Newbie: cannot find method

Hi everyone, this is my first post. I've been learning Cocoa for
awhile, and I've started my first app that I intend to complete to a
polished state. Introductions aside, my problem (which probably has a
simple answer) is as follows:
I have a method within a controller class, from which I try to call
another method, declared within the same header file, and defined
within the same code, using [self theOtherMethodName];
I get a compiler error, saying that the method cannot be found. Here
are some code fragments with added comments:

//as they appear in the header file of the class:
- (IBAction)JDAProcess:(id)sender;
- (IBAction)JDAWriteOut:(id)sender;

//in the code, the second method tries to call the first one using:
[self JDAProcess];

Additional note, the methods are defined one after the other in the
code, as they are in the header.

So, any help with this would be appreciated, I am new to OOP in
general. Thanks!
