Yeeha!
That did it for me as well - have to look now see exactly what that does with
the jar.
Thanks a lot folks
This is starting to sound like an issue that should be fixed in tapestry
rather than changing the way the jar is generated.
It sounds like tapestry will act differently when referencing a classpath
jar than if unzipping the jar and referencing a classpath directory. I think
tapestry should act
Hi,
Not sure if this will help you, but I had the same problem when exporting my
jar from eclipse.
Checking the Add directory entries option in the JAR export solved it for me!
Best regards,

Interesting...
I had to change findResources to getResource as findResources isn't publicly
visible, but it dumped this :
jar:file:/C:/Development/Projects/Test-Tapestry-Module/MyPlugin.jar!/org/test/pages/TestPage.class
Also, the classLoader here is an instance of
org.apache.tapestry5.internal.plastic.PlasticClassLoader which obviously
contains the module pages, whereas the one in the ClassNameLocator
implementation is looking at one called ContextLoader@TestApp (where TestApp
is the name in the web.xml).

Can you try getResources() instead of getResource()

Yeah - that just returns an Enumeration of URLs for each call.
Each Enumeration has one entry, so
jar:file:/C:/Development/Projects/Test-Tapestry-Module/MyPlugin.jar!/org/test/pages/TestPage.class
for the class, and

Yes, with the added bonus that duplicate locations on the classpath will be
exposed
I'm baffled... I have no idea why this would work for the upload library but
not yours... What container are you using?

This might be caused by the location of your jar file
C:/Development/Projects/Test-Tapestry-Module
Where is the tapestry-upload.jar located? Is it inside a WAR?

In a webapp, there is a hierarchy of classloaders with the web classloader
inheriting from the application classloader which in turn inherits from
the bootstrap classloader. Tapestry adds another classloader to the mix to
confuse things further. I think something is going on with your classloader
This is with 5.3.3 by the way.

Please copy/paste the following:
1. Your contributeComponentClassResolver() method
2. The fully qualified classname of one of your components.
3. A TML entry where you are trying to reference one of your components

OK,
The library contains a page rather than a component (although a component
copied in from teh tapestry upload library didn't work either...)
If I try reference it from the main app, all I get is this :
I would also expect the library pages to show on the list of available pages

A page is a component ;)
Have you included a Tapestry-Module-Classes entry in your jar's manifest?

Yep.

Is there anything strange with your classpath?
eg. multiple copies of the tapestry jars or multiple copies of your Page
class / template?

Have you contributed to the ComponentClassResolver in your TestModule :-
public static void contributeComponentClassResolver(
ConfigurationLibraryMapping configuration) {
configuration.add(new LibraryMapping(mylib, org.test));
}

Strange, can you add the following to one of your pages/components in the
