Hello:
I am starting to use the JSLT. I made a page JSP of the following form:

When I go to have access the page, do not appear nothing. Already I tried for "pageContext" before "list" and "word". However, the Tomcat returned an exception.
What must I make so that my collection appears?
Thanks,

In another forum, it was suggest to me to use jsp:useBean tag. So my code became this:

Now it shows a table with rows and column... but no data! What can I do?
Thanks,

Rafael,
quite a while that I have not worked with jstl. Got example right.

The var="palavra"> is an assignment not an expression, I would say. If you say

I am guessing that palavra computes to null.

Manning.com sells a very good book about jstl for $20 as pdf.
Its written by the spec lead Shawn Bayern and it focusses pragmatically the jstl-user. I like it.

Thanks for the recommendation!
The issue here is between scripting variables and scoped attributes, which we call "scoped variables" in JSTL. The JSTL EL doesn't give you access to scripting variables, so if you create a variable in a scriptlet, you need to expose it either with <jsp:useBean> or with code like

<% pageContext.setAttribute("foo", foo); %>
Hope that helps!
