What container are you using? If you're using Tomcat 5, or any container that supports JSP 2.0, and you're using the Servlet 2.4 schema in your web.xml, then EL expressions in your JSP will be natively supported, without any additional jar files.
Also, if you're using a JSP 2.0 container, you should NOT use Struts-EL, as it won't work properly. You wouldn't need to anyway, as the normal Struts tags would work fine with EL expressions in that container. Concerning dependency on the JSTL, there is no other tag library that should be higher on your "no-brainer" list of dependencies. Without it, your code will be messier and harder to maintain. > -----Original Message----- > From: Francesco Pretto [mailto:[EMAIL PROTECTED] > Sent: Sunday, March 25, 2007 7:53 AM > To: user@struts.apache.org > Subject: Iterate and write indexed properties in place using > logic:iterate > > Hi!
