some googling says that i need to implements Serializable all class that i used in this function.but i've already done that.and this error seems quite general,i cant quite figure this out.and dont really understand error below

    org.apache.derby.client.am.PreparedStatement40

The clue is here:

StateManagerImpl.writeState

It is likely that you have set an inappropriate value on one of your components. You probably need to use EL binding in a place where you have explicitly called setValue in a backing bean (my best guess based on the information posted).

JSF uses stateful UI component trees that are persisted between requests. The tree structure and any value set on the tree is saved at the end of the Render Response phase. Typically, data is saved either in the session or in a hidden form field. Therefore, any value set on a component must be serializable.

Looks like you're storing a (JDBC) PreparedStatement in one of your objects that is getting serialized (probably part of a session). You should move it somewhere else or mark it transient (don't forget it will be missing when it gets restored).

The problem is that the object you are trying to serialize has a reference to org.apache.derby.client.am.PreparedStatement40, or most probably, to a java.sql.Statement, which is the interface that class implements. You have to remove that reference to make it work
