly with more parameters:
   

   <Connector port="8080"/>

2. Add a URIEncoding="UTF-8"property to the connector:
   

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

3. If you are using mod_jk you should apply the same URIEncoding parameter as above to the AJP connector if you are using mod_jk, and add the following option to your Apache mod_jk configuration:

<Connector port="8009" protocol="AJP/1.3" URIEncoding="UTF-8"/>

Step 2 - Add Encoding Filter:

The following filter settings need to be added  in  “web.xml” of {Tomcat_DIR}/conf folder:
  <!-- A filter that sets character encoding that is used to decode -->
  <!-- parameters in a POST request →

    <filter>
        <filter-name>setCharacterEncodingFilter</filter-name>
        <filter-class>org.apache.catalina.filters.SetCharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <async-supported>true</async-supported>
    </filter>
   <filter>
      <filter-name>Set Character Encoding</filter-name>
      <filter-class>com.matrixone.servlet.SetCharacterEncodingFilter</filter-class>
      <init-param>
         <param-name>encoding</param-name>
         <param-value>UTF-8</param-value>
      </init-param>
   </filter>

    <filter-mapping>
        <filter-name>setCharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

Step 3 - Restart Tomcat.
