I am looking for a quick and dirty way to allow a user to enter something in a text field, click a button, and have some results be displayed based on what is entered. How do I accomplish this with scriptlets in a jsp? Thanks.

You can’t make scriptlets (java code snippets in
<% %>) execute in any other moment than the moment when the server is preparing the jsp to be rendered.In case you want to get the results server-side, you could, for instance:
actionattribute:<form action="myServlet"><input type='submit'>button in the form.myServletservlet, retrieve the textfield’s value (request.getParameter()) and perform the search. Make a request to another/the same jsp and put the results in a request attribute<% request.getAttribute(); %>UDPATE : Take into account that scriptlets are considered poor practice, use JSTL tags and Unified Expression Language instead.
