Re: problem with distribuited events

Hello,

I'm using Java 1.6.
I'm using a locale JavaSpaces space.

If I don't export the object using UnicastRemoteObject.exportObject() fro=
m
the constructor or from the caller the next exception is thrown:


java.rmi.MarshalException: error marshalling arguments; nested exception =
is:=20
=09java.io.NotSerializableException: main.Listener

I've tried implementing Serializable in Listener class, still not exporti=
ng
the listener. In this case the following exception is thrown:

I've attached the full src directory of the project. If you can , take a
look, or even try it, maybe it's a problem with my space.

Thank you very much for your answers.
