I have some problem, I hope somebody can help me.

Currently, I'm using Power Builder to created my application. But the
latest version of Power Builder can not support Sun Solaris, and all
my clients are using Sun Solaris for Server and Workstation.

Now I plant to using InterBase or Firebird as a Database Server, but
I still can not fine any development tools which support Sun Solaris
and InterBase or Firebird Database.

Do you have any recommend, which development tools meet my
requirement?

Thanks,
