How do I retrieve information from a form in jsp. I'm using a <select> drop box. When the user selects something from it, I want the page to recognize what was selected immediately and reload the page. Also, how do I get the page to reload immediately? I guess you could say that the page is dynamic. TIA. Kevin

To retrieve form parameter in a JSP page use request.getParameter("param") where param is the name of the parameter. To automatically submit a page when a item is selected in a drop-down use the onChange event of DHTML. Then use javascript to submit the form. Example: <form name="testForm" action="action.jsp"> <select name="testSelect" onChange="javascript:document.forms['testForm'].submit();"> <option value="1">One</option> <option value="2">Two</option> </select> </form> I didn't test it so if it doesn't work exactly... oh well.
