Hi,
Is it required that java bean used in a JSP implement Serializable interface.
No is my answer
http://www.onjava.com/pub/a/onjava/2003/06/11/jsp_progressbars.html
But the above link has this sentence under the Simulating a Heavy Task section-
The TaskBean class also implements the java.io.Serializable interface so that it can be used as a JavaBean in the JSP pages

I feel that the sentence is misleading.
What do you guys feel.
bye

You don't HAVE TO but under heavy load, low memory conditions your servlet engine will try to save a session by serialization, losing any non-serializable beans. This will result in mysterious malfunctions that you will never see in low load testing.

I guess this(Saving a bean under heavy load) is not a part of spec.
