Actually, you shouldn't even need to read the content of the class file. The
class file name itself contains a hash of the original file name. Matt
Liotta posted this to another list recently:
"The below Java class should get you pretty close. I know of one special
case where it won't work, but the name will be close enough not to
matter.
import java.io.*;
public class FileUtil {
public static void main(String[] args) {
System.out.println(findClass(args[0]));
}
public static String findClass(String path) {
File file = new File(path);
String name = file.getName();
StringBuffer buf = new StringBuffer(name.length() + 20);
String className = "cf" + name.substring(0,
name.length()-4) + "2e" + name.substring(name.length()-3);
int code = file.hashCode();
if(code < 0)
code = ~code;
return className + code + ".class";
}
}"
I compiled it, and it worked fine. Just feed it the fully-qualified file
path and name as an argument. Thanks go to Matt for that.
