[Bluej-discuss] netbeans

[Jobling C.P.]

I think you may be better off opening the BlueJ project in netbeans rather
than copy and paste from BlueJ code editor. There's nothing special about a
BlueJ project apart from a couple of extra files that it keeps for the
purposes of class diagram layout and the user interface components. It's
just a folder. Netbeans also uses a folder as the container for a project:
it will only care about the *.java files and will ignore the *.ctxt files
and the BlueJ project file. 

I don't have a copy of Netbeans to hand, but I imagine that there is an
"import" option in the new project menu (or somewhere) that will allow you
to pull the contents of a BlueJ project (which will be a folder) into a
netbeans project. (This may produce a copy of the original project)

Furthermore, if you're using Netbeans 5 BlueJ Edition it is designed to open
a BlueJ project directly (here's a quote from the page at
http://www.bluej.org/netbeans/tutorial/index.html:

  "NetBeans IDE 5.0 BlueJ Edition is a variant of standard NetBeans, with
two significant differences:

    * It can open, work with and create BlueJ projects.
    * The standard NetBeans interface has been simplified.") so there's
probably a menu item that allows you to open a BlueJ project. 

In fact the documentation states that Netbeans 5 BlueJ Edition uses the same
folder, so you can switch back an forth between Netbeans and BlueJ!

If you have any libraries in your BlueJ project (e.g. external *.jar files),
they will have to be attached to your netbeans project's "classpath" as
project properties. Again, Netbeans BlueJ Edition may pick up the
information it needs from the BlueJ project file and BlueJ preferences to do
this for you automatically.

Hope this helps.
