Re: how to execute a class as an external Java application

your code helps me a lot, however, in my opinion it doesn't work,
moreover, it won't compile :) I think you just wrote it without
checking it.
The first, you meant probably:
String path = cls.getClassLoader().getResource(rn).getPath();
It was tested, but:
String path = GetPath.class.getClassLoader().getResource(rn).getPath();
assumed the code was in a class GetPath.
The second, I don't have the faintest idea why are you serching for
"!", maybe you intended to search for "/" ?
Because classes in jar files are named:
jar URL!path to class
Another problem is that the function returns the path to the directory
containing the class file, which is wrong, in my opinion, if a class
is a part of a package. In that case, I think, it's necessary to
invoke this class with a "fully qualified name" and the appropriate
directory specified. And the appropriate directory in this case is the
one containing the package directory, not the class file.
For your usage you would need to convert the path to class
to the app classpath by stripping of the package path.
