Serializer/DeSerializer question/Help

["Tolsch, Ed" <Ed...@fmr.com>]

I'm trying to use "my own" (Castor from Exolab) serializer / deserialer to
marhsall/unmarshall my xml to/from Java Beans. 
 
My deploy.wsdd file looks like the following:
  <service name="WebSvcsImpl" provider="java:RPC">
 
      <parameter name="className" value="com.fmr.fesco.hw.WebSvcsImpl"/>
      <parameter name="allowedMethods" value="PingTest"/>
      <parameter name="scope" value="Request"/>
 
      <typeMapping
        xmlns:ns=" http://fmr.com/hw/ <http://fmr.com/hw/> "
        qname="ns:FESCOHead"
        type="java:com.fmr.fesco.hw.fmrutil.FESCOHead"
        serializer="com.fmr.fesco.hw.router.utils.CastorSerializer"
        deserializer="com.fmr.fesco.hw.router.utils.CastorSerializer"
        encodingStyle=" http://schemas.xmlsoap.org/soap/encoding/
<http://schemas.xmlsoap.org/soap/encoding/> "
      />

Yet I get the following Class Cast Exception.  Can anyone provide any
insight?  This is what I had done successfully in SOAP 2.2. Thanks in
advance.
