fmt:formatDate /
According the documentation of JSTL 1.0 The fmt:formatDate / should output a current date and time. But even in fmt.tld and fmt-rt.tld the value attribute is required. I downloaded JSTL final release yesterday. I am preparing a presentation of JSTL for my company development section, so I wouldn't like to any scriptlets as value="%=new Date()% " in my demo. Is it a JSTL bug or I am doing something wrong?

RE: fmt:formatDate /
Thank you very much for fast response,
It is not perfect but at least now I understand the situation.
I hope in future (1-2 years later :-) servlet container specifications
will be much better refined or JSTL will find some way around problem.
We use MVC approach and JSTL is used only for data displaying,
so we will use something like
fmt:formatDate value="${ now }" /
(ms are not important).
Thank you,
Yuri.

No, not in the final version of the JSTL 1.0 spec, available at
http://java.sun.com/products/jsp/jstl/. The behavior you describe
was in one of the preliminary versions of the spec but was removed
because of different interpretations between containers about how
a custom action with an empty body should be handled, leading to
portability problems.
But even in fmt.tld and fmt-rt.tld the value attribute is required.

You can create a java.util.Date instance that represents the current
time and then format it:
jsp:useBean id="now" class="java.util.Date" /
fmt:formatDate value="${now}" /

RE: EL
Thank you,
I understand.
Maybe a stupid question, but why Java is not used as EL?
Is not it possible to just generate JSP script in the page with
minor substitution of variable names to pageContext.getAttribute() calls?
Sorry I am not very professional in this area yet,
so just a question.
Best regards,
Yuri.

Hello,
how can I use JS functions in EL, for example:
c:if test="${ a.indexOf( b ) 0 }"
doesn't work.
Any ideas?

You can't. The JSTL expression language is really just for simple
references to request parameters, attributes, and other
commonly accessed
data. For more complex operations -- e.g., on Strings and
Collections --
I suggest using custom tag libraries. Having said that, the
EL may grow
slightly to include some common functionality, either for
JSTL 1.0 or JSP
1.3. These features are still being debated.

JSTP Resin
Hello, I downloaded JSP Standard Tag Library from Sun and installed it under Resin. But I can't run Examples (see error message at the end of the mail). It looks like web app listener specified in web.xml doesn't work... (no application object are created for examples) Is listener tag in web.xml (Servlet 2.3 Spec) supported by Resin 2.0.3? Should I register something in resin.conf?
