RE: EL

[Yuri Peter Kazakov <yk...@valuecommerce.ne.jp>]

Thank you,
I understand.

Maybe a stupid question, but why Java is not used as EL?
Is not it possible to just generate JSP script in the page with
minor substitution of variable names to pageContext.getAttribute() calls?

Sorry I am not very professional in this area yet,
so just a question.

Best regards,
Yuri.
