JSP EL and autoCompletion

Question

In my servlet:

request.setAttribute("list", myList);

In my Jsp:

<c:forEach var="item" items="${list}">
   ${item.name} and ${item.address}
</c:forEach>

How do I get autocompletion for item.name and item.address in IDE (IntelliJ)?

Can I use <jsp:useBean> for any other feature to make the type of 'item' explicit?

item could be anything. Did you try with usebean? Did you check what, if any, options are available for item quick fixes? – Corrales

For IntelliJ, you can use comment annotations, such as this:

<%--@elvariable id="list" type="java.util.List<your.item.class.Here>"--%>

To get this automatically, IntelliJ should be coloring ${items} as a warning, since it wont have any idea what it is. Click on it and when the lightbulb pops up, click the option "Declare external variable in comment annotation." That will generate a comment annotation such as the one listed above.

This is awesome! In fact Alt + Enter (quick-fix) gives two options - declare external variable as (a) useBean, (b) comment annotation. – Beersheba

Yeah, I use comment annotations personally. – Fauman
