问题 I want to collect values from a JSP page and pass it dynamically to another JSP page with the help of JSTL. How can I do this? 回答1: You use a request scoped HashMap for that. Example 1) Declare the HashMap in each JSP you want to insert or access the list of values. <jsp:useBean id="map" class="java.util.HashMap" scope="request"/> Note: The scope="request" is what makes it accessible in other JSPs. 2) Stuff information into the HashMap <c:set target="${requestScope.map}" property="city" value

问题 I'm using a display:table , just to display tags. In my scenario I have 7 columns. For the first column, I get the values at runtime. For example I have these values in my manualASNListUID.instanceType that is an arraylist(manualASNListUID) and object(instanceType) . The column values are Early ASn, Late ASn, Sum. Otherwise Early Asn and Sum or else Early ASn, Late ASn, CMMS and Sum. How can I set the 'Sum' values as display in the last row? For example my table: Instance Type Sep-23 Sep-16
