The "EL" flavour tags allow you to use "expression language" (EL) in the attributes of the struts tags in a Servlet 2.3 container (which Tomcat 4.1.31 is). Once you upgrade to a Servlet 2.4 container (e.g. Tomcat 5.x), which comes with EL support provided then you will need to switch back to the "regular" flavour struts tags.
If you need/want to use expression language then yes its a good choice - as is using version 1.0.x of the standard tag library (JSTL). Both allow you to use Servlet 2.4 features before you actually upgrade to a Servlet 2.4 container. You can do one thing so that upgrading to a Servlet 2.4 container in the future is a painless exercise. That is to put all your taglib declarations into a separate jsp file (say "TaglibDirectives.jsp") as follows: ------ START TaglibDirectives.jsp ----- <%@ taglib uri=http://struts.apache.org/tags-html-el prefix="html" %><%@ taglib uri=http://struts.apache.org/tags-bean-el prefix="bean" %><%@ taglib uri=http://struts.apache.org/tags-logic-el prefix="logic" %><%@ taglib uri=http://struts.apache.org/tags-tiles-el prefix="tiles" %> ------ END TaglibDirectives.jsp ----- Then in your jsps where you use these tags, you simply include this directives jsp: <%@ include file="/TaglibDirectives.jsp" %> The advantage of doing this is when you upgrade to a Servlet 2.4 container, all you need to do is change this one file to switch back to the "regular" struts tags: ------ START TaglibDirectives.jsp ----- <%@ taglib uri=http://struts.apache.org/tags-html prefix="html" %><%@ taglib uri=http://struts.apache.org/tags-bean prefix="bean" %><%@ taglib uri=http://struts.apache.org/tags-logic prefix="logic" %><%@ taglib uri=http://struts.apache.org/tags-tiles prefix="tiles" %> ------ END TaglibDirectives.jsp ----- This also works well for the "JSTL" tags - because their URI changed from JSTL 1.0.x (for use with Servlet 2.3) to JSTL 1.1.x (for use with Servlet 2.4) Niall ----- Original Message ----- From: "Vano Beridze" <[EMAIL PROTECTED]> Sent: Sunday, May 08, 2005 7:41 PM > I'm new to struts. > I'm going to use only struts-el tags in my jsps. > The web server is tomcat 4.1.31. > > Is it a good choice?
