I've spent a few hours reading the Jersey embedded GF container source, as well as source for ScatteredArchive from the 3.0-Prelude-Embedded-b14 build (wow, that was not easy to find) of embedded GF.
I'm sure I'm missing something but on the console when I run tests I see
Sep 4, 2010 6:50:32 AM com.sun.jersey.api.core.WebAppResourceConfig init
INFO: Scanning for root resource and provider classes in the Web app resource paths:
/WEB-INF/lib
/WEB-INF/classes
Sep 4, 2010 6:50:32 AM com.sun.jersey.server.impl.application.WebApplicationImpl _initiate
INFO: Initiating Jersey application, version 'Jersey: 1.4-ea06 08/27/2010 02:42 PM'
...
[further down Jersey says it cannot find any resource classes --- same as stack trace below]
but in the Jersey embedded GF container source, I see ScatteredArchive in createArchive() assembling a war using
war = new ScatteredArchive(baseUri.getRawPath(),
new File(SRC_WEBAPP_PATH),
new File(SRC_WEBAPP_PATH + "/" + WEB_INF_PATH + "/" + WEB_XML),
Collections.singleton(new File(TARGET_CLASSES_PATH).toURI().toURL()));
where TARGET_CLASSES_PATH is hardcoded in the Jersey embedded GF container instance as "target/classes".
If you look at how maven generates this target/classes directory, you find that there is no target/classes/WEB-INF directory, which is what Jersey appears to be scanning on startup. The maven war plugin is the thing that builds targets/<appname>/WEB-INF, not the compiler plugin. And the war plugin does not run in the test phase.
This has to be a one-line fix somewhere, but at this point I'm stumped.
Anybody?
