Hi,Prof. Barnes and friends,
I use java.lang.reflection to get class inheritance and methods for java
file.
I used before (in AWT) it works: you can check this link:

http://www.ecs.csun.edu/~jackie/Meta.html
Now I use it in a Swing application, I got error: Class not found(it shoud
be there) and nullPointerException.
Please take a look the attached file.
