Security in JSP

Hi,

I was just wondering if anyone could tell me the security fall backs on JSP. I am trying to do a report on the differences in security between JSP and PHP. If anyone has experience in both and could compare them that would be even better.

thanks a million

Hi I am just starting with JSP and I was wondering if someone would be kind enough to help me. I want to use the get method to send a variable to the next page. I am making a website for football clubs and i have a database witht the following fields:

ClubID
ClubName
ClubManger

On the first page there is a list of clubs names. When you click on the clubs name I want it to bring you to the profile page of that club. So what i want is for when someone clicks on Arsenal, for example, their id number is sent onto the profile.php page and I can get the ClubName and ClubManager fields out of the database using the ClubID.

Please be gentle as I am only starting thanks!!

Thanks in advance,
