Summary: Invalid element in displaytag-el.tld
Initial Comment:
The <example> elements in the displaytag-el.tld are
invalid per Sun's tag library DTD. Below is a error
trace resulting from adding displaytag.jar to a JRun4
web application -
[2]jrun.jsp.compiler.JRunTagLibraryInfo$InvalidTLDElementException:
The tag example on line 244 is n
ot a valid TLD element

I have reopened the bug on the new jira tracker at
http://jira.codehaus.org/browse/DISPL-91 and I am
investigating the problem with jrun.
Please add the issue on jira to your watch list to be
notified about progress.

from http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd:
<!ELEMENT example (#PCDATA) >
from displaytag-1.0-rc1.zip:
<example> <![CDATA[
<display:table name="someList" export="true" id="row"
requestURI="MyAction.do">
<display:column sortable="true" title="ID"> <c:out
value="${row.id}"/> </display:column>
<display:column property="email" autolink="true"/>
<display:column property="description" title="Comments"/>
</display:table>
]]> </example>
Two things could be causing the fault with JRun:
- You can't put CDATA in a location where PCDATA is
expected
or
- You can put CDATA in a location where PCDATA is expected
but you can't leave characters such as the "<" and the "&"
unescaped (because the XML parser faults on an invalid
entity reference)
For me it's a moot point because I no longer use displaytag,
but I hope this might help other users.

<!ELEMENT tag (name, tag-class, tei-class?, body-content?,

which version of displaytag has this problem on jrun?

According to the displaytag team, their tld conforms to
Sun's DTD; so they
refused to make any changes. I unjarred their distro,
manually removed all the
<example> elements from their displaytag-el.tld, and then
rejarred the files.
That fixed the problem for me.

Still an issue for me for all the tld descriptors (11, 12, el) with
jrun4.

The <example> elements ARE valid according to the sun dtd.
All the dtds (1.1, 1.2, 1.2 EL) validates correctly.
Maybe there was an error (in the element order) in the past?
I'm closing this bug, since EL support has never been released
and appears to be working now.
