Question

I am wondering how I can iterate through a list array in a jsp page, where the list is defined in a custom java servlet.

This is what I have in the servlet:

request.setAttribute("TITLE", STRINGVALUE);

I can display the above code fragment with the following line:

${dashboard}

Now I am trying to use a foreach loop:

<c:forEach var="VARIABLE" items="??????">

The question consists of two sub questions:

1. How can I use an array in the foreach statement, without using scriptlets?
2. How can I print values of the array elements? For example, ${person.name} results in an error, as the program only sees a String.

Basically, you need to have the List of your Objects in your session.

Ex.

List <Persons> myList = new ArrayList<Persons>();
myList.add(p1);
myList.add(p2);
session.setAttribute("persons", myList );

And then in your jsp you use it like this:

<c:forEach items="${persons}" var="personBean">  
  ${personBean.lastName}, ${personBean.firstName} <br />  
</c:forEach>
