How to programmatically read the attributes of a JAD file before 4.3.0

[ushernut]

I need to read the modified jad file's description into program after it is built.
I have tried the way that knowledge base mentioned, which is adding the .jad file to project, and it will be able to be read.
But the problem is also like knowledge base said, once it is built, jad file cannot be modified, even you did that, it will not be read again.
Does anyone realize this on 4.2.0?
