public interface ServletRequest. Defines an object to provide client request information to a servlet. The servlet container creates a ServletRequest object and passes it as an argument to the servlet's service method. A ServletRequest object provides data including parameter name and values, attributes, and an input stream. In Java 6, imagine I have the following method signature:. public void makeSandwich(Bread slice1, Bread slice2, List<Filling> fillings, boolean mustard) I would like to know, at runtime, the value that was passed on to slice2 or any other parameter, the important bit here is that I want to get the value by parameter name.. I know how to get the list of parameter types with getParameterTypes or 1. getParameterNames() returns the names of the parameters. Not their values. Use getParameter(String parameterName) to get the value of a parameter. The javadoc is your friend. answered Aug 3, 2011 at 12:26.
