EL - JSTL samples

Suppose you want to select the first element of a List to print it. Easy

 <c:out value="${myList[0]}" />  

It can get complicated if you have not a list but a map, with numeric keys - see here.

What about comparing strings :

 <c:if test = "${user.role == 'ADMIN'}">  

Comparing the above two for selecting an option in a drop down :

 <option value="${role}" ${role == selectedRole ? 'selected' : ''}>${role}</option>  

Notice this wont work with xhtml. See here for escaping quotes.
