I’ve never used this product before so I’m not sure exactly what to expect. Community edition seemed to install OK on Mac OS X 10.3, although it wasn’t automatically launched. No startup shell script was installed, so I just ran the vpuml.jar. It presents a working configuration UI, but when I click the Finish button that’s the end of the story – the config window goes away and nothing else happens. There’s nothing bad in the system console.
