Tapestry Exentsions (ITemplateSourceDelegate)
Following Erik's suggestion, I'm trying to create an extension for my
application that implements ITemplateSourceDelegate. My .application file
contains the following:
<application name="DSH">
<extension class="dsh.BorderDelegate"
name="org.apache.tapestry.template-source-delegate" immediate="yes"/>
<library id="contrib"
specification-path="/org/apache/tapestry/contrib/Contrib.library"/>
</application>
Unfortunately, the "dsh.BorderDelegate" class never loads.
While debugging, I noticed that in DefaultTemplateSource.java, the call to
"if (spec.checkExtension(Tapestry.TEMPLATE_SOURCE_DELEGATE_EXTENSION_NAME))"
(line 228) returns false, which to me indicates it never properly read in
the extension entry in the .application file.
The called function ends up in LibrarySpecification.java, which makes me
wonder if all my code must be wrapped in a <library-specification>, though
the docs indicate otherwise.
I'm probably missing something simple, but as I haven't been able to find
any examples of extensions, I'm slightly stuck at the moment.
Thanks,
Chris

You nailed it. A couple of weeks ago I had a problem getting the
Examples.library to load. I didn't pursue at the time.
Despite declaring the contrib library, I hadn't used it yet. I just now
tried it and got the same error. Double-checked my web.xml file and the
servlet names didn't match what I had been expecting.
Sheesh.
Thanks for the wake up call. I shall keep plugging along now that I the
extension is loading.
Now the fun can begin!

With immediate=yes it should not wait until the template source requests it. Anything odd on
startup? Are you ABSOLUTELY sure that Tapestry is pickup up the right .applilcation file? You might
want to enable some debug output.
