send parameter from jsp to servlet using jsp:useBean

I am beginner in java and trying to figure out how to send parameter from jsp to servlet using this

inside my jsp -

<%! String option;%>
<% option = request.getParameter("option"); %>
<jsp:useBean id="processBean" scope="session" class="helpers.ProcessBean" />
${processBean.processRequest(option)}

I want to send 'option' to processRequest but this way it is always empty string, so I am doing something wrong.Could not find anything online. Any help is highly appreciated.

Solution

  • Variable declared/set on the page's scripting language is not automatically available from EL. You can manually make it available via:

    <c:set var="option" value="<%= option %>" />

    before using it in EL.
