It is very simple: just use a VoidVisitorAdapter and ovveride this method:

public void visit(final FieldDeclaration n, final A arg)

In this way you can access all fields. You just need to call getModifiers to verify the field has the static declaration.

To get the line just call getBeginLine on the FieldDeclaration.
