Enhydra 5.1.7 and Barracuda 1.2

Hi,

I'm trying to run Barracuda 1.2 tutorials in Enhydra 5.1.7 but I can't make
them work. If I'm connected to the internet, some examples work fine but
Barracuda Config doesn't work. If I'm disconnected from the net, I get error
404 file not found for all the examples (I've checked the URL and I'm using
http://localhost/Barracuda). Any idea about this?

Also I want to check if Enhydra 5.1.7 is still using Tomcat 3.0. Is that
right? If the answer is yes, can I use Tomcat 4.1.24? Can anybody send me
the required steps or guide me for this.

Thanks,
Darío
