wireless tookit, can´t build project

[brazz]

I have problems in building a project with the Ktoobar feature in
the J2ME Wirelless tookit.
I start a new project nicely, I then put my MIDP code in the /apps/src directory like I´m supose to.I hit Build and I get the erro message "Build Failed", in the console appears the
following:

Project "hellomidlet" loaded
Project settings saved
Building "hellomidlet"
No sources to compile
Build failed

I´m following the Device Programming: MiDP for Palm tutorial from

SUN, this is the link
