Matt,
The context.xml should have been created as 
"/srv/spark_server/shared/AppName.xml" [0], but that will only happen if a 
database master is found in the search [1]. This file is then symlinked over 
[2] into the tomcat context dir. It appears you are missing the 
'database_master_role' value in your data bag item, this would cause the 
search to return no results.

Right now the application::java_webapp recipe only supports deploying wars 
into the root of the container. Mostly because in our initial customer use 
cases they were deploying single apps into smaller horizontally scaled app 
servers. Deploying into the root context makes automating the configuration 
of the load balancing layer much easier.
