VariableDeclarationFragment node resolveBindind() returns null in eclipse/jdt/ast

Question

I\'m trying to try out eclipse jdt/ast following this article.

This is the java code as an input:

class Hello
{
    int hello()
    {
        int a =         


        

Answer 1

Does this mean I have to import source codes I want to run ASTParser on in my current project?

Right now I am using ASTParser incoporating with UIMA framework. In that framework, I could get source code in char[] only. Don't know how to get their corresponding IJavaProject and UnitName, which is needed if I .setSource() to a char[].
