Use the acronym SCRAPROPE to remember the JSP implicit variables:
session
config
request
application
pageContext
response
out
page
exception
I should really credit Russ for coming up with the acronym. I think my attempts, SCORP RAPE and SPORE CRAP, weren’t as catchy.
As I previously metioned, I’m taking the SCWCD exam tomorrow. When trying to cram for any exam I like to make up short poems, acronyms or just random chains of though. For example, I know the difference between Mitosis and Meiosis because Meiosis begins with “Meow” which is what cats do and they have four legs… anyway…
My first thing to remember is that a JspContext has a findAttribute method that I can use to Pick the Right Scope Automatically.
The acroynym, PRSA, is the order scopes are searched for attributes: Page, Request, Session, Application. You know that the S stands for Session because you can’t put attributes in a servlet. This also allows you to remember which objects can have attributes.
