Kinda lost with your question(s), BUT - If you want to know about different states of the stateful session bean lifecycle, then "Mastering EJB" by Ed Roman is your best resource.

A transient instance variable in SFSB can be declared as follows:
In this case the state of wouldn't be wirtten to disk if the SFSB is poing to be passivated. Only serializable variables can be passivated (written to disk). All basic Java types (int, short, boolean) and all custom classes that implement the marker interface
