How to get a resource from a specific jar

I have a few jars which contain some resources with the same name. Lets say I have a.jar and b.jar and they both contain resource.xml. I know I can get a resource calling 

getClass().getClassLoader().getResourceAsStream("resource.xml");

But AFAIK it may return a resource either from a.jar or b.jar. I want to pass the jar file name and get the resources from the specified jar.

Make sure that a.jar is before b.jar on the classpath.

If you cannot guarantee that you can do something like this

    ...
    Enumeration<URL> urls = getClass().getClassLoader().getResources("resource.xml");
    while(urls.hasMoreElements()) {
        URL url = urls.nextElement();
        if (url.getPath().contains("/a.jar")) {
            return url;
        }
    }
    return null;

If they are in different packages (check your jars manifest) you can use packagename to access R class.

As an example:

getResources().getString(<com.mycompany.mypackage>.R.string.yourstring)
