Even if I select only one check box and and click the submit button, by default all checkboxes get selected.What could be the reason for this?

In a series of multibox elements, the property remains constant but the value must change. So, you need to change

If your web application is a Servlet 2.4 application, I'd recommend using the EL expression ${strInterest} rather than the scriptlet.
