I am using JBuilder 8 SE, MobileSet 3.0.1, and Series 60 MIDP Concept 0.3 Nokia edition, downloaded from Nokia Forum. I'm using JDK 1.4.1 under WinXP.

To verify my installation, I have tried to create the HelloEx MIDlet described in the 'Creating MIDlets v1.2' document (and configuring JBuilder according to this document). I can without any problems build HelloEx, but when I try to 'Create Application Package', I run into problems. Upon pressing 'Generate' (and designating where jar and jad files should go), I get a window with
Unable to create Application Package
java.io.FileNotFoundException: C:\Nokia\projects\Hello_Project\preverified-temp\Hello_Project\HelloEx.class (The system cannot find the path specified)

To me this suggests that there must be a misconfiguration somewhere, but I would sure like some suggestions where it might be.
