I am new to JSP (actually learning) , and I am building a web application where a form has a series of check boxes whose values are dynamically loaded from the database .

Since these are loaded dynamically before the application starts I was wondering whether I should use a Listener Class that loads the requsite fields onloading and makes it available for the Context.

I was wondering

          1.If this is the way it is to be done
          2.If so could you give me some examples or pointers to this ....

Please Note : I am not using Struts or any other framework simply becase I want to learn it the hard way (basics without a framework ) then move on to a framework where the details are not hidden

Thanks

Hi,

You do not need any Listener for that. What you can do is that to call your Servlet first before rendering your JSP. Then the servlet will redirect you to the JSP where those dynamic checkboxes are going to be displayed.

Just for your information, if you want to load something when your web application is started, Yes, you can do that. Please have a look at the ContextListener and you need to register this Listener to your web.xml. But for your case, I do not think that ContextListener is required.

Sorry, it was ServletContextListener instead of ContextListener
