RE: Help needed...
Hey Jacob,
What you want to do in my opinion is do a little reading to understand what JSTL
actually is. The specification is a very good place to start since it is clearly and
simply written. The specification can be found here:
http://jcp.org/aboutJava/communityprocess/final/jsr052/
Also, there are several really good books on JSTL. I personally never read them, but I
hear good things about Shawn Bayern's book:

Subject: Help needed...
Hi...
I am new to tag libraries... I need to do a iteration using
the iterator tag... If anyone of you can help that would be great...
Here's my question...
I have an arraylist something like this...
ArrayList valueList = (ArrayList) session.getAttribute(aList);
I generate a loop something like this...
table border=1 bgcolor=#cc width=75% align=center
tr
tdHere are the values.../td
/tr
%for (int i=0; ivalueList.size(); i++){%
tr
td%= valueList.get(i) %/td
/tr
}%
/table
Now, I want to use the iterator tag and generate a table
without using the for loop...
My usebean is
jsp:useBean id=first
class=com.xxx.xxx.business.FirstBean scope=session /
If anybody out there could help me with this simple problem,
it would be great...
Thanks in advance...

Feature request in c:url?
To be able to write correct XHTML 's in the querystring need to be escaped.
To do so, I use the following code:
c:set var=a value=A/
c:set var=b value=B/
c:url var=theUrl value=whatever.jsp
c:param name=a value=${a}/
c:param name=b value=${b}/
/c:url
a href=c:out value=${theUrl} escapeXml=true/Link to whatever/a
This will return a correctly XML / XHTML escaped URL:
a href=whatever.jsp?a=Aamp;b=B.../a
Would it be possible in a future version of the JSTL to combine these two
tags as follows:
c:url value=whatever.jsp escapeXml=true
c:param name=a value=${a}/
c:param name=b value=${b}/
/c:url
What do you think?

Hey Jeroen,
Sounds sensible, considering the fact that it is even a requirement of standard HTML
4.01. However, this is a modification of the spec I think. You might want to get in
touch with them, or try the taglib-dev dept.

Re: Feature request in c:url?
Jeroen,
This issue was first raised by Andreas in bug #23319.
(http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23319)
I've brought it up to the expert group and it will, as mentioned
by Martin, require a change to the spec.
I've just added a comment to that bug stating that
unfortunately the JSTL 1.1 Maintenance Release spec is now frozen,
and the fix will have to wait for the next release.
The change that the expert group has agreed on so far is to add
one new attribute, 'escapeAmp', to escape the ampersand character.
Default value will be false (to be backwards compatible).
HTH,
-- Pierre

Help with JSTL...
Hi.
I am developing a new application in Struts and just wanted to see how to implement
JSTL in my jsps... I am trying to iterate a loop using a jstl tag... I am specifying a
collection object in the items attribute of the iterator action. I get this following
error...
org.apache.jasper.JasperException: An error occurred while evaluating custom action
attribute value with value ${actual.name}: Unable to find a value for name in
object of class java.lang.String using operator . (null)
My jsp goes something like this...
table align=center border=0 cellspacing=1 cellpadding=1 width=748
tr bgcolor=#99
th bgcolor=#cc class=blueLink align=center width=User Name/th
th bgcolor=#cc class=blueLink align=center width=Password/th
/tr
c:forEach var=actual items=${loginForm.clientCollection}
tr bgcolor=#9EC6FF
td class=content align=left
c:out value=${actual.name}/br
/td
td class=content align=left
c:out value=${actual.password}/br
/td
/tr
/c:forEach
/table
where clientCollection is a collection from the form bean...
From the LoginAction, I am calling a method in businessBean which returns a arraylist
that I had already set it in the formBean collection...
My LoginAction is something like this...
public class LoginAction extends Action {
BusinessBean businessBean = null;
String name = null;
String password = null;
public RegisterResourcesAction() {
super();
}
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
ActionErrors errors = new ActionErrors();
ActionForward forward = new ActionForward();
LoginForm loginForm = (LoginForm) form;
HttpSession session = request.getSession(false);
name = loginForm.getClient().getName();
password = loginForm.getClient().getPassword();
businessBean = new BusinessBean();
ArrayList aList = firstBean.exeQuery(name, password);
loginForm.setClientCollection(aList);
forward = mapping.findForward(success);
return (forward);
}
}

Re: c:import: relative links inside WEB-INF don't work

The collection in the clientCollection property has to be a collection

referenced by standard JavaBean accessors.
From your error message, I'm guessing that clientCollection is a
collection of java.lang.String objects.

Re: Having trouble with Multiple namespaces reading XML source
Gavin, I cannot talk for the xtags taglib, but for the xml tags of the standard taglib (implementation of JSTL), you have to make sure you access properly a specific node by referring to its namespace using the name() and namespace-uri() functions in XPath. You may want to check that thread in the archive: http://nagoya.apache.org/eyebrowse/[EMAIL PROTECTED]msgNo=4049 The deferred section of the JSTL 1.1 change log (http://java.sun.com/jstl), says the following: Deferred Changes Provide adequate XML Namespace support for the XML actions JSTL 1.0 does not currently provide adequate support for XML namespaces in XPath expressions. Collaboration between the JSP, JAXP, and JSTL specs is necessary to come up with the proper solution. This will therefore be addressed in the next major revision of JSTL.
