Class ObjectSerializer
java.lang.Object
org.apache.tomcat.util.ObjectSerializer
- public final class ObjectSerializer
- extends java.lang.Object
Helper for object reloading. Will change the classloader of a
serializable object.
The object must be serializable - the caller should do special
actions for all non-serializable objects ( like using their
specific protocol ).
Old comment: ( code works now for any object, not only HttpSession )
This class manages the serialization of HttpSession object across
classloader reloads. It does this by first getting a copy of the
HttpSessions hashtable from the SessionManager and then using a
special internal class ObjectInputStream that uses the newly created
classloader to de-serialize the sessions. This class is called from
within the Handler.handleReload() method. Much of this code
is essentially the same as what I put into the Apache JServ release
so it is pretty well tested. It also depends on having HttpSession
implement the read/writeObject methods properly to only accept
objects that are serializable.
