Indeed, your question is a red flag indicating that you are trying to created scripted pages, just without the script. Switching from scriptlets to JSTL/EL is not an end in an of itself, you do it to create simple scriptless pages, not just to do it. I am very interested in your answer to Ben's question.

Well, I know what it is and it ain't JSTL. No one uses OGNL over JSTL. OGNL is typically used by frameworks (Tapestry comes to mind, though they may have dumped it for T5). OGNL is a binding and expression language that was used heavily prior to JSP 2.0 and its Expression Language. Stripes used OGNL for binding but it was ...

JSTL is server side stuff. it means that if some page has JSTL within it, it comes to client after doing all processing at server-side. and the client get a simple HTML page. similar to scriplets. better do it with javascript on the client-side, and make sure to put validation at the server end as well. because never rely on just ...

You can use the (legacy) jsp:useBean for that. But I agree with Bear that it should be done at in a servlet. That's the right approach nowadays. There are utilities and frameworks available which can populate beans for you 'automagically', for example Apache Commons Beanutils. If you want to do it at a bit higher level, consider JSF or Struts. In ...

He meant scriptlets. Answer is simple: scriptlets are not part of presentation logic while JSP is a presentation technology. So with scriptlets you're in fact mingling business, database and/or utility logic in a JSP file, of which each essentially belongs in a Java class. With taglibs and EL you (greatly!!) improves maintainability, readability, reusability, replaceability and so on. JSP came around ...

A conversion to JSTL is more than just replacing inappropriate Java that's on a JSP page with a JSTL equivalent.

Processing data, including Calendars, is something that is more appropriately ...
