I think dbtags are the most powerful tools for developing Web-DB programs. Why did developers stop creating this powerful functions?

Re: How to use index in EL expression?
Hi. Peter. It works well. Thank you very much! EL is fantastic! And now I have one more question. var parameter doesn't seem to accept EL description as following. Is there a smart way to resolve above description?

Re: How to use index in EL expression?

I'll check its correctly working.

Hello,
use a temporary variable as an “index”:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %>
EL Test
${param[paramName]}

Because we need to specify i concretely for getting data in above case.

Re: How to use index in EL expression?
Hello Kazuaki,
Can you not use i directly as you're already within el? I'm not sure
why you want to embed the el.

Using paramValues, it causes the same problem.
EL cannot be nested, so
cannot be compiled.
I think we need pre-taglibs-taglibs or EL can be nested for resolving this.

Re: How to use index in EL expression?
Hello Kazuaki,
Very sorry for the response. I'm teaching this material right now and
assumed this was a student request (I have 70 of them) and only now
noticed that this was on the taglibs mailing list. Again, so sorry.
The "advice" in the prior is still sound, but now very out fo context.
The reasoning is still good.
I really think something in your domain layer should be parsing your
params and cleanly taking care of this all. You can still provide the
cleaned up POJOS via attributes, and that makes more sense. If you're
entirely skipping regular servlets and allowing direct access to JSP
you can probably use something like
${paramValues.key[i]}
