Are you submitting the form where this select is to a servlet or to another JSP file ?

You can access the value using the Expression Language (EL) : ${instance2}.
But you'll get the value, not the label. In your example, all options have the same value. You should give them different values.

Which index ?

It would be better if you could come up with a solution by yourself.

Where ? Maybe you should post your JSP code here.

Please do not post the same question more than once. I am closing this one so that any discussion can occur in the duplicate post.
