    Default How to load binary content of a .class file

    when given the name of a class, I want to retrieve the binary content of the .class file. I have written the following sample but it does not work.
    Can anyone help to find what is wrong with my sample?

    Java Code:
    String className = this.getClass().getName();
    InputStream inputStream = this.getClass().getResourceAsStream (className);

    When executing the above code, the input Stream is always returned as "null".

    The name of the file containing the bytecode is not the same as the classname, but it has a suffix ".class". Furthermore, a classname as returned by Class.getName() returns the fully qualified name, including the package, with "." as the separation between the parts. That will probably not be a valid filename (I can think only of z/OS as an OS that uses the period as a separator char), since you're looking for that file on the filesystem. Replace the "." with the File.separator string and you should be set.
