Use while loop in jsp code
While loop is a control flow statement that works
repeatedly based on a given boolean condition, loop will continuously execute
the statements given in the body as long as a given condition is true.
While loop checks the condition before the body
execution so this is also called pre
test loop. This is the main difference between while and do while
loop, do while loop first execute the loop body then checks the boolean
condition.
Before run this jsp code create a new directory named
"user" in the tomcat-6.0.16/webapps and paste WEB-INF directory in
same.
