JSP - Multiple parameters from request.

 To access request parameters in you JSP files, you could do this below

String value = request.getParameter("value_to_acces");


To access multiple values for the same parameter, you could do this below


String [] values = request.getParameterValues("value_to_access");


For JSP best practice, you should not use scriptlets. Scriplets increases the design pattern called spaghetti.


 <c:set var="value" value="${param.value_to_access}"/>
 <c:set var="values" value="${paramValues.value_to_access}"/>


Hope this helps!
