Hi,

I'm using JBoss Eclipse IDE 1.6

CODE :


at my class declation it says "The serializable class Controller does not declare a static final SerialVersionID field of type long"

What does that mean ?? what is the use/benifit of declaring serial version id ???

By default, Eclipse encourages you to provide a serial UID for all serializable classes as this improves usage of serializable classes in the long run.

You can turn this warning off, or even make it an error if you like.

Moving to the IDE forum, not a servlet question.
