Passing an arrayList of JavaBean Object as hidden variables

Hi every body...

i have a JSP page..where i get an ArrayList of objects. These objects are of type javabean type...say of class CapacityReqdBean.java.

Now my requirement is that i want to pass this arraylist to servlet....but don't know how to do it.
can i pass it through hidden variable .

i am not in a position to use session..because on jsp page i would be having different radio buttons....and each button would be representing an arrayList.

Finally on click of a radio button....that corresponding arrayList has to passed to the servlet where it would be passed to a function.

how can i achieve this..please help me.

Short answer: no.

Browsers only send strings. You can serialize/de-serialize somehow, or send IDs and re-create on the server side somehow, but the browser will send only strings back to the server.

The Servlet API provides the session for passing references to objects to various servlets and JSP within the same web application.

This is all very basic stuff, have your read a tutorial on the servlet API?

Hidden variables are used in HTML pages to attach name-value pairs of strings to HTML form submission.

Hi william
actually i didn't want to use session.
But still can you mention which servlet API is used for this purpose.....may be i can get the result.

That makes no sense. A radio button con only represent a single string value. How is it representing an array list?
