Just wondering: Did you try IcedTea without Jandex?
Yes, but I found the problem, DefaultBeanArchiveScanner is using com.sun
APIs in order to get the cached JAR path,
com.sun.jnlp.JNLPClassLoader#getCacheFile(URL). Since NetX does not
implement that method the mapping from http[s] URL to local file is not
done, this is why the archive handler was getting the remote URL.
Doing reflection, but using icedtea-web code structure, with this way of
getting the path works:
if
(jnlpClClass.getName().equals("net.sourceforge.jnlp.runtime.JNLPClassLoader"))
{
// Try to get field net.sourceforge.jnlp.runtime.JNLPClassLoader#tracker from
icedtea-web 1.5
Field f = jnlpClassLoader.getClass().getDeclaredField("tracker");
f.setAccessible(true);
Object tracker = f.get(jnlpClassLoader);
// Try to call net.sourceforge.jnlp.cache.ResourceTracker#getCacheFile(URL)
Method m = tracker.getClass().getMethod("getCacheFile", URL.class);
File jarFile = (File) m.invoke(tracker, new URL(path));
return jarFile.getPath();
} else {
// ... current code
}
Too bad that it is not only a public method call, there is an access to
a private field (tracker).
The icedtea-web 1.5 branch repository history show this field and method
call to have been stable at least since 2010 when the icedtea-web 1.5
repository was created, and master haven't changed. I can bet to use
this patch on my deployments since there is already usage of reflection
to get the URL on closed source WebStart, it this too hacky for beint
committed to Weld?

That's very suspicious. Assuming there are no @EJB injection points in
your application this service should not be called at all. Wasn't it
EjbServices instead?

True, I added a test @EJB injection, isn't EjbInjectionServices the one
I should implement in order to inject my remote EJB interfaces? or
should I implements EJBServices instead?
I used it because of the warning on the documentation:
EJBInjectionServices.resolveEjb(InjectionPoint ij), which allows @EJB
injection point to be resolved without prior registration was deprecated
in Weld 2 and should no longer be used. An injection point should be
registered properly using
EjbInjectionServices.registerEjbInjectionPoint(InjectionPoint
injectionPoint) instead.
