Session Handler is missing in registry.

[PILLAI,RANJITH (HP-PaloAlto,ex1)]

  Hi there,

 Could anybody explain me why I am getting this exception when I am using my
own handler instead of SimpleSessionHandler though I have put handler name
and type in deploy.wsdd.

 http://xml.apache.org/axis/}stackTrace: org.apache.axis.ConfigurationEx
ception: Can't find handler name:'null' type:'SessionHandler' in the
registry
org.apache.axis.ConfigurationException: Can't find handler name:'null'
type:'SessionHandler' in the registry.

Thanks,
Ran
