2nd Most Common Misunderstanding:
Translation/Request Time Confusion
What happens at page translation time?
JSP constructs get translated into servlet code
What happens at request time?
Servlet code gets executed. No interpretation of JSP
occurs at request time. The original JSP page is ignored at
request time; only the servlet that resulted from it is used
When does page translation occur?
Typically, the first time JSP page is accessed after it is
modified. This should never happen to real user
(developers should test all JSP pages they install).
Page translation does not occur for each request
