You might want to try the new mailer2 tag library from
jakarta-taglibs-sandbox that has been uploaded recently. It is currently
only available from CVS. See http://jakarta.apache.org/site/cvsindex.html
for details.

Good luck and best regards,

Feature request in ?

[Vianen, Jeroen van]

To be able to write correct XHTML &'s in the querystring need to be escaped.
To do so, I use the following code:







">Link to whatever

This will return a correctly XML / XHTML escaped URL:

...

Would it be possible in a future version of the JSTL to combine these two
tags as follows:






What do you think?

Please try the latest Resin snapshot and CVS taglibs snapshot. Both contain
fixes you need to run the examples properly. Don't know about listener's
though.

[standard] Patch for source attribute to also honor URLs

[Vianen, Jeroen van]

Hi,

I had the following problem with the  standard tag: when importing
an XML file like this:

http://hostname/path/to/file.xml"; var="xml"/>


Where the (externally generated) XML file contains a reference to a DTD (and
hence the file should be validated). The parse statement should be able to
know where to find the DTD, but it couldn't as the DTD was relative to the
XML file being imported.

Below is a patch that will allow a user to do the following:

http://hostname/path/to/file.xml"; var="doc" />

It will read the file from the URL and perform any validation as necessary.
So, no more  necessary.

Of course, this might not be entirely the right way to use the source
attribute, but I saw no other way to do it.

Please review.

Here's the patch for org.apache.taglibs.standard.tag.xml.ParseSupport.java:

[standard] Null in Javascript scope patch

[Vianen, Jeroen van]

Hi,

I tried to use the EA3 release of the JSTL standard tag library in Resin
2.0.4.

My JSP more or less looks like this:

<%@ taglib uri="http://java.sun.com/jstl/ea/core"; prefix="c" %>
<%@ taglib uri="http://java.sun.com/jstl/ea/xml"; prefix="x" %>

http://localhost/path/to/file.xml"; var="xml"/>



... and some more XPath expressions



I was unable to get this to work due to the following exception:

TypeError: Cannot convert null to an object.

It turned out that a null pointer was stored somewhere in the JavaScript
scope for the (null) attribute "caucho.authenticator", which is a built-in
Resin attribute.

Below is a patch for
.../standard/src/org/apache/taglibs/standard/lang/javascript/JavascriptExpre
ssionEvaluator.java that fixed this bug for me. I don't know whether this is
the correct fix, but at least I was able to have my JSP working as I
expected.
