I’m not a Windows user, nor a J\*\*\* user, not even a Netbeans user, but it seems like Netbeans is trying to execute “cmd” to get a DOS console. Try to open it your self and install the gem via the gem command. Hope it helps. – Leonardo M… There’s no place like ~ ---

You probably want the `jdbc-mysql` and (if you’re using Rails) the activerecord-jdbcmysql-adapter gem(s) instead. ## HTH, Hassan S. ------------------------ removed\_email\_address@domain.invalid twitter: @hassan ---

Deva, any luck with this issue? Having the exact same problem when I upgraded to Netbeans 6.7.1 on Windows XP.
