Hi David,
The command line I use is
D:\cosmos-demo\bin>configDemo c:\Program Files\Apache Software
Foundation\Tomcat 5.5 d:\cosmos-demo d:\birt-runtime-2_3_0.zip
I'm guessing there is sensitivity to the spaces in the file names. Try
putting double quotes around each argument. Let me know if that's not
the problem, and I'll look at the source code for the demo runner.
