Running Ready2Run Jetty+OpenBD on a Mac
When trying to run OpenBD on my mac, I was getting this error “java.lang.UnsupportedClassVersionError: Bad version number in .class file”:
To fix this, fallow these steps:
From the Apple () menu, choose Software Update.

Software Update checks for available updates. In the Software Update window, select the items you want to install, then click Install. Usually, you should install all available updates.
Enter an administrator account name and password.
After installation is complete, restart the computer if required.
The error should be fix, if you are still having issue, please leave a comment with the error.

I have tried your suggestion, but I do not have any updates available. I am trying to run on a 10.4 Mac Mini. Any other thoughts?
Is OpenBD your only option? I suggest looking at Railo as I use it more now than Adobe CF and OpenBD.
