Hi,
I am using Jstl and I also have some own tags. The out put of my
tags are some variables. Which one of these methods is best to expose
these variables
1. To give them as TEI variables in a separate class
2. Use them directly in the jsp page using the
I am interested in knowing which
Thank you
I am using struts, and am relatively new to java, I have never dealt with a
map??, and don't know what JSTL is, but I am reading up on it now. If there
is a resource that shows something like this it would be appreciated.

That's an odd little wrinkle to the EL ;-). For a test, I put together a
JSP:
<%@ page contentType="text/plain" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%
map.put(new Integer(1), "One");
map.put(new Integer(2), "Two");
map.put(new Integer(3), "Three");
pageContext.setAt
i'm guessing that you are using Struts...so, why don't you just get those
fields out of the database in an Action class and set them as a request
attribute? maybe you could store them in a Map with constants in your JSP
as your keys and then use JSTL to retreive those values? If you're doing
that,
I am working on a project that requires many list boxes to be populated from
a database.
I have done a lot of readying on this and managed to create a taglib that
will get my database fields and put it into a dropdown list, but I have to
use Form Beans for validation, which I could not figure out
Thanks Serge. Your suggestion works great with one caveat:
I can't specify delims="\r\n" because those values are used literally.
However, this seems to work:
<% String newline = "\r\n"; pageContext.setAttribute("newline",
newline); %>

I believe you can do (with reportID a variable containing the key)
<:set var="laborReport" value='${mapOfLaborReports[reportID]}'/>
which is very different from (with "reportID" as the key)
<:set var="laborReport" value='${mapOfLaborReports["reportID"]}'/>
so to use 3 as a key

There is probably a real easy answer for these two questions, but I
searching the archives for a while hasn't helped...
1) I have beans in a map that are stored with integers for the keys.
For testing I can retrive the bean out fine with the key of "test" like:

Or something bean-based might work. Not sure if it's any better than writing a tag.
ExceptionBean.java:
---
package foo;
import java.io.*;
public class ExceptionBean implements Serializable {
private Throwable t;
public Throwable getThrowable() { return this.t; }
pub
There is currently no way to do that using JSP 1.x because it will not allow
method calling (including passing parameters) using EL.
However, this will change in JSP 2 as this will be supported.
So for now I guess your stuck with using a scriptlet or creating a simple
tag to do this.

When I did this, I used option #1. I kind of extended a controller tag I
had already built to do the work of replacing the "\n"s with ""s and
so on.

Hi,
I am using Struts DynaActionForm object dataForm (session scope) to hold a
form data. It is no problem to display that form bean property in the JSP
page by using the Struts bean tag .
However I'd like see how the JSTL works by using JSTL without specifying
scope , it gave me exception like
Erm,
Not really experienced enough with JSTL yet for that. What you're currently getting is
the exception.toString(). For the full stacktrace you'd need to do:
<%
((Exception)request.getAttribute("javax.servlet.error.exception")).printStackTrace(response.getWriter());
%>
How to express that in
Martin,
That worked, but I only see the first line of the stacktrace. Anyway to get
the entire stacktrace?
This is what I currently have:

Hey Jeff,
The exception is available as a parameter in the request attributes under
"javax.servlet.error.exception".

I would like to have an error page that handles exceptions that flows the

Then in the error.jsp have a line like :
