JSP - Multiple parameters from request.

jsp

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!
