Reading my own Jar's Manifest

Asked 2009-08-13T15:17:04.393

I need to read the Manifest file, which delivered my class, but when I use:

getClass().getClassLoader().getResources(...)

I get the MANIFEST from the first .jar loaded into the Java Runtime.
My app will be running from an applet or a webstart,
so I will not have access to my own .jar file, I guess.

I actually want to read the Export-package attribute from the .jar which started the Felix OSGi, so I can expose those packages to Felix. Any ideas?

java osgi manifest.mf apache-felix

You can use getProtectionDomain().getCodeSource() like this :

URL url = Menu.class.getProtectionDomain().getCodeSource().getLocation();
File file = DataUtilities.urlToFile(url);
JarFile jar = null;
try {
    jar = new JarFile(file);
    Manifest manifest = jar.getManifest();
    Attributes attributes = manifest.getMainAttributes();
    return attributes.getValue("Built-By");
} finally {
    jar.close();
}
