Re: How to configure DODS_HOME

Hi Juan,

What version of BarracudaDiscRack are you using? It should work with no 
modifications at all.  Just use ant to generate the .war file and deploy 
that to Tomcat.  It should just work.  All the Dods stuff is pre-generated 
and set to use.

Note that if you are trying to compile against newer Dods and such, things 
might not work.  The Dods stuff that BarracudaDiscRack uses depends on the 
version in Enhydra3.1.1beta (which BaracudaDiscRack includes as a stripped 
down  jar file in WEB-INF/lib).  There hasn't been, nor will there be (at 
least by me) any attempt to bring this up to date with the latest Dods 
stuff.  I just don't use it.  I have verified that everything works under 
Tomcat versions 4.1.xx and 5.0.xx.  If you are running this under Enhydra 
5.1, you might ask those guys how to get it to run(I'm not even sure 
they've verified it?).  My expertise is in Barracuda and XMLC, but not 
Enhydra (haven't used it in a long time).

Can anyone else provide any help here?
