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 within your loop.

Re: Bug
Like I said before, make sure your web.xml file is referencing
Servlets 2.4or later. You can have all the latest software, but if
your
web.xml file is referencing an earlier version of the spec, it won't make
any difference.

Hi,
Am using every thing according to specifications. After
opening link below
http://jakarta.apache.org/taglibs/sandbox/doc/datagrid-doc/index.html#requirements
go to TagReference. There in the first row it was given as attribute
items wont support RunTime ExpressionEvaluation. But in the example
below that table it was given as
|
How is it possible. when i copied the same copied into my editor and
executed . I got an error which states that the attribute ITEM will not
accept
expressions.
|
*item* or *items*? What is the *exact* error message, and what is the
*exact* syntax you are using?
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" %>
<%
HashSet mySet = new HashSet();
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);
%>
<% String str = (String)request.getAttribute("str"); %>
<%= str %>
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 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:
render list with icons
render list without icons
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?

short answer: no. Though I'm not sure where that
Uh, that would be HTML...

Martin Cooper
But if you're using a 2.4 deployment descriptor -- check what's at
the beginning of your application's web.xml -- upgrading to JSTL 1.1
is as simple as downloading and replacing a couple of jar files...
And well worth it, IMO -- replacing all those ``

That's because, since you are using a file URL, the request is not being made via HTTP, and thus is not being processed by a container as a JSP page request.

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.

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] > >

Urk. I just checked, and it looks like Unstandard is not included in the
nighly builds. Glenn, if you're reading this, could you add it please?
In the meantime, I've put my local build up here:

That's fine. We can just show them how it should be done. ;-)

Isn't that effectively the same thing, once all is said and done? Wouldn't
accessing a Constants bean be identical to accessing the constants from a
map provided by this tag?

Well, I might have a go at adding it tonight, if I have time. It's been a
*long* time since I've tried to build Taglibs, though, so if I have trouble
with that, it might not happen, since I don't want to break the nightly
builds.

I believe it's something like:
and then you can use 'TheConstant' when you want the value.
My useConstants tag works like this:
and then 'TheConstants' contains a map of all constants in the class, so you
can use, for example:
${TheConstants.URL}

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.

Assuming a JSP 2.0 container, yes. Not on JSP 1.2, though (and of
course functions won't work in an earlier container, either). My guess
at this point is that Suneetha is not using a JSP 2.0 container, hence
the problems.

That's because you're using JSTL 1.0 URIs but trying to use JSTL 1.1
functionality. If you correct your URIs, it should work (assuming you
actually have a JSTL 1.1 implementation).

You don't need that. As I said, what you _do_ need is getters. Like:

You need to define getters for the properties you want to access via JSTL.

As Muz pointed out, request parameters are immutable, since they are a
representation of the request as sent by the client. If you need to
modify them, you'll need to first copy them to some other location,
and then base your logic on the copy instead.
However, I suspect that there's likely a better solution to your
problem, so you might want to explain what it is that you are
ultimately trying to accomplish.

The first thing that strikes me is how amazingly slow each of these steps is for just a couple of hundred rows! That suggests either slow hardware or lots of opportunity to speed things up. ;-) I won't try to help you optimise your database query - at least not on this list - but that has to be possible too, unless it's horribly complicated. Going from the result set to rendered HTML should be fast too, unless you're doing a lot of computation along the way, but you don't say what's involved there, so it's hard to tell what would improve it. Finally, the browser rendering performance depends a great deal on how you've structured your HTML, which again you haven't actually told us about. So basically, we're going to need more details to be of any help. ;-) -- Martin Cooper > Kind regards, > > Marius Botha > > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

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.

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.

That would be the correct assumption. ;-) WebSphere 5.x is Servlet
2.3/JSP 1.2, while WebSphere 6.x is Servlet 2.4/JSP 2.0.

Yep, you'll definitely want to move to the Struts-EL tags. It could
get quite confusing, trying to use the RT tags while you're using JSTL
elsewhere.

There are a number of matters which need to be discussed and ideas developed. Anyone who is interested is invited to subscribe to the general list at Jakarta (http://jakarta.apache.org/site/mail.html).

Re: DisplayTag - Table header and Option All

For example: I would hazard a guess that the values for 'Implementation-Vendor' and 'Implementation-Vendor-Id' are actually incorrect, and should reference the ASF instead, since the Jakarta Taglibs implementation is licensed under the ASL.

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.

By specifying that the page does not participate in a session, you are
deliberately stating that no session be accessible from the page. If
you want to access the session, you need to change this to "true".

Re: question about integration with Tiles
A long time ago, we had the exact same issue with the Struts
tag, since the form element tags wanted to talk to the
form tag itself. The problem also manifests itself when using
, 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.

I didn't mean Struts and JSTL shouldn't be mixed, I meant that you should either have Struts load your resources and use Struts tags to access them, or use JSTL to load them and use JSTL tags to access them.

Re: fmt:message not using correct locale
JSTL and Struts use different mechanisms to load their resource bundles, and cache them under different attribute keys, so it's not surprising that JSTL tags do not pick up Struts resource bundles. I would recommend that you pick one approach and stick with it, rather than trying to mix the two approaches. -- Martin Cooper On Fri, 15 Oct 2004 15:23:37 -0600, Kumar V Kadiyala <[EMAIL PROTECTED]> wrote: > Hello, > > I have a webapp which uses struts and jstl.

Yes, it's possible. Just make your action form properties string
arrays instead of strings, and it will "just work". ;-)

Clearly the HTTP spec can't say anything about the order; that wouldn't be meaningful. However, the HTML spec does state that the order of parameters is preserved.

Re: Looping with paramValues
I'm not totally sure what you're asking either, but you should note that the only difference between 'param' and 'paramValues' is that the values in 'param' are strings while the values in 'paramValues' are arrays of strings. In all other respects, they are the same. -- Martin Cooper On Fri, 10 Sep 2004 10:23:14 -0700, Nic Werner <[EMAIL PROTECTED]> wrote: > Hi, >Is there a '.key' accessor for paramValues?

Re: Processing output 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 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. > > > > Graeme > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Looking at the source code, I see that the code for capitalize and capitalizeAllWords is actually identical, so I'm not surprised that they behave the same way. ;-) If you could file a bug in the bug database, that would ensure that the problem doesn't get forgotten. -- Martin Cooper On Sat, 21 Aug 2004 09:51:52 +0300, lis <[EMAIL PROTECTED]> wrote: > Hi all! > > <%@ page pageEncoding="UTF-8" contentType="text/html;charset=UTF-8" language="java" > %> > <%@ taglib prefix="str" uri="http://jakarta.apache.org/taglibs/string-1.1"; %> > beautiful life > > produce: Beautiful Lifeinstead of expected: Beautiful life > > in other words behave as > > any suggestions ? > > -- > Best regards, > lis mailto:[EMAIL PROTECTED] > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Nested expressions
Uh, your condition is what's wrong. The parameter key is *always*
going to be either not 'view' or not 'perPage' - it can't be both at
the same time. I think you mean AND instead of OR...

Re: Question about Mailer Tag library.
I'm not in a position to try this out right now, but you should be able to do this, since the address strings are passed directly to InternetAddress.parse(). You will need to be careful with the '<' and '>' characters, though, so that they're not interpreted as HTML or XML. -- Martin Cooper On Wed, 4 Aug 2004 15:14:16 -0500 , [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > Hi, all, > > I am writing a simple jsp making use of the Mailer Tag Library to send out > emails.My question is: Is there any way to put the sender email address in a > format like: "Myname <[EMAIL PROTECTED]>" instead of "[EMAIL PROTECTED]" > only?

Re: Xtags Id Variable is Obscured
I don't know how to solve your problem, I'm afraid. I just wanted to point out that I've noticed similar behaviour when using the tag, and not using xtags. I believe there is something odd happening under the covers when is used that can interfere with the behaviour of subsequent parts of the page.

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'.

JSTL doesn't have the concept of forms, so I assume you're referring to HTML forms. A couple of things to note about the Back button: * If the request was a GET and the page was allowed to be cached by the browser (as determined by the HTTP response headers), then the Back button will not cause a request to the server, so there's nothing you can do. * If the request was a GET and the page was not allowed to be cached, a new request will be made to the server with the same parameters as the previous request. Then it's up to you to decide what to do. * If the request was a POST, the user will be asked if they want the same form data posted a second time. If they accede, the request will be reposted with the same data, and you're in the same boat as above. -- Martin Cooper Jack - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If the IO taglib works for the XML-RPC invocation, then you should be able to use JSTL instead of XTags to parse the output. -- Martin Cooper > > Tnx > Benny - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

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: how to set the session of pageContext without the TagSupport in the custom taglib?
I'd suggest reading up on JSTL a bit, since it seems you're missing some of
the basics. The expression language (EL) in JSTL isn't Java, and the
implicit objects are not the same as those in JSP scriptlets.
To learn JSTL properly, I'd suggest reading "JSTL In Action" by Shawn
Bayern, or just reading the spec, if you're not up for buying (or borrowing)
a book. If you want to short-circuit learning it properly and just solve
your immediate problem (which I would not recommend), you could refer to
Appendix A of Shawn's book, which is freely available on the Manning web
site.

RE: String TagLib Dynamic String Replacement
It's not legal to mix string literals and scripting expressions in the value of a single attribute. The value must be one or the other. Paraphrasing your example a bit, to simplify, you have something like this: which mixes the two, so you need to convert it entirely to a scripting expression like this: -- Martin Cooper > -Original Message- > From: Joe Dittmann [mailto:[EMAIL PROTECTED] > Sent: Thursday, April 15, 2004 2:27 PM > To: [EMAIL PROTECTED] > Subject: String TagLib Dynamic String Replacement > > > Hello, > > > > I am having a problem replacing data dynamically in a string. > > > > \" class=\"more\">More > "><%=childGroup.getDescription()%> > > > > None of the scriptlets are evaluated. > > > > Throwing this error: > > > > /tiles/productCategory_content.jsp(120,14) jsp.error.unterminated.tag' > > > > > > Here is the tld: > > > > > > truncateNicely > > org.apache.taglibs.string.TruncateNicelyTag > > JSP > > > > var > > false > > true > > > > > > lower > > false > > true > > > > > > upper > > false > > true > > > > > > appendToEnd > > false > > true > > > > > > > > Many thanks in advance, > > > > Joe > > > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Is one preferred over the other? I'm not sure what you mean. JSTL can use and manipulate JavaBeans - they're complimentary technologies, rather than alternatives. Perhaps if you could describe a little about what your page is doing, or even provide a piece of it for us to look at, we'd be able to better help you decide on the best approach. -- Martin Cooper > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
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: you would do this: The first example causes the line break between the tags to be output into your page, which is where a lot of your "\r"s are coming from. The second example ensures that there is no whitespace between the tags. The obvious downside to this is the substantial decrease in readability... -- Martin Cooper > -Original Message- > From: Lorenzo Sicilia [mailto:[EMAIL PROTECTED] > Sent: Friday, April 09, 2004 3:28 AM > To: Tag Libraries Users List > Subject: jstl output > > > Hi to the list, > > I have a jsp with jstl.

That depends on how the 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: 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 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. -- Martin Cooper > please help methanks! > > > > __ > Do you Yahoo!? > Yahoo!
