Subject Re: Virtual host deployment
Date Tue, 14 Sep 2010 21:52:50 GMT
Hi Chris,

Thank you for the defaultHost recommendation.

The deployment scenario I would like to support requires deploying the same
WAR file on the development server first and then on the production server.
Development and production servers use different database credentials, so I
cannot package them in the WAR file itself. So, the database credentials
should be stored somewhere in the server configuration.

What is the recommended way to support  this scenario? Is there any other
place besides conf/context.xml where I can store server-specific DB
credentials?

Thanks,

Alec
