Re: Conditional formatting elements of a collection in c:forEach

Hello everyone,
I'm trying to display a list of items in a collection using JSTL.
Each item in the collection has x, y, z and id variables.
The user can choose whether he wants the display order (of the items
in the collection) to be
1) x y z
2) z y x
As far as I know the display ordering can be accomplished in two ways:
1) as shown in the code snippet below, create two different loops for
each display format. The drawback with this approach is that a lot of
the common stuff is duplicated between the two loops.
2) Have a c:choose , selection within a single loop, which decides
between the two formats. The drawback is that the the same condition
checking repeats for each loop iteration.
Is there a way to set the formatting outside the loop , and use that
format in the loop to address the two drawbacks above.
Assuming you have a resource bundle around somewhere, add two format strings
to the bundle, one for each of your two display orders; use a condition
('when', 'if' or whatever) to set a variable with the appropriate key; then
use that variable to specify the key to fmt:message within your loop.

The Runtime Expression Evaluation column in the documentation refers to
JSP scripting expressions, not the expression language you are using.
If you're not already using JSP 2.x, I would recommending doing so and
ensuring that your web.xml file is referencing Servlets 2.4 and not an
earlier version.

Re: Var for c:forEach loop is always null
On 12/11/06, Neil Aggarwal [EMAIL PROTECTED] wrote:
Hello:
According to the c:forEach doc, the var attribute of the
c:forEach tag has nested visibility.
What does that mean?
From the spec:
Nested scoped variables are only visible within the body of the action and
are stored in page scope.
I am trying to access the current object of the iteration
and always getting null.
Here is an example:
[EMAIL PROTECTED] language=java %
[EMAIL PROTECTED] import=java.util.* %
[EMAIL PROTECTED] uri=http://java.sun.com/jsp/jstl/core; prefix=c %
%
HashSetString mySet = new HashSetString();
mySet.add(Str1);
mySet.add(Str2);
mySet.add(Str3);
mySet.add(Str4);
mySet.add(Str5);
mySet.add(Str6);
mySet.add(Str7);
request.setAttribute(mySet,mySet);
%
c:forEach var=str items=${mySet}
% String str = (String)request.getAttribute(str); %
p
%= str %
/c:forEach
The value of str is always null.
How can I fix this?
Well, for starters, var is page scoped and not request scoped. But why are
you using JSTL for your loop and then using scripting expressions to access
the iterator values? If you use c:out value=${str}/ or even just ${str}
you won't see this kind of problem.

Re: looping on a list of lists (or accessing custom attributes of a list)
On 6/3/06, Luca Passani [EMAIL PROTECTED] wrote:
Hi guys, here is my big problem today.
I have a list the items of two kinds (with and without icons) which gets
turned into a list of lists.
[x , x, y, x,y, y, y, y,x, x,y] becomes [[x,x],[y],[x],[y,y,y,y],[x],[y]]
When I render the list of lists in my JSP, I need to understand which
kind of list it is I am dealing with.
That's when I had a brilliant idea.
Hmm... ;-)
Two suggestions:
1) Instead of extending ArrayList, just encapsulate it. In other words, add
a property to LinkWithIconList for the list, so that you can access the list
explicitly using ${sub_list.list} or something. This seems like the simplest
approach.
2) The Unstandard taglib in the Taglibs sandbox has an 'instanceOf' tag that
might be useful to you.
--
Martin Cooper
I defined to subclasses of ArrayList:
public class LinkWithIconList extends ArrayList {
public boolean isLinkWithIconList() {
return true;
}
public boolean isLinkWithoutIconList() {
return false;
}
}
(you can probably guess what the other class looks like :). And each
sublist is an object of the respective subclasses.
The rationale was to be able to do something like:
c:forEach var=sub_list items=${list_of_lists}
c:choose
c:when test=${sub_list.linkWithIconList}
render list with icons
/c:when
c:when test=${sub_list.linkWithoutIconList}
render list without icons
/c:when
/c:choose
/c:forEach
Unfortunately this doesn't work. ${sub_list.linkWithIconList} is
interpreted as an attempt to access to an item of the collection (and
not one of its properties):
javax.servlet.ServletException: The . operator was supplied with
an index value of type java.lang.String to be
applied to a List or array, but that value cannot be converted to an
integer.
So, the question for this respactable forum is:
- is there an easy way to achieve what I am trying to achieve?
- are there other ways to achieve my goals?

Because the JSTL spec defines different URLs for JSTL 1.0 and JSTL 1.1. ;-) -- Martin Cooper woodchuck __ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I beg to differ. If you're going to divide the world up into M, V and C, it
is certainly part of the view, since it has to do with which part of the
model is being presented to the user, and how to navigate within a portion
of model data.
This, and the first link from the comments, is an interesting discussion of
Web MVC:

people, what's the elegant way to do pagination with JSTL?
I am using struts, my Action generates a LinkedList which a JSP page
is supposed to visualize:
c:forEach var=item items=${content_list}
c:out value=${item.name http://item.name http://item.name}/br
/
/c:forEach
I'd like the JSP to recognize long lists and split it in pages, possibly
with backward and forward navigation. I would really like to avoid
scriptlets.
BTW is pagination part of the view or is it part of the business logic
according to struts?
Thanks

Re: Views outside the servlet container
On 8/31/05, Karianne Berg [EMAIL PROTECTED] wrote: Hi, I'm not sure if this is the right forum to ask this question, but I'll try anyway. I'm working on an application that requires me to place some of the JSPs outside of the servlet container, or at least in another context than the webapp itself. However, I can't find a way to do this. I have tried to use core:import, but this doesn't work, as the page at the url given is first rendered and then imported into the page. I need something that permits use of the variables sent to the including page in the included page. I tried with jsp:include, but this could only include pages in the app context. If anyone has any suggestions, I would greatly appriciate them. This isn't exactly a taglibs question... I'm pretty sure there's no way to do this. JSP pages compile to servlets, and those really need a servlet container around to operate properly. One of the main purposes of web apps and war files is to make the applications self-contained, but it seems that's working against what you are trying to do. When you refer to another context than the web app itself, what do you mean, exactly? If putting the presentation in a jar file that lives outside the web app meets this, and JSP is not mandatory, then you could try using Velocity instead, and putting the templates in a jar somewhere. Exactly where you can put this would depend on the particular servlet container you're using. -- Martin Cooper Best regards, Karianne Berg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: JSTL and Java Constants
Take a look at the 'bind' tag in the Jakarta Taglibs Unstandard tag library.
See:
http://jakarta.apache.org/taglibs/sandbox/doc/unstandard-doc/index.html#bind
I have a useConstants tag that I've been meaning to donate that exposes all
of the constants in a class, but I haven't got around to that yet.

Hi there, here is my big problem today. I am using JSTL in some JSPs.
SInce this is a struts project, I would
like to keep my views totally separated from the Java APIs. For this
reason, I need your advice about the
most elegant to compare a given object type (an int constant) with the
possible values using the COSTANT name,
instead of the corresponding int.
The API defines the types of my object as:
public interface ContentType {
public static final int FOLDER = 1;
public static final int URL = 2;
}
in my JSP I have (loop over collection of items with getType() returning
the type int)
c:forEach var=item items=${content_list}
c:choose
c:when test=${item.type == 2}
a href=${item.value}c:out value=${item.name http://item.name
}//a
/c:when
:
I would like to do something like:
a) c:when test=${item.type == ContentType.URL}
This won't work. I could hack it around with a scriptlet and an import
at the top of my JSP, but that seems to me like
violating the separation between View and Control
b) I could do something like this in my action:
String type_url = 5;
request.setAttribute(url, type_url);
and then c:when test=${item.type == url}
but makes me wonder if having this code in the action really makes sense.
Any ideas?
Thanks

interesting. Do you have an example of how that should be used?
I believe it's something like:
un:bind var=TheConstant type=com.yourco.ContentType field=URL /
and then you can use 'TheConstant' when you want the value.
My useConstants tag works like this:
un:useConstants var=TheConstants className=com.yourco.ContentType /
and then 'TheConstants' contains a map of all constants in the class, so you
can use, for example:
${TheConstants.URL}

It looks like there's a bug in your container. I just tried out your

html
head
meta http-equiv=Content-Type content=text/html; charset=windows-1252
titleuntitled/title

body
form action=parseNumberCarefully.jsp method=post
Enter your favorite number input type=text name=favorite/
br/input type=submit name=submit value=Submit/

I created an parseNumberCarefully.jsp page:
%@ taglib prefix=c uri=http://java.sun.com/jstl/core%
%@ taglib prefix=fmt uri=http://java.sun.com/jstl/fmt%
html
head
titleparseNumberCarefully.jsp/title

pYou entered c:out value=${param.favorite}//p
c:catch var=parsingError
fmt:parseNumber var=fav value=${param.favorite}/
pAs far as I can tell, this corresponds to the number
c:out value=${fav}/.
/p
pIf you multiply this number by 2 and add 1, you get
c:out value=${fav * 2 + 1}/. I like that number better.
/p
/c:catch
c:if test=${not empty parsingError}
Sorry, this doesnrsquo;t look like a number to me. Perhaps
yoursquo;re in the wrong country?
/c:if
/body
/html
If I run the first page, enter a valid#, then click [submit], I get correct
results.
If I run the first page, enter an invalid # (i.e. abcd), then click [submit],
I get correct results.
However, if I enter an invalid#, click [back], then enter a valid number, I
keep getting parse errors. It's as if the catch keeps RECREATING the
parsingError exception on subsequent requests even though the data has
changed and is valid.
The reason I tried to do this simple example was that I was creating a
multi-record entry form, and trying to validate with JSTL. When I did this,
as soon as the form would detect bad data, every record after it would be
considered invalid data. In these cases, I'd end up either clearing the
rest of the data, or it would retain the first good data and ovewrite all
subsequent records, or I'd get a stack trace. I thought all of the code that
I was writing was syntactically correct, but it did not produce the results
that I wanted.
If parseNumberCarefully.jsp has an errorPage attribute defined, and you
remove the c:catch tag, and enter an invalid value, an error page is
displayed. Now, if you hit [back] to goto the entry page, and enter a valid
value, it works fine.
What am I missing?
I'd appreciate any assistance on this.
I'm running this against Oc4J (oracle jdeveloper's embedded server) for
Jdeveloper 10g, version 10.1.2, on a Windows 2000 box.

have to display a selectable list.. below was the original
struts code..
html:select name=entry property=type

Basically,thi swill lproduce a selectable list where the
selected value is the one corresponding to thep roperty..
am i correct that, if i want ot use JSTL, i have to use a
c:forEach for displaying the collection, and a c:if to test
teh value for each value in teh collection?
anyone can give any hints?

ooops, I felt this was a general taglib question, more than a Struts
question. It only takes struts as an example,

Sorry, I read it as why are almost all of the Struts tags based on
BodyTagSupport?, which would be a question for the Struts list. But I
guess I'll go ahead and answer that anyway, since it's probably the
simplest way to answer what you're asking.
The reason is exactly what you noted - that almost all of the tags
extend BaseHandlerTag, which has quite a lot of stuff in it. We needed
a common base class so that we could share all of that code, and not
have to reimplement the common attributes for each tag, and since some
of the tags process their bodies, there's no alternative but for that
base class to extend BodyTagSupport. We could have used two base
classes, but that would have meant duplicating code, and would no
doubt have led to the tags getting out of sync.
Rahul mentioned SimpleTagSupport, and that would have been nice, but
that came along long after the Struts tags, and indeed the Struts tags
still need to support earlier versions of JSP.
Hope that helps.

Re: Optimizing tag-lib performance
On 7/23/05, Luca Passani [EMAIL PROTECTED] wrote:
Hello again,
I would like to improve the performance of a tag-lib I have created.
What I would recommend is extracting the work of your tags into
methods that do not depend on the container being around. Then you can
write simple JUnit tests for that code, and profile it without the
container.
For example, in your refactored code below, pull all of the code that
builds up the string buffer into a separate method, and then only do
the out.print() from the JSP API method.
--
Martin Cooper
Some obvious optimizations would be to turn things like:
---
out.print( href=\+href+\);
//title is optional
if (!title.equals()) {
out.print( title=\+title+\);
}
---
into (is this what they call string internalization?):
---
final static String HREF_ATT = href=\;
final static String TITLE_ATT = title=\;
:
StringBuffer sb = new StringBuffer();
:
sb.append(HREF_ATT);
:
out.print(sb.toString());
---
Before I start applying these changes, though, I would like to be able
to sort of measure the improvements.
I tried something as basic as:
%
long startTime = System.currentTimeMillis();
%%@ taglib uri=/WEB-INF/tld/wall.tld prefix=wall
%wall:documentwall:xmlpidtd /
:
wall:body
wall:menu colorize=true autonumber=true
wall:a href=http://url1; title=GamesGames/wall:a
wall:a href=http://url2; title=HorosHoroscopes/wall:a
wall:a href=http://url1; title=KidsKids/wall:a
wall:a href=http://url2;
title=Movieswall:bMovies/wall:b/wall:a
wall:a href=http://url1; title=MusicMusic/wall:a
wall:a href=http://url2; title=RadioRadio/wall:a
wall:a href=http://url2; title=TVTV/wall:a
/wall:menu
/wall:body
/wall:document
%
long stopTime = System.currentTimeMillis();
long elapsedTime = stopTime - startTime;
System.out.println(elapsedTime);
%
the problem is that when I reload the page, the number of milliseconds
is zero and occasionally 8,9 or 10
(I see output in the tomcat console running on my laptop, so I am sure
that the browser is not caching).
Questions:
- is there something I am getting basically wrong?
- is my tag-lib optimized enough that I don't need to care about further
optimization? possibly
because the compiler/JVM already did the optimization for me?
- are there better ways/tools to measure tag-lib performance?
Thanks

Is there a reason why you are trying to use session
scope when there is no session?
My understanding of how the servlet works in term of a
session creation is that the container will create a
session every time when a new user access the server.
It seems to be correct from my short test with the
session ID. A session exists before accessing the JSP
file.
In a servlet, a session will be created on a call to getSession() or
getSession(true) if one did not already exist. In a JSP, if a session
does not exist and the page has session=true, one will be created.

You should take another look at your logging requirements and log what you need, when you need it. This sounds like you're logging every action that ever happens, all the time.

Re: question about integration with Tiles
A long time ago, we had the exact same issue with the Struts
html:form tag, since the form element tags wanted to talk to the
form tag itself. The problem also manifests itself when using
jsp:include, as well as Tiles. The solution we chose was similar to
what you suggested, except that we didn't bother with the
findAncestorWithClass() step.
I would recommend that you do the same. Just have your 'document' tag
store itself in request scope. There's no advantage to looking for the
class directly using findAncestorWithClass(), and there is some
performance hit for doing so.

Lately someone asked me if there is any way WALL can be used

WALL tags need to talk to one another. In particular, many
tags communicate with the containing top-level wall:document tag.
When a tag in a tile does a findAncestorWithClass(this, WallDocument.class)
to find the document tag, this obvously fails, because the tag is not there.
I think I have a workaround to this, but since tiles are not my
speciality and performance traps are always there,
I am about to ask this honorable forum for advice.
My workaround would be to have the document tag perform:
pageContext.setAttribute(wall-doc-ref-key, this,PageContext.REQUEST_SCOPE)
all the tags which need to refer to 'wall:document', could get a reference
to the tag through:
WallDocument document = (WallDocument) findAncestorWithClass(this,
WallDocument.class);
if (document == null) {
document =
(WallDocument)pageContext.getAttribute(wall-doc-ref-key,PageContext.REQUEST_SCOPE));
if (document == null) {
throw new JspTagException(tag 'menu' must be nested inside a
'document' tag);
}
}

- Will this work, as far as you can tell?
- is there a performance hit in doing this?
- can someone think of other solutions?

brinput name=colors value=Red
brinput name=colors value=Blue

brinput name=textures value=Smooth
brinput name=textures value=Rough

On the server, you can access the arrays as follows:
%
String[] colors = request.getParameterValues(colors);
String[] textures = request.getParameterValues(textures);
if(null != colors){
for(int i=0; icolors.length; i++){
%brcolor[%=String.valueOf(i)%] is %=colors[i]%%
}}
if(null != textures){
for(int i=0; itextures.length; i++){
%brtexture[%=String.valueOf(i)%] is
%=textures[i]%%
}}
%
I would like to know how to access these in Struts, the ActionForm, if
anyone knows if this is possible.
Yes, it's possible. Just make your action form properties string
arrays instead of strings, and it will just work. ;-)

Re: Processing output x:transform as JSP
It may be complicated, but it's the only way it's going to work. ;-) That is, short of modifying the container itself... If you think about it, it's not all that surprising. The page compiler generates Java code from the JSP page, and that Java code is compiled into a servlet. What you are asking for is the resultant servlet itself to have the capability to dynamically (at execution time) run the page compiler and then the Java compiler without actually having source files to start from, or class files to write to. Theoretically possible, but a huge amount of work - and a lot more complicated than generating JSP pages and running them through the container in the normal way! ;-) -- Martin Cooper On Tue, 31 Aug 2004 20:01:25 +0100, Graeme Andrews [EMAIL PROTECTED] wrote: Try saving the output to another jsp file (dynamic.jsp) and redirecting the client to that page It would be complicated to save the output to another jsp file and redirect to that because: (a) the output from x:transform is only a fragment of an XHTML page (b) in a multiuser environment I would be creating separate temporary files for each session and that starts to sound like maintenance nightmare.

From: Sergei P. Volin [mailto:[EMAIL PROTECTED]
I have a set of arrays of the same length and i want to
iterate over all of them in a turn.
So what is the best practice to do this?
Is there any direct method of direct acces to the element of an array?
Like this: c:out value=$myArray[i]
Are you sure this is the best design? If the arrays belong together,
then they probably shouldn't be lying around loose. Are they properties
of some object?
If this is the best design (or you can't change it), I think you can use
the 'varStatus' of c:forEach to address the other arrays. Off the top
of my head, and probably not quite correct...
c:forEach items=${firstArray} var=myItem varStatus=myLoopIndex
c:out value=${myItem}/
c:out value=${secondArray[myLoopIndex]}/
c:out value=${thirdArray[myLoopIndex]}/
/c:forEach
It might need single quotes around 'myLoopIndex'. Or not, play around
with it and see what works!
At the very least, you'll want to change the 'varStatus' value to 'status'
and change the 'myLoopIndex' usage to 'status.index'. The 'varStatus'
attribute exposes a structure rather than an index.

Subject: ${param.something} ... feature or bug?
Hi,
I am used to accessing form and URL parameters from JSTL using
${param.something}.
However, I've found if a form is enctype=multipart/form-data then the
parameters defined within the form tags are not accessible.
Say if I had a form field that was type=text (or hidden) then the value is
always empty when accessed from the JSTL.
I can see why this might be the case, due to the multi part and binary
files. Can anyone confirm that I will not ever be able to access these
simple form fields using JSLT when writing mlutipart forms? Or is there an
alternate syntax to do so?
The issue is that the Servlet spec does not address handling of multipart
requests, and so containers, in general, do not include transparent support
for that. Unless your container does have built-in support, or you have some
other pre-processor in place for multipart requests, you're not going to be
able to access parameters in such requests in the usual manner in JSTL.

RE: jstl output
Depending on your usage, you might be able to put a whitespace-stripping filter in front of your JSP pages, to collapse all this down. Alternatively, you could adopt the funky JSP coding style I've seen some people use, ensuring that you don't have whitespace between your tags. So instead of this: tl:one a=a/ tl:two b=b/ you would do this: tl:one a=a/tl:two b=b/ The first example causes the line break between the tags to be output into your page, which is where a lot of your \rs are coming from. The second example ensures that there is no whitespace between the tags.

Subject: how to nest a taglib in another taglib?
hi, thanks for reading..
i have a problem about nest a taglib in another
taglib, just like this, what should i do?
the attribute in the page context.
forum:hasContent content=c:out value=${attribute}
//forum:hasContent
This is not legal JSP (or XML) syntax. You cannot use an element as the
value of an attribute.
i know that has a way to do like this:
bean:define id=new_id name=attribute/
forum:hasContent
content==new_id.toString()/forum:hasContent
but there is another way to do it?
That depends on how the forum:hasContent tag is implemented. If that is
your own tag, and you are free to modify it, you could EL-enable that tag,
which would allow you to do:
forum:hasContent content=${attribute}/
A good example of how to EL-enable tags can be seen in the Struts-EL tag
library, the source code for which is available here:
http://cvs.apache.org/viewcvs.cgi/jakarta-struts/contrib/struts-el/
On the other hand, if the forum:hasContent tag is not under your control,
then you're probably stuck with providing a scripting expression (rtexpr),
which would look just like the example you give above.

dynaBean.setDynaActionFormClass(this);
FormPropertyConfig props[] = config.findFormPropertyConfigs();
for (int i = 0; i props.length; i++) {
dynaBean.set(props[i].getName(), props[i].initial());
}
return (dynaBean);
}
because the method setDynaActionFormClass is not defined in the
DynaActionForm class.
I am using struts1.1 with Tomcat 5.0. I looked for solutions on
the net but did not see this problem anywhere. Any guidance will
be greatly appreciated.

To: [EMAIL PROTECTED]
Subject: Re: Novice question about using Constants in when tags
Good question, Jeff. Unfortunately, there is not a direct way of doing
this. There are generally two approaches:
1) Store the values of the constants as application context variables
with the context being initialized through a startup servlet (or via a
Plugin if you were using Struts)
In the startup servlet you would have:
this.getServletContext().setAttribute(INTRO, new Integer(1));
then your JSTL would look like:
c:when test=${er.updateStatus == INTRO}
2) store a Map of these values in the application context --
something like:
Map constants = new HashMap();
constants.put(INTRO, new Integer(1)); //...
this.getServletContext().setAttribute(Constants, constants);
then your JSTL would look like:
c:when test=${er.updateStatus == Constants.INTRO}
3) Use the 'bind' tag from the Jakarta Unstandard Taglib to bind the Java
constants to scoped attributes. For example:
un:bind var=INTRO type=com.foo.YourClass field=INTRO/
Note, however, that Unstandard is still in the sandbox, and therefore
unreleased and subject to change.

public static final int INTRO = 1;
public static final int MISSING_EMAIL_ADDRESS = 2;
public static final int INVALID_EMAIL_ADDRESS = 3;
... so that I could do something like this...

pmessage three/p
/c:when

...which I thought would greatly improve the readability and
maintainability of my JSP page (it's easy to see that message 2
should be displayed if a Missing Email Address situation exists).
Those of you very familiar with jstl will no doubt recognize that
this won't work (something I discovered through trial and error).
Is there some way I can rewrite my expressions that works with
these constants?
Have you run into a similar situation and can you suggest a way
to make my crude code a bit more friendly?

The servlet spec would be useful for this. You'd want to start with

Since what you want to read is XML, you can do this as long as you actually
want to parse the XML as well. Try this:
x:parse var=parsedXml xml=${pageContext.request.reader}/
I'm not aware of any way of getting the raw content of the reader in JSTL,

RE: Problems with JSTL 1.1 and Tomcat 5 : UnresolvableException: $prefix:javax.servlet.include.query_string
I think this is what I was seeing when I was running JDK 1.4.1 instead of
1.4.2. I *thought* I was running 1.4.2, but it turned out that my path and
my JAVA_HOME environment variable didn't both say the same thing...

RE: tiles breaks x:forEach
Something's not matching up properly. The code below is for the very first
c:set in the JSP code you posted, setting the statesxml variable. That
doesn't correspond to the stack trace, since there's no XPath usage in
that JSP code at all.
Let's see if we can eliminate - or point the finger at - Tiles. Can you
try accessing the page using a jsp:include from another page, and see
what happens? I believe all Tiles is doing internally is an include (using
PageContext.include()), so this might provide some illumination (or not!).

Subject: RE: tiles breaks x:forEach
Well, I'm not sure this is helping you any, but I'm curious to see where it
leads ;-). I wish I knew a bit more about Tiles internals, I haven't really
used
it all that much. Anyway, the stack trace is still making me scratch my head
(order of execution):
JobSearch_jsp._jspx_meth_c_set_10(JobSearch_jsp.java:769)
JobSearch_jsp._jspx_meth_x_out_0(JobSearch_jsp.java:793)
...
XPathUtil$JstlVariableContext.getVariableValue
XPathUtil$JstlVariableContext.notNull
and the exception is thrown with message:
$prefix:javax.servlet.forward.request_uri
Which, AFAICT, means getVariableValue was trying to do something like:
return
notNull(pageContext.findAttribute(javax.servlet.forward.request_uri),
null,
javax.servlet.forward.request_uri);
Can you correlate lines 769 and 793 of the generated code with
JobSearch.jsp?
Huh, there seems to be a bug in the 1.1.0-B1 version of XPathUtil.
JstlVariableContext.notNull essentially looks like:
private Object notNull(Object o,
String prefix,
String localName) throws UnresolvableException {
if (o == null) {
throw new UnresolvableException($ +
(prefix==null?:prefix+:) +
localName);
}
return o;
}
Which means that instead of seeing the *value* of prefix in the exception
message (when it's non-null), you'll see the literal prefix. So it should
probably be:
private Object notNull(Object o,
String prefix,
String localName) throws UnresolvableException {
if (o == null) {
throw new UnresolvableException($ +
(prefix==null?:prefix+:) +
localName);
}
return o;
}
Obviously, that shouldn't be impacting your app at all, but you never know
what
you'll find when you go rooting through code...
Quoting [EMAIL PROTECTED]:
I'll take that into consideration but it doesn't solve the problem
of the forEach and out tags failing. I really need to be able to
to use these tags to select into an xml source for other reasons
besides building options for a select.
In ongoing research into this an x:parse fails with the same exception
on another page. Again if I change my struts action to directly
reference the jsp it works instead of a tile definition.
So I tried one step further and tried two different tiles definitions

Re: Variables for attributes in own tags
On Mon, 5 Jan 2004, Matthias Winkler wrote:
Hello,
I have some tags that create X+V form elements (mixed
XHTML and VXML). To name my form elements I want to
use names passed by an application. They are available
inside a bean. (struts application - values passed by
action form)
Along with the name more information is passed on to
the user. When the form is filled out the values of
the fields have to be sent back with the same bean.
If I use % out.write() % to write down my tag and
add the information from the bean, my tag will not be
evaluatet.
JSTL uses the ${} syntax to access information from a
bean and use it inside a jsp page.
I would like to do something similar but I do not
know, how to access the information from the bean when
I evaluate my tag.
At the end I would like to be able to do something
like: xv:input id=${mybean.name} ... /.
Where can I find information on how jstl handels this
problem?
This isn't hard to do, assuming you're OK with using the Jakarta Taglibs
implementation of JSTL. For an example, you might want to take a look at
the implementation of the Struts-EL tag libraries. These are just like the
regular Struts tags except that they allow you to use JSTL expressions in
the attribute values.
You can get the Struts-EL code by downloading the Struts source distro,
and looking under contrib/struts-el.
Hope this helps.
