I'm using the name consistently - the name was resolvable when in core.
I tried to generalize the description of the problem in the email, but
forgot to rename the TagLibrary impl class to from IconsTaglib to
MyFunkyTaglib. Sorry about that... should have just left as is :)

I suspect one thing could be that your class name is IconsTaglib and
not IconsTagLib

Well I suspect that you need to inform jelly of the TagLibrary
class or else it will not discover it. I am suspecting that there
is a plugin goal putting the requisite info somewhere on the
classpath. That plugin goal is probably working for jenkins core
but perhaps not by default in plugins

xmlns:myf="jelly:org.jenkins.x.y.MyFunkyTag" is one way of
doing that and, as I said, that works when the TagLibrary impl
is located in Jenkins core (Vs out in a plugin). I didn't see
any other way of doing it. Are you telling me there is
another way?

Hi.
Just wondering if anyone can guide me as to how I can
write a Java based TagLibrary and have it loadable from a
plugin (without setting pluginFirstClassLoader=true).
When I try it I get a classloader exception that makes
total sense to me, but I'm wondering if there's some
trick or different impl that works around it.
Example... a Simple TagLibrary impl like this...
public class IconsTaglib extends TagLibrary {
public IconsTaglib() {
// Register some tags...
registerTag("*myFunkyTag*", MyFunkyTag.class);
}
}
This class is located in the plugin i.e. not in Jenkins
core with other taglibs.
Then in a .jelly tag script (also in the plugin, but for
which there are no cloassloading issues) we use the
*myFunkyTag *tag that was implemented in Java e.g.
<myf:myFunkyTag
xmlns:myf="jelly:org.jenkins.x.y.MyFunkyTag" />
The above causes a ClassLoading exception because Jelly's
XMLParser class (code located in Jenkins - not in the
plugin) tries to load the MyFunkyTag class with the wrong
classloader (XMLParser line #1024). What looks like
would work (in this specific case at least) is if
XMLParser tried using the JellyContext ClassLoader
instead, but of course that might cause other issues.
BTW I tried with the MyFunkyTag impl located in Jenkins
core and everything works fine as expected.
Any suggestions? I'm wondering maybe this is not an
issue if I implement the Tag in Groovy instead, but would
like to know if doing it in Java is not going to work first.
Thanks,
Tom.
