title: jsf application in tomcat cluster with session replication
body: <p>We have a jsf2 application in a tomcat clustering environment with session replication via SimpleTcp.</p>
  
  <p>When the balancer (mod_jk) changes the node we have an typical viewExpiredException.</p>
  
  <p>It seems not properly serialized jsf view state... any configuration suggestions?</p>
  
  <p>Thanks!</p>
  
  <p>Jose.</p>
