Subject RE: [OT] getting name of launch jar

Just seems cleaner to me that's all. I'm there are cases where both methods
break down anyhow (make your own class on the fly with BCEL and load it).

--DD

PS: You still assume the class is coming from a JAR. I'd have to check
myClassURL to see if it's file: based, http: based, jar: based, etc... And
you'd have to deal with inner classes in a.B$C, etc... It gets complex.

Indeed. That wasn't an issue for our particular case. The following may 
work for those situations:

String className = MyClass.class.getName();
URL myClassUrl = MyClass.class.getResource("/" + className.replace('.', 
'/') + ".class");
URL jarUrl = 
((JarURLConnection)myClassUrl.openConnection()).getJarFileURL();

I think.

Why not? What recommends the getProtectionDomain method over this one?

Ciao,
