Oliver Heger commented on CONFIGURATION-203:
--------------------------------------------

Serializing a Configuration only to make it persistent certainly does not make 
much sense. But the other use cases listed in this ticket seem valid to me.

Consider a web application that creates a Configuration with settings for a 
user on log in. This Configuration should be stored in the Session, so it 
should be serializable. It may also be used as a parameter of a call to a 
remote EJB, which also requires it to be serializable.

But as I said, I don't believe that we can make concrete Configuration 
implementations themselves serializable, only the pure data they contain. In 
the case of combined configurations that would mean creating a serializable 
data object containing the data of all child configurations involved.

Anyway, I agree that this issue will probably not be addressed in the 1.x 
series. So I am going to change the fix version.

> It would be nice if org.apache.commons.configuration.Configuration extended 
> java.io.Serializable and its implementations were serializable as well.  
> Theoretically, most configurations are constructed from "serialized" data 
> sources.
