Console missing: JBuilder 8?

I have written a front end gui in JAVA that launches two C++ console
applications. When launched from within JBuilder 8 the console application
output goes to a pane internal to JBuilder 8 and I see that it is correct.
When launched via a desktop shortcut to the .JAR file no console window is
launched (for System.out.println calls reporting each Process'
outputstream). The Process' errorstreams are empty. JBuilder 4 (the previous
IDE for this project) automatically launched a console window when the .JAR
application was launched. Why don't I see a console now? Is this a problem
with JBuilder 8?

Assuming that you are using Windows, it is likely that the shortcut is
configured to run javaw.exe and not java.exe. Since javaw.exe is a
non-console application (sorry for the Windows-speak), there is no
console window for the child processes to inherit. Depending on how
exactly Runtime.exec() is implemented, you will see problems. Try
running the jar from the command line with java.exe and see if it works.
