Find the location of your classfile

There are many reasons for tring to find what location your java class is loaded from. E.g a big jee server with many apps and conflicting versions of libraries (read: a mastodont of a Websphere server)...

Here is the code that has saved many a day for me:

	private String getPath(Class cls) {
	String cn = cls.getName();
	String rn = cn.replace('.', '/') + ".class";
	String path = getClass().getClassLoader().getResource(rn).getPath();
	int ix = path.indexOf("!");
	if(ix >= 0) {
	return path.substring(0, ix);
	} else {
	return path;
	}
	}
