Java EE (Java Enterprise Edition) General Discussion

Hello,
I am actually working on a JSF web application. We use JSF 2.1.2 and primefaces 2.2.1.
Actually we have some memory Problems on the server. So we made some tests with STATE_SAVING_METHOD "client"
and STATE_SAVING_METHOD "server" and com.sun.faces.serializeserverstate.

My question here is, where does JSF write the server state on disk (directory, filename).
Is it possible to change this manually?? (We need this, for daily clean up)

What happens if the memory on harddisk is full? JSF will change mode or just stop??

When will JSF clean up the serialized server states?

Is JSF compressing the serverstate before serializing or does JSF compress only for "client"-method??

I have searched the net but was not able to find any satisfying information.
I hope anybody can help me!

thx
