Every once in a while on running an application via JDev, usually just before I'm about to present (argh!), the integrated WLS doesn't start, displaying the following error message:
*** Using port 7101 ***
[waiting for the server to complete its initialization...]
\QuickTime\QTSystem\QTJava.zip was unexpected at this time.
This error occurs because under Windows, anytime I update Apple's iTunes on my PC, which in turn more often than not installs a new version of Apple QuickTime, the QuickTime installer adds the following entry to the CLASSPATH environment variable:
CLASSPATH=.;C:\Program Files (x86)\QuickTime\QTSystem\QTJava.zip
It can be fixed by removing the entry, and restarting JDev.
