Thanks for your response. But that is what I did for the class "com.demo.helloblaze.dto.ContactDTO " I registered the root package as follows <class name="com.demo.helloblaze.dto.*"/>
<allow-classes> <class name="flex.messaging.messages.*"/> <class name="flex.messaging.io.*"/> <class name="flex.messaging.io.amf.*"/> <class name="com.demo.helloblaze.dto.*"/> </allow-classes> I still get the same error whether or not ContactDTO implements Serializable interface.
