I think you need to modify your code just a little. I assume that your
META-INF/hk2-locator/default files are present in your application
archive. If that is so then you might want to try giving the
classloader to the populate call like this:
try {
populator.populate(new
ClasspathDescriptorFileFinder(getClass().getClassLoader());
} catch (IOException e) {
throw new MultiException(e);
}
This uses this:
https://hk2.java.net/2.2.0/apidocs/org/glassfish/hk2/utilities/ClasspathDescriptorFileFinder.html
This assumes that a getResources call on that classloader will find the
META-INF/hk2-locator/default files that are in your archive.
Hope this helps,
