[THREDDS #CZR-333353]: running multiple TDS' under same tomcat



Hi Kevin,

It isn't clear to me from the error messages what the problem is when you run 
two TDS on the same Tomcat instance. We have not introduced a new way to 
accomplish this. I will dig into it and see what I can figure out. I'll get 
back to you soon.

> </context-param>
