Yeah, I figured it out. Thanks a lot for the response.

Nope. You are making a common mistake - assuming that scripting variables
and scoped attributes are the same thing.
The 'startPage' and 'endPage' variables that you are displaying using
System.out.println() are scripting variables. Scripting variables are not
visible to the regular JSTL tags - those tags obtain their attribute
values from scoped attributes (e.g. request or session attributes)
instead.
To have your loop behave correctly, you'll need to set startPage and
endPage as scoped attributes instead of scripting variables.

The RT libraries support Java expressions instead of EL expressions,
e.g. '<= request.getParameter("foo") %> instead of "${param.foo}".
But seriously, you can avoid a lot of problems by reading a bit
about JSTL before you use it. Sun's JSTL pages has lots of resources:

It looks like you're using the RT library, not the EL library.
Check your taglib directive. You should use the uri
"http://java.sun.com/jstl/core"; for the EL library.

Are you using the runtime version of the common taglib? That is what this

foreach Problem - Not iterating like expected...
I have the following code:
<%
System.out.println("Start Page: " + startPage); //DEBUG
System.out.println("End Page: " + endPage); //DEBUG
%>
<%
System.out.println("Looping..."); //DEBUG
%>
When I run this code, I get the following values printed out for start and
end:
Start Page: 0
End Page: 42
But, the code only loops through one time, instead of looping all the times
I would expect... Shouldn't it be counting up through all iterations between
0 and 42?
If I replace the begin and end with 0 and 42 like this:
<%
System.out.println("Looping..."); //DEBUG
%>
Then it loops as I would expect.
What am I doing wrong?
Thanks,
Hunter

access to nested objects
Hello All,
can someone clarify for me how to use an expression to get to a nested
field in a bean. For example, I have a bean "mapserviceDetailForm" with
a method that returns another bean "service", and I want to reference
the "name" field within the "service" bean.
I was trying variations on:
value="${mapserviceDetailForm.service.name}"/>
Can someone clarify for me?
Thanks!

Re: pushBody() and popBody() problems in BodyTag

In order to solve this problem, I implemented tag.
The following code is doEndTag() in the .
public int doEndTag()
throws JspException {
try {
BodyContent body = (BodyContent) pageContext.getOut();
try {
while (true) {
JspWriter writer = pageContext.popBody();
body.writeOut(writer);
body = (BodyContent) writer;
}
} catch (EmptyStackException e) {
// nothing to do
}
} catch (Exception e) {
e.printStackTrace();
throw new JspException(e.toString());
}
return SKIP_PAGE;
}
By using this tag, it became possible to display "test1" string.
But is this the best method ? Is this popBody() usage wrong ?
Is there any other better method ?
Thanks in advance

Java code can refer to the scoped attribute as
pageContext.findAttribute("anObject");
To get "typeB," you'd need to cast anObject to the appropriate type and
then call getTypeB().

Broken resource bundle selection algorithm in JSTL and I18N?
Hi, there seems to be a bug in the resource bundle selection algorithm of JSTL 1.0.2 and I18N (nightly build from Feb 7 2003) (do they have the same code base?). The libraries read the requested language from the first request they get. After that first request, the browser locale seems to be discarded and all replies are generated with the locale from the first request. The locale seems to be in application scope instead of request or page scope. Can anyone confirm that behaviour? More information can be found at http://issues.apache.org/bugzilla/show_bug.cgi?id=16849 By the way, Struts does not show that behaviour. It always replies with the locale provided by the browser. Kind regards, Hans - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
