hello,
I an new to jsp. i have a simple web app which performs some operations on a book database ( bookid, bookname, author,price as fields of a table).my problem is when i want to update a table,i put a checkbox on a side along with columns.
when i select any one of checkbox and clicks on a submit button it goes to update page.here i want to set the book id to check box and pass it to next page.

so my question is how can assign a variable in scriptlet to a name or id of a html check box.


Thank you

Firstly, scriptlets? In 2012? Please read this JspFaq entry. No scriptlets should be used in any JSP code written after 2002.

Secondly, what you should do first is to figure out what the HTML to represent your display should be. All JSP does is to help you generate the HTML. So figure out what the HTML should be first, then figure out how to use JSP (with the JSTL and EL, not scriptlets) to generate that HTML.

Step 1: refactor the JSP to remove the Java code. Database access should specifically never be done in the view.

It is sorta covered in the JavaRanch Style Guide.
