Set the charset in your .jsp page:

       <%@page contentType="text/html;charset=Shift_JIS"%>
       

Adjust your driver's URL

      <dbconnection
        id="edict"
		name   = "jdbc:mysql://localhost/edict?useUnicode=true&amp;characterEncoding=Shift_JIS"
		isJndi = "false"
		conClass  = "org.gjt.mm.mysql.Driver"
		username = "whoever"
		password  = "whatever"
	/>
      

Note: to use UTF-8 with MYSQL, you need to use:

      jdbc:mysql://localhost/edict?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&mysqlEncoding=utf8
      

Add a filter to web.xml

      <filter>
 
         <filter-name>Set Character Encoding</filter-name>
 
         <filter-class>org.dbforms.util.external.SetCharacterEncodingFilter</filter-class>
 
         <init-param>
 
            <param-name>encoding</param-name>
 
            <param-value>Shift_JIS</param-value>
 
         </init-param>
 
      </filter>
      
      
 
      <filter-mapping>
 
         <filter-name>Set Character Encoding</filter-name>
 
         <url-pattern>/*</url-pattern>
 
      </filter-mapping>
