how to auto redirect to https from http

[Dave]

Hi,
  when user types http://www.mydomain.com, how to redirect to secure url 
https://www.mydomain.com?  I know that a servlet filter can do that. Is there 
an easier way?
   
  In server.xml,  redirectPort="8443" for port 80, it did not work as I 
expected.
   
       <Connector port="80" address="${jboss.bind.address}"
         maxThreads="250" strategy="ms" maxHttpHeaderSize="8192"
         emptySessionPath="true"
         enableLookups="false" redirectPort="8443" acceptCount="100"
         connectionTimeout="20000" disableUploadTimeout="true"/>
      
        <Connector port="8443" address="${jboss.bind.address}"
           maxThreads="100" strategy="ms" maxHttpHeaderSize="8192"
           emptySessionPath="true"
           scheme="https" secure="true" clientAuth="false"
           keystoreFile="${jboss.server.home.dir}/keystore"
           keystorePass="123456" sslProtocol = "TLS" />

  Thanks for help.
