How to read a file inside a jar's resources from ouside the jar

Question

I have a file X.json inside abc.jar in its classpath. There is a method readFile in abc.jar which reads the file as

URL url = Abc.class.getClassLoader().getResou         


        

Answer 1

By the time of deployment, those resources will become an embedded-resource. That being the case, the resource must be accessed by URL instead of File. See the info page for the tag, for a way to form an URL.
