Yes, I suppose it might be useful in some cases. The operator would have to
be something other than the '+' sign, though, since JSTL wouldn't know what
to do with an expression such as 'x + y' if both 'x' and 'y' were numeric
strings. (Should it add the numbers or concatenate the strings?)

You can still solve the problem you suggested, though, by using an

I believe at least some of the JSTL tags require features only available in 
JSP 1.2, but I don't know the specifics.

Note that this list is quite out of date. There are at least two containers 
which are listed here as JSP 1.1 but which now support JSP 1.2 (Resin and 
WebLogic). Most likely some others have been upgraded as well.

This might be good as we are also struggling with this question.  I could
use a scaled version of JSTL ( especially the iterators and conditional
tags) if it is based on JSP1.1.

I'm sure Shawn will answer this in full, but as a side-topic, is it worth
Jakarta hosting a JSTL-cut-down for JSP 1.1?

Making a JSTL for 1.1 that is as close to the JSTL spec as possible?

JSTL/Standard not really JSP 1.1?

[Lawrence You]

I think this is more of a labeling issue on the taglibs page than 
anything else but I'm wondering if there's a way I can get the 
Standard Taglib to work with JSP 1.1.

I started to go down the path of using the "Standard" tag library 
from the daily builds but I'm not so sure I can use it now with what 
I know. I thought it would be compatible with JSP 1.1 simply because 
"Standard" is listed on 
 as being a JSP 1.1 Tag 
Library (on the left side of the page). That was an easy enough 
assumption, but when I got the nightly build last week 
(jakarta-taglibs-20020415.zip), I couldn't get it to work with my app 
server and realized by looking at the TLDs that the library was going 
to require JSP 1.2.

With some more careful reading on
,
 
it says "JSTL 1.0 Beta 2 uses features provided only by the JSP 1.2 
standard draft, so it requires a JSP 1.2 container. We recommend you 
test JSTL with Tomcat 4.0." OK, fair enough.

So checking with versions of the commercial app servers we're using, 
it seems like JSP 1.1 is the current version supported by most 
servers:  and double 
checking with the versions we're using for deployment, looks like 
that is reality. Even Sun's recent (3/2002) release of iPlanet 6.5 
only supports JSP 1.1.

So my choices today seem to be to not use JSTL or to try to see if I 
can get it to work on JSP 1.1. I think I know what the answer is but 
is it really possible to use the Standard taglib on JSP 1.1? Perhaps 
rewrite the JSP 1.2 TLDs into JSP 1.1-compatible TLDs?

Right - this is not possible under JSP 1.2; there's no way to handle it
consistently with the current version of JSP.  JSP 1.3 will make this
possible; in fact, I'm working now on adding this feature to a working
version of the JSP 1.3 reference implementation.

DBTags doesn't support the JSTL expression language.  It could, but it
would currently require modifications to DBTags.  If you use JSTL tags,
you can use the expression language, but the syntax is now '${a}', no
longer just '$a'.

Hope that helps,

Re: getColumn

[Carole E. Mah]

I forgot to state the most obvious fact when I posted this just now.

The crux of the problem is that I want to access the object (or String if
I cast it using Morgan's example) inside template content (i.e. inside a
plain HTML attribute value) rather than inside a tag from a tag library.

(i.e. I want to essentially say:
  $myValue
)

It does not seem like this is possible.

Re: getColumn

[Carole E. Mah]

So, then I guess my question is to either Morgan or Shawn.

Sun's Java Web Services Tutorial
(http://java.sun.com/webservices/docs/ea1/tutorial/doc/JSTL4.html)
shows that a typical expression language syntax for accessing an object
would be to use $ syntax, in their example,
  
which is highly preferable to
  ">
since the latter is horribly invalid, not well-formed XML, and too verbose
anyway.

However, using the DBTags tag library, I have been unable to get the $
syntax to work and have been forced to resort to the awful nested scriplet
inside the attribute value.

Do you Morgan, Shawn, or anyone, have any advice?

Thank you,
-Carole

IO Tags....talking to a password protected site

[Rajesh Kalluri manduca]

Hi,

I am trying to use the io tags to publish a dynamic jsp page to a static
html thru filewrite, the tag works fine.

Can any one tell me how to pass a username/password when talking to a
password protected site its basic browser based authentication like
htpasswd.


Also this jsp is in the same web application as i am using IO tags, is there
a work around for my problem

The Jive Forum software is a robust API for online discussion
forums.  I don't know how easily it would integrate in with JSTL.

Given the stage of the JSTL - I would say no, but looking at the specs, I would say 
this is about 1 day worth of work.

Does anyone of you know where I can find a discussion forum that

a) works with JSTL
b) can be associated to certain pages - we want our users to discuss news
items, and of course every thread is "glued" to a news item
c) works with a database (JBDC or JDO)

It depends on the container; on Tomcat, it very well might be more
efficient.

Is this "as designed" and if so, is this an efficient way - I'd rather
search the specific scope, probably more efficient.

Does jstl provide anything like "request.isUserInRole()"?  I know I can
use Struts'  or the taglibs  tag,
but wondering if JSTL is providing an equivalent.

Thanks,

Matt

The short answer is "request was changed to requestScope".

The longer answer is that you really should, in most cases, treat all
scopes as a single namespace.  But there are situations where you only
want to retrieve a value if it comes from a specific scope -- hence the
top-level objects.  They've been renamed to pageScope, requestScope,
sessionScope, and applicationScope, as described in the PFD spec.

Re: Mail Tag CC error

[Rich Catlett]

The setRecipientTag resets the value of the address to null after each 
use, so the tag itself can bereused.  I don't  know why it is not 
working for you.  I have never used orion.   My suggestion is if you are 
familiar with java to add some System.out.println() to the setRecipient 
tag and check the value of the address variable at different points. 
 Sorry I can't be more helpful.

RE: Mailer Taglib SecurityException

[Renick, Garrel]

Derek,

Rich was instructing you to turn on security debug in your Tomcat 
startup options so that any security violations are clearly indicated
in your logs. To do that, modify the startup file for Tomcat. For example, 
I use the following in my starttomcat.bat file so that security.debug is 
set to access, failure:

start %JAVA_HOME%\bin\java.exe -Djava.io.tmpdir=%CATALINA_HOME%\work\temp 
-Dcatalina.home=%CATALINA_HOME% -Djava.security.debug=access,failure 
-Djava.security.manager -Djava.security.policy==%CATALINA_HOME%\conf\catalina.policy 
org.apache.catalina.startup.Bootstrap start -config %CATALINA_HOME%\conf\server.xml > 
%CATALINA_HOME%\logs\jvmstderr.log

Review your startup file and make the appropriate change to the 
-Djava.security.debug option. After you do this, any security violations 
will be clearly indicated in your logs, such as logs/localhost_log.2002-04-24.txt. 
You will see the domain that failed and it should be simple for you to copy 
and paste the needed permission into your catalina.policy file. If you're 
uncertain what to put in your policy, send the offending stack trace 
to the list and I'm sure someone will help.

Garrel Renick

 Rich,
I'm running Tomcat 4.0.2.  I suspect that the security changes that you reference, 
below, should be made to the catalina.policy file.  Do you know what the change would 
be?  Also, do you know where, in the server.xml file I would turn on security 
debugging?
Thanks!

Discussion forum

[Eric . Lewis]

Does anyone of you know where I can find a discussion forum that

a) works with JSTL
b) can be associated to certain pages - we want our users to discuss news
items, and of course every thread is "glued" to a news item
c) works with a database (JBDC or JDO)

Thanks & regards,
Eric

In this case this is a solution. However, having a concatening operator
would be very helpful e.g. when you want to test the result e.g ${(x +
y) == 'asdfasdfsdf')}.

escape SQL

[tony]

OK so I think that I understand.

I must use the preparedStatement and the query tag from dbtags
in order to get escapeSQL to work.

I don't want or need them I just want a quick and nasty way of escaping '

Does anyone have a solution to this very common task (at least in French 
and some other languages)

TIA and sorry for the waste of time 

Tony

PS any one who writes a simple taglib for escaping ' in sql queries wins
my immediate estime =:-D
