Re: JSTL XML ---org/apache/xpath/XPathException
Make sure that you have *both* Xerces and Xalan installed. You can put
the JARs in Tomcat's common/endorsed directory.

I have downloaded these jars from the site http://www.apache.org/dist/xerces/j/
Can you tell me whats the purpose of endorsed folder. cant these jars workout
if they are placed in tomcat/common/lib directory ??
Thanks Regards

Re: JSTL XML ---org/apache/xpath/XPathException
When Tomcat starts up, it sets the java.endorsed.dirs system property
to its common/endorsed dir. Check this out:
http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html#XML%20Parsers%20and%20J2SE%201.4
You could also try putting the JARs in your app's WEB-INF/lib dir
(this would be the preferred approach if you couldn't install them on
the server).

Re: jstl x:parse outputs data
Thanks Kris,
x:parse tag is now silent :-)
however, I can't get x:out to output anything, it throws
ERROR: Nested in javax.servlet.ServletException:

Re: jstl x:parse outputs data
You don't need those taglib entries in web.xml. Remove them and use the
proper JSTL 1.1 URIs:
jsp:root xmlns:jsp=”http://java.sun.com/JSP/Page”

Yeah, I suppose that's a good reason not to have an escaped output. Thanks for the info.

Re: JSTL 1.1.2 c:url problem?
c:url by default doesn't encode the ampersand.
However, there are options available in the current implementation of JSTL1.1
which allows you to obtain an
ampersand escaped URL.
1) In reference to the code you've mentioned, one option is:
c:out var=link escapeXml=true /
So you'd essentially have a link like this a href='c:out var=link
escapeXml=true /' Link Text /a
2) Here's a shorter option:
${fn:escapeXml(link)}
a href='${fn:escapeXml(link)}' Link Text /a
This second option requires the functions Tag Lib.

Just out of curiosity, is JSTL supposed to do encoding by default?

RE: JSTL problem
I suggest you remove the if it is actually in your JSP.
Also, change this: core:out value=${languaje.descripcio}:/
to this: core:out value=${languaje.descripcio}/:
This may also also be a problem: webLangId${languaje.codi}
Try ${ 'webLangId' + languaje.codi }
If you're using the 2.4 spec. you can try this:
input type=text name=webLangId${languaje.codi} size=64/
Just suggestions.

That seems to point to the forEach tag. Make sure the version of JSTL

2.4 Schema) that you're using for your app.

I'm not sure why this isn't working for you, but here's an example to
demonstrate that escaping should be taking place. Try this page:
%@ page contentType=text/plain %
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %
c:set var=chars'/c:set
Escaped chars: c:out value=${chars}/
Unescaped chars: c:out value=${chars} escapeXml=false/
The output should look like:
Escaped chars: amp; lt; gt; #034; #039;
Unescaped chars: '

Re: JSTL resource bundle issue
I have the following case: (1) I have an framework application which has framework resource bundle which sits in a jar file and also some framework jsps like header / footer etc.. (2) I have an application which uses the framework jar file and copies the framework jsp files over and has its own resource bundle.

Let me throw in a couple of points just for sake of discussions, though. If you think I am totally off the mark, just let me know... My understanding is that there are a few tag-libraries that break MVC out there. The SQL tags are a great example of this (embedding SQL in JSP? are we back to MS ActiveServerPages?!?! :) Now, wouldn't creating tags that allow a certain amount of basic file manipulations fall in the same cathegory as the SQL tags? I mean, after all, there even is no guarantee that there's an SQL DB the webapp can talk to. Those tag-libs would still be good to have in the toolset for quick and dirty tasks (prototyping for examples), even though they are far from ideal in many cases... Just my 2 cents of euro.

Re: jstl doesn't work
Hi Michael,
Did you include the necessary taglib directives at the beginning of your
JSP? For example, to use the core taglib as you are doing:
[EMAIL PROTECTED] prefix=c uri=http://java.sun.com/jsp/jstl/core%
This needs to be included at the top of any JSP using the taglib. If you
already know this, I apologize. It was the only thing I could think of
that you didn't mention. Hope this helps.

Hello,
I am struggling with the JSTL error for the past two days. Can someone help
me in this?
In my JSP, I have the following code to populate bean array properties.
c:forEach var=vsr items=${vsroute}
c:catch var=coercionError
tr
tdc:out value=${vsr.fromcity} //td
tdc:out value=${vsr.tocity} //td

trtdRoute Disp Err :/td
tdbrfont color=#FFc:out
value=${coercionError}//font/td
/tr
/c:if
/c:forEach
The bean 'vsroute' is correctly built from the action.
I get the following error from the JSP
javax.servlet.jsp.JspException: An error occurred while evaluating custom
action attribute value with value ${vsr.fromcity}: Unable to find a
value for fromcity in object of class DBObjs.subscriber.vo.VSRouteVO
using operator . (null)
I did a google search on this and there was a suggestion that the older jsp
may be cached in tomcat work folder and I did remove that. Even then I get
this error.
I have around four rows in the bean array and I get four times the above
error as I am catching the error within the forEach loop.
Thanks in advance for the help.

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.

Re: JSTL and Java Constants
I would like to do something like:
a) c:when test=${item.type == ContentType.URL}

One big tradeoff with that approach is that you have to specify your
constants in one Constant class where they may not naturally belong. Another
one would be that you would have to import all external constants into that
class, thereby creating double maintenance work. And a third would be that
you'd need to import the constant class at the top of each page.
My workaround for the fact that you directly can't reach a static variable
in a java class is to make invoke a static method through the EL which in
turns does some reflective parsing to find the constant. It would look like
this:
c:when test=${item.type == fn:const('URL')}
You could create several different extractor methods to have different level
of generality in the method so that you can reach constants in a predefined
class, in a package, or with the full class name:
c:when test=${item.type == fn:const('ActionHandler.URL')} or
c:when test=${item.type == fn:const('java.lang.Integer.MAX_VALUE')}
With this approach you are guaranteed to not have any hard coded magic
values in your jsp. I do not have the code that does the extraction here at
my work, but if you are interested, I can send it over or post it here.

The big tradeoff is of course the extra fn:xxx('...') that needs to be
written in the code. But a big plus is that once direct retrieval of
constants from java classes is integrated into the EL, a conversion is
simple a matter of search and replace.
I've extracted the relevant classes into a package attached to this message,
although I'm not sure if this list accepts attachments. The classes have
been extracted from a larger context and converted from Java 5 and may
therefore be erraneous, although they have been tested.
Second, the implementation could have been simpler, but it was built with a
field cache to make sure repeated retrieval of fields is efficient, so I
included that cache too.
If you have any questions about the code, please feel free to ask.

A few example ways to extract the constants are included, with the java.math
package as example. Every invokation of a field is stored in a field cache,
since reflection may be a bit slow. This cache is listed in the three
following files. But as mentioned, they are really not needed if you want to
make the implementation simpler. Then the reflection code can be
incorporated

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

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}

Done. I think. At least, everything seems to have worked out, so it should
be available in the next nightly build of Unstandard.

RE: JSTL 1.0 problem with Bayern Ch 11 example...
I'd have to agree with you on that one.
I downloaded Tomcat 5.0.28 from the site, http://jakarta.apache.org/tomcat ,
then dropped the pages into the ROOT folder, along with my JSTL 1.0 libs (from
jdev 10.1.2). Once I tweaked the jsp page (for parsing) to use a different URI
for the TLD - as noted in another site), the page worked as you said. [NOTE
that it appears I'm not really comparing apples to apples here as I'm using a
NEWER container (servlet 2.4/jsp 2.0) and an old JSTL version to compare
against OC4J 10.1.2, which I think is Servlet 2.3/jsp 1.2, but still, it works.
Thanks for the quick response yesterday!!

The reason I tried to do this simple example was that I was creating a

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

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.

RE: jstl and splitting carriage returns
I had the same problem last week. For whatever reason (The JSP policy on
whitespace) I couldn't set a variable to \n but I could create one
using the following hack:
c:set var=temp value=one
two/
c:set var=newline value=${fn:substring(temp,4,5)}/
(Note that on my windows computer temp=one\r\ntwo so that the 5th
character is the newline character)
Then you should be able to split the string using this new variable,
e.g.
c:forEach items='${fn:split(feed, newline)}' var=row
c:out value=${row}/
/c:forEach

Re: JSTL - c:if test Question

Thanks for your prompt reply. Your sugestion was a good idea, but I
found that the following actually worked the way I wanted it to:
c:if test=${fn:containsIgnoreCase(restaurant.filterValue, param.value)}
Thanks,

Quoting Jack Lauman [EMAIL PROTECTED]:
I am using the following line of code to test strings for equailty.
In most cases I'm just trying to compare a city name in an array to
user input for the name of a city i.e. Seattle.
c:if test=${restaurant.filterValue eq param.value}
If the user enters seattle instead of Seattle I don't get a response.
Is there a way to alter this statement to make it case insensitive?
Is there a way to alter it to respond like a SQL %LIKE% query?

Re: JSTL 1.0 URI vs. JSTL 1.1 URI
Jason,
Make sure your deployment descriptor (web.xml) is servlet 2.4 based,
as follows:
?xml version=1.0 encoding=ISO-8859-1?
web-app xmlns=http://java.sun.com/xml/ns/j2ee;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;

http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd;
version=2.4
!-- web-app specific content --
/web-app
For an explanation of why this should solve your problem, please
see Appendix A of the JSTL spec (Compatibility and Migration).

Greetings,
I'm fairly new to JSP and the java paradigm in general, and am trying to get
my feet wet with some simple pages. I'm starting with tomcat-5.0.27 and
jakarta-taglibs-standard-1.1.2. I've followed the documentation at
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/appdev/processes.html on
putting together an initial application tree, I've put one page (index.jsp)
in ./web, I've put together build.xml, web.xml, and I've placed standard.jar
and jstl.jar from the taglibs package in my WEB-INF/lib dir.
I'm pretty certain I've got the basic structure down, but could be wrong.
The problem I'm having is this:
From what I've read, Tomcat 5.x utilizes JSP 2.0 JSTL 1.1. It's my
understanding that with JSTL 1.1, the taglib uri for JSTL Core change from
http://java.sun.com/jstl/core to http://java.sun.com/jsp/jstl/core.
Here is my index.jsp:
%@ page contentType=text/html %
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
html
head
titleFirst JSP Page Ever/title
/head
body style=background-color: white; color: black;
c:set var=test value=hello /
Following number uSHOULD/u be six:
c:out value=${1 + 2 + 3} /
br/
Following uSHOULD/u be 'hello':
c:out value=${test} /
/body
/html
I don't think you can get much simpler. However, with that page as it is,
the out put looks like this:
Following number SHOULD be six: ${1 + 2 + 3}
Following SHOULD be 'hello': ${test}
Now... If I change the taglib uri from http://java.sun.com/jsp/jstl/core to
http://java.sun.com/jstl/core, the output looks like this:
Following number SHOULD be six: 6
Following SHOULD be 'hello': hello
This has me perplexed. Was wondering if anyone out there could shed some
light on this behavior for me? Thanks in advance for your time and
thoughts.

RE: [JSTL] Retrieving the key from a LinkedMap for a known value?
Right, that's just not gonna happen with JSTL's EL. Well, I suppose you could
keep a shadow map that mapped values to keys, but that seems like a
management headache as well as a bit of session bloat. With JSP 2.0, you could
create an EL function to do it, but you're out of luck with JSP 1.2/JSTL 1.0.
Even programmatically, there's no straightforward method for getting the key of
a mapped value. You basically have to iterate through the entries looking for a
mapping that contains a value equal to one you're holding. You may want to
investigate writing a custom taglib for this if you really need this
functionality in a JSP. Other options are to use a Filter or Servlet (or a
controller component if you're using an MVC framework) to search for the key
and then set it as a request attribute for the JSP to use.

Is it possible to retrieve the key from a LinkedMap for a known value using
the expression language syntax under JSTL 1.0?
For example, I have a LinkedMap object which is being used to generate a
drop down with the input:select .../ tag from the Input taglib. Apart
from needing the value selected by the user from the drop down I need to
pull the corresponding key for display purposes on the next page along in
the food chain. As I've already got the key/value pairs in a LinkedMap
within the session context I was hoping to merely say well here is the
value from the drop down now give me the key which was used as the display

Does this sort of make sense?

the key-value mapping? Or maybe you can have a bean with both mappings:
UsersBean

+ userNameById: Map
if you really need it (it is, in case both key and value are valid codes
and not only final results).

How about adding some JavaScript to update the value of a hidden input to

RE: JSTL 1.1: diffs between c and c-1_0
Dirk,
Would you let me know which spec you refered to in this thread? I am trying to
understand a JSTL core taglib issue that we are having.
Our issue was resolved with the workaround: changing the URI attribute of our JSP
[EMAIL PROTECTED] directives from /jstl-core to http://java.sun.com/jstl/core; in
the pages where we used the setFormat tag.
Note /jstl-core was defined in our web.xml as
taglib
taglib-uri/jstl-core/taglib-uri
taglib-location/WEB-INF/tld/c.tld/taglib-location
/taglib
However, our specific issue (http://nagoya.apache.org/bugzilla/show_bug.cgi?id=15703)
was supposedly fixed in JSTL 1.0.5. Release notes:
http://jakarta.apache.org/taglibs/doc/standard-1.0-doc/ReleaseNotes.html.
Presumably this fix would not require the above workaround. I would have thought JSTL
1.1 would not have this seemingly similar kind of issue. It seems counter intuitive to
me that the URI should be a fixed value. Maybe I am missing something.
I have read how-to pages which say to do this, but I have not seen any specification.
Any light you can shed would be greatly appreciated.
Thanks in advance for any help,

I'm using too much JSTL 1.1, so I'll have to figure out how to get Tomcat 5.0 and IIS working. -- Kris Schneider mailto:[EMAIL PROTECTED] D.O.Tech http://www.dotech.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: jstl not working when i use a web.xml file
The web.xml has info about your application like the taglibs to use. So,
if you put an empty web.xml file the tags you used for your iteration
aren't converted to java code and compiled. :-)
Maybe if you don't put a web.xml tomcat includes a default one, I don't
know (or the IDE you are using).
For recompiling all pages... hmm... maybe there is a polite thing but what
I know is deleting the cached compiled pages. There are at
tomcat/work/host/app. I don't think it works for reloading the
web.xml. Any way, you wouldn't have to worry about recompiling jsps.
IDEs for Java (I use JBuilder 6) offers running and debugging with their
own tomcat servers. There are initiated every time you want to run or
debug. It's very comfortable to use it, you don't worry about reloading
and all that stuff.
Hope it helps!

Hello!

trying to use jstl stuff in a webapp on jakarta 5.0.27. i created my
directory in webapps and placed the two .jar files in the WEB-INF/lib
directory. from there, i just copied the SimpleRange.jsp file from the
examples into my webapps directory. i then stop and restart jakarta
and run the page. it works great! i get this returned:
Simple Range Iteration
1 to 10
1 • 2 • 3 • 4 • 5 • 6 • 7 • 8 • 9 • 10 •
however, if i create any sort of web.xml file inside WEB-INF for my
webapp (at least the variations i tried), the page does not work
properly. i created a very simple empty web.xml file like this:
web-app
/web-app
anyway, with a web.xml file present, i get the following when trying
to run the page (after starting and stopping):
Simple Range Iteration
1 to 10
${i} • ${i} • ${i} • ${i} • ${i} • ${i} • ${i} • ${i} •
${i} • ${i} •
what in the world am i doing wrong? also (unrelated) how do i force a
recompile of my pages?
thanks!

Re: jstl not working when i use a web.xml file
very cool! that worked...but why? none of other suggestions did. any
sort of web.xml seemed to cause the page not to work. but placing this
line in allowed it to work. i'm assuming this turns off expression
language?

Re: JSTL 1.0 and the function library
Hi Nick, You might find MicroNova YUZU (http://sourceforge.net/projects/micronova-yuzu) useful. It doesn't have indexOf either, though, so you may have to use regular-expression functions (codecs) such as String:match or String:split instead. Hope this helps. Best Regards, Makoto Nagata Nick Rapagnani wrote: Because of the difficulty I had integrating Tomcat 5.X with IIS 6, I had to use Tomcat 4.X instead. This means no JSP 2.0 and no JSTL 1.1. I had been using the function library for some things, namely trim, replace, indexOf, and substring. I am looking for a replacement library. The string library from Jakarta can do everything except indexOf. Does anyone know of a good function library that I can use? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
