jsp - Render html input based on request attributes -

so have form submits info server. after submit attributes filled in on request. i'd render or not render elements on page based on attributes.

basically i'd want this.

<% string productname = ""; if( request.getparameter("productname") != null ){ productname = (string) request.getparameter("productname"); } %> <input type="text" id="product" name="product" readonly="readonly" value="<%= productname %>" rendered="#{<%= productname %> not empty}"/>

is achievable?

i not know, did understand question, if am, think answered :)

just set input text element condition, if productname not null, show it, otherwise not.

if not right reply questuion, please more specific.
