Seth,

Thanks for the response.

I did figure out the data bag item issue shortly after...at which point I 
tried to create a node and manually specify fqdn and ip address, since it's 
SQL Server, production, and not ready to install chef on quite yet. ;)

At that point, when I tried updating the client definition...I killed my 
server. The node list never returned. It could be I tried editing it in the 
Web UI between exporting the client as json and re-importing it...

So I learned a lesson: Don't mess with nodes manually, LOL. What should I do 
in this situation? Is installing the Chef client the only way around it, or 
should I modify the recipe to take an override from json?

I'm going to look at the mods made by Haselwanter Edmund to see if that gets 
me what I need.

-Matt

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.
