escape tag
Is there a mode to reverse escape a string after the tag str:escapesomething/str:escape? I have to remove some char (\r\n) and then un-escape all the other special chars. Thank you again.

dbtags: How do I use the results to create a link?
Hi, I am using the dbtags library to query a database. I am getting a resultset and I would like to create a link to another page that contains the value of a database cell as a parameter.

I think you're looking for fmt:formatDate, not fmt:parseDate.

Yes - JSP tags within other JSP tags get evaluated by the container as
usual (and so your example will work) when the outer tag is declared as
having a body type of JSP (versus tagdependent) in its TLD.

Re: Nesting tags from different tag libraries?
Hi Eric,
It should work. I'm trying to work hard at making the String tag library
integrate as much as possible with JSTL as it seems to be the most common
place it gets used now. For example, I've copied the JSTL habit of being
able to place all output into a var variable, and there's a
StringTagSupport class there if you want to write your own string-based
tags.
Basically, if your example doesn't work for you, then it'll get fixed
pronto. However the way these things work is that the substring tag should
get the output of the c:out tag and not the tag itself.
Someone found a bug in this a week or so back, [the string taglibs fault]
so you might need to grab the latest jar file.

RE: Nesting tags from different tag libraries?
Ok, I now installed the String Tag Library, and it works fine on its own. I
installed it into my JSTL directory C:\Program Files\Apache Tomcat
4.0\webapps\jstl\ and put the *.war into C:\Program Files\Apache Tomcat
4.0\webapps\ (where I also put the JSTL standard-examples.war).
So now I can use the JSTL examples from
http://localhost:8080/standard-examples/index.html and I can use the String
Tag exmples from http://localhost:8080/string-examples/index.html -
everything works fine.
However, I tried modifying the Iterator example
http://localhost:8080/standard-examples/iterators/Simple.jsp to include
String tags, i.e. the first lines read
%@ taglib prefix=c uri=http://java.sun.com/jstl/ea/core; %
%@ taglib prefix=str uri=http://jakarta.apache.org/taglibs/string-1.0;
%
(I didn't write String tags yet, since I always take baby steps...)
and it crashes:

RE: Nesting tags from different tag libraries?
Making symlinks to the .jar files works too.
e.g. (we're talking unix/linux/MacOS X here):
while inside /usr/java/tomcat/webapps/foo/WEB-INF/lib
ln -s /usr/java/jakarta-taglibs/standard/standard.jar standard.jar
This is REALLY important, because each time I upgrade to a new version of
the taglibs, I only need to update the one in /usr/java/jakarta-taglibs/.
Whereas if I copied the file to all the different foo|bar|blort/WEB-INF
directories, I'd have to replace about twelve different files.
symlinks are your friend (I am sure Windows users can make a shortcut).

You need to install the individaul JAR files for all taglibs you want to
use (e.g., standard.jar jstl.jar, or string.jar) in the WEB-INF/lib
directory of your web application.
Once you've done that, your container should recognize the tag libraries.
Tomcat 4.0.3 has a bug whereby it doesn't recognize them by default unless
you modify your web.xml file, but Ryan Lubke posted a workaround yesterday
(And you can also upgrade to Tomcat 4.0.4B2).

getColumn
I don't understand how to use the to attribute.

String myValue = request.getParameter(bar);

sql:getColumn colName=blort to=myValue
This is the sort of thing I want to do, I think. But it does not work,
i.e. the string foo has a value bar and that ought to get written over
by the value of colName blort but it does not.
Basically what I want is to get each row value of the 'blort' column from
my blah DBtable, and write that to an option value.
In PHP, this would be:
$query = SELECT farble, blort FROM blah;
$my_result = mysql_db_query ($dbname, $query, $linkid);
echo select name=\whatever\;
while ($my_row =mysql_fetch_object($my_result)) {
$myValue = $my_row-blort;
echo option value=\$myValue\$myValue/option
}
echo /select;
Clearly to writes somewhere other than a scriplet variable.

Re: getColumn
Yes, the to attribute of the getColumn tag writes to a Servlet attribute,
not a scripting variable. A scripting variable would have been awkward
because the to attribute is optional; by default the tag will simply write
to the current writer.

This will install an extension to the ultradev tool, and a servlet in your app server. Then you would insert and manage your custom tags (like escapeSQL or struts or any other) from Ultradev, see the documentation it comes with a tutorial.

c:forEach compared to logic:iterate
I'm using the logic:iterate tag in the following manner:
logic:iterate id=pageInfo name=topicForm property=pages
html:link forward=getPage
name=pageInfo property=pageTopicMap
title=%=((PageForm)pageInfo).getName()%
c:out value=${pageInfo.pageSequence + 1}/
/html:link
/logic:iterate
Which works great! However, I was hoping to migrate my logic tags to
JSTL and the following doesn't work:
c:forEach var=pageInfo items=${topicForm.pages}
html:link forward=getPage
name=pageInfo property=pageTopicMap
title=%=((PageForm)pageInfo).getName()%
c:out value=${pageInfo.pageSequence + 1}/
/html:link
/c:forEach
However, I get the following error when I try this:

JSTL's c:forEach tag doesn't expose a scripting variable, just a scoped
attribute (which we call a scoped variable). You need to use
jsp:useBean (or some other declaration mechanism) if you absolutely need
scripting variables.
Though I can't speak for Struts, my sense is that it is planning to
accommodate JSTL's expression language (at the very least under JSP 1.3,
where it will be the container's responsibility), which will minimize the
need for scripting variables.
Hope that helps,

And will it behave differently if I set the scope as 'page' in the

There are two questions here, I believe.
The first is, What happens if I try to overwrite an existing scoped
variable (e.g., in application scope)? Here, the answer is simple: you
can always overwrite a scoped variable. Using c:set will either create
or replace a variable; nothing is sticky about the initial c:set.
The second question, I believe, is, What happens if I have an
application-scoped variable named 'foo' and try to set a page-scoped
variable named 'foo'? The answer here, unfortunately, varies by
implementation. The JSP standard technically provides for all scopes to
represent a single namespace: if there is a 'foo' object, it has a single
scope, and you can't have both ${pageScope.foo} and ${sessionScope.foo} at
the same time. However, because the specification doesn't mandate that
containers enforce this behavior, many don't, and (I would guess) most JSP
users expect each scope to have its own namespace.
The general advice that comes from all this is thus twofold:
- There's absolutely no problem overwriting scoped variables within the
same scope.
- Avoid, when possible, using the same name in two different scopes
to ensure your pages are portable from one container to another.
JSTL's tags, like c:set, are neutral on the issue. They don't enforce
more than their containers enforce. So they will let you create a
page-scoped 'foo' if you have an application-scoped 'foo' as long as your
container allows it; use this feature at your own risk.
