Re: question

[Kris Schneider]

The next time you hit the page it works though, right? If you're tracking
sessions via cookies, subsequent responses won't need to do URL rewriting. It
actually looks like it's a server bug. Hitting

http://www.sun.com/im/sun_logo.gif;jsessionid=foo

works just fine (SunONE WebServer 6.0), whereas hitting

http://www.apache.org/images/asf_logo_wide.gif;jsessionid=foo

results in a 404 (Apache/2.0.48-dev (Unix)). Same here ;-) (Microsoft-IIS/6.0)

I'm following the recommendations laid out by Shawn
Bayern in "JSTL In Action", but I've run into a snag.

On page 136, Shawn recommends using the  tag
for referring to a directory named images in a Web
application:

Okay, that's good, but I use page-relative paths successfully with

using with scoped variables

[Christopher Stead]

Using nested tags, I am not able to access the value of a scoped variable 
set by the parent tag:




 

   
 PageContext.PAGE_SCOPE) %>" default="test"/>

 


I've looked at javax.servlet.jsp.jstl.core.TagLoopSupport and the source 
code is definitely setting variable scope, so what am I doing wrong?  I've 
also tried using pageContext.findAttribute("repo_names") but that didn't 
work.  My default value doesn't display either.

Thanks for your time and consideration.

Cheers,
Chris

Use JSTL to output a path in the containor

[Vernon Smith]

I need to out put a path inside of the containor. The path is 

" 
align="middle">

in the script form. If I use the c:out tag, the JSP page path is attached to the front 
of the path. I also have tried the c:url and have the same result. 

How I can get the path right using a JSTL tag?

Thanks,

Vernon

Yes, I am importing the core library, I have plenty of other  tags

Re: How to get the size of a java.util.List object in EL?

[Serge Knystautas]

Adam,

JSP 2.0 introduces the notion of functions within EL, and in step with 
that release, JSTL 1.1 will include some standard functions including 
size.  There are early releases like Tomcat 5.0 and Resin 3.0 that give 
you some features of JSP 2.0, although I haven't tried either. 
Hopefully the specs will get finalized to get these standards out there 
soon.

I'm not quite sure why EL doesn't like this but I think it's because the

than the actual size(), but that doesn't explain why it's complaining 
about an integer.

Hey guys,

I think this can be accomplished although not directly. I 
must admit it's a terrible hack, so decide for yourself if 
you want to use this. I don't exactly have a test situation, 
so I can't really test this, but try:


	


This only shows the count if there is at least one item in

RE: How to get the size of a java.util.List object in EL?

[Martin van Dijken]

Oops,

Guess I spoke a little too fast there. The count does not, like I thought, expose the 
list size, but the count of how many iterations have passed.

Sorry, no go,

Martin

RE: How to get the size of a java.util.List object in EL?

[Martin van Dijken]

Hey guys,


I think this can be accomplished although not directly. I must admit it's a terrible 
hack, so decide for yourself if you want to use this. I don't exactly have a test 
situation, so I can't really test this, but try:





This only shows the count if there is at least one item in your list, but I think you 
can check for yourself whether something was printed.

Greetz,

Martin

Hi guys

I think this has been discussed in this list about 3.7 million times, so
check out the archives...
The short answer is: You can't.

Best regards,
Eric

Hi Billy,

I don't know about this one. Maybe someone more guru-like will step up 
with an answer 8-)

I'm not quite sure why EL doesn't like this but I think it's because the 
List class is not a javabean - presumably EL looks for getSize() rather 
than the actual size(), but that doesn't explain why it's complaining 
about an integer.

Re: How to get the size of a java.util.List object in EL?

[Henri Yandell]

This has been on the list before I think. The recommended solution appears
to be to replace your List class with a ListBean which contains a getSize
method. Would probably be useful if Taglib project could have these
classes available for download. Anyone implemented these and feel like
offering them up?

Another option is to have a tag to get it. Maybe Xephyrus could add it to
their datastruct taglib:

It gives me the following exception...

Does anyone know how I could get the size of the List?

Internationalization

[Martin van Dijken]

Hey gang,

I've been busy doing I18N for our site using the JSTL internationalisation features. 
What I miss there and could really use is a tag-alternative for the ChoiceFormat 
java-class. If need be I could of course create one of my own, but if there is one 
already I'd really rather use it. Does anybody know of something like that?

Also, are the non-standard I18N taglibs deprecated or something? They're very similar 
to the standard ones, but have different attribs etc.

Greetings,

Martin van Dijken
