Subject RES: Using EL
Date Mon, 07 Jun 2004 13:54:25 GMT
Hi Keith,

It also happened to me. To solve that I had to add some "DTD properties"
(not sure if it can be called this way) to the <web-app> tag in web.xml,
like this:

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
      http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    version="2.4">

.
.
.
</web-app>

Hope that helps...

Marcelo
