When using the projects from the german version of the book:
JAVA lernen mit BlueJ (4. Auflage) i got the following problem.
BlueJ could not read Chapters and their subfolders when i leave the folder name with a minus character in the name as it is delivered.
Once i modified this ( replace the minus by nothing )BlueJ can read the folders and the subfolders with the resources where recognized.
In chapter 3 the folder Mail-System/MailSystem is not recognized even if i try to rename it.
I didn?t perform further negativ tests replacing the minus by other special characters.
When i start browsing in any of the folders containing the resource files by double clicking a package file BlueJ opens everything and i can recompile my files.
I use JAVA 1.6.0_18 JRE and a Window XP SP3 on a Dell 4300 Workstation (Laptop).
Many thanks for your help/advise
