On Linux, the required distribution for Java Studio Creator 2 (now Free for all SDN members) is Fedora. I’m a Debian user and I succeeded to install it, however.
The first time my installation completes too soon, without correctly installing Java Application Server. I read the FAQs and I found a page saying:
Check if the following RPM packages exist on your system:

• either libstdc++ or compat-libstdc++
• either libstdc++-devel or compat-libstdc++-devel

The correct Debian (Etch) packages (apt-get ‘em!) are

• libstdc++2.10-glibc2.2 and
• libstdc++2.10-dev

I don’t know if both are required or only the first one, but now the whole installation of Java Studio Creator 2 is complete.

Thanks to David Coldrick’s Weblog (installation on Ubuntu of JSCreator 1).
