Is it possible to update the list in jsp?

[hariharan jayaprakash]

I have arraylist which is already set in controller side.

I need to update the same list(removing few elements in the list) in jsp based on few conditions like, the selected values in dropdown kind off.

How to update the list in jsp?. Is there any way to handle this using JSTL?.

Instead of using scriptlets, can i do this?

No, you are misunderstanding what JSP is and how JSP works. The JSP executes to generate an HTML page and send it to the browser. Once it sends the page, its work is done. Please read this article to understand how JSP operates and why what you are asking makes no sense.

Once you understand how JSP works, what you want to accomplish will need to be done my making request back to the server when page events (like selecting from a drop down) occur. You can either submit a form, make a redirect, or, if you don't want to unload the page, use Ajax.
