Projects
●
●
We always work in projects (NetBeans will
create a project)
A Project uses a project directory (use
suffix .nbp (netbeans project) i.e. myproj.nbp)
–
Project has (default) same name as the dir
–
Project dir contains
CHALMERS
●
●
●
●
Netbeans config files; build instructions, library
inclusions,dependencies,...
Source code, test code
Application config files
Possible other files, XML, XHTML, Javascript, CSS,...

●
The project directory has a fixed (sub) directory
layout

Projects tab

Many dirs and files

project, the
components and files
we normally need.

Files tab
