I can't Send a class which implements Serializable to a Bean,if i send i got classnotfound exception and
MarshallingException, pls reply me soon.
When you pass an Object to the Bean(mean the EJB conatiner will recieve and use its value). For Its Work. the EJB container must instanciate that an object to get the value object that client pass to it. so this class must direct in your App server.
like How EJB work: how Client can call EJB: It need some hepler class from EJB: EJB Client.jar file. . . (eg: PK class of an Entity Bean must be in both CLient and AppServer
Hope this will help
