Struts and JSTL

[Fabrizio Gianneschi]

Hello,
I've some questions to the author... I'd like to know how much effort we have to put when using JSTL instead of the default Struts Tag Library.
Is JSTL sufficient to cover all features given by the framework to the presentation layer?
Should we use both libraries? Are there EL interoperability problems?
Thanks a lot

EL language is part of JSP2.0 spec as prefered language. On a Servlet 2.4/JSP 2.0 container, all tags will be EL enabled, so Struts "standard" tags will accept EL expressions and automatically handle JSTL tags.
On JSP 1.2 container, you can use JSTL and EL-enhanced tags to get the same syntax. A JSTL implementation can be downloaded from jakarta-taglibs (1.0.x) and EL enhanced Struts tags from tag contrib dir. Struts 1.2 will include Tiles-EL tags that were missing from 1.1 struts-el contrib.
Web use those tags on our app without trouble and they're very usefull, as some logic that needed lot's of logic:xx tags becomes simple in EL.
When migrating to JSP 2.0 container, you will just need to change taglib directive on your JSPs to the struts "standard" tags.

Yes, I know that... unfortunately I'm still working with the 2.3/1.2 spec.

This is a good news, for me. Thank you
