The below description from the spec says that resources inside the
META-INF/resources directory of JAR files might be consider only if the
container has unpacked them.
Since the getRealPath is used to return a virtual path, when will the
unpackaged location of resources directory be considered ? Only when the war
package is not unpacked, but the META-INF/resources directory are extracted
?
Thanks !

Resources inside the META-INF/resources directory of JAR file must be
considered only if the container has unpacked them from their containing JAR
file
when a call to getRealPath() is made, and in this case MUST return the
unpacked
location.
