Thread: Environment independent single .war generation

Hi All,

I have a project which has a set of configuration files, where each configuration file represents an environment specific configurations. In other words, I have 3 environments, development, staging, and production. The configuration for each environment is different, e.g. DB name, url etc.

Whenever I want to deploy the same code, on each environment, I have to manually generate environment specific .war file, so that it has environment specific configuration file in it.

What I am looking for is a kind of solution where i have to compile only once in maven and it generates only one .war file, which I can use on every environment. In other words, i want the environment specifi application server/tomcat to identify which configuration to pick.

That way, I'll be sure that we are deploying and testing the same .war file on every environment/application server.

How can i restructure the application to achieve this functionality?

Thanks.

If so, how would the configurations be included? Would it be like one large configuration file which includes all 3 environment configurations or something, and you want the specific environment configuration chosen at runtime?

Thanks for replying, aussiemcgr.

I would like to keep three configuration files in the single jar, but would want each application server to pick the correct one somehow.

Or maybe takeout the configuration files out from my source folder and make each configuration file part of specific application server.

Or there could be any other solution that fits my requirement, i.e. one .war file to be deployed on all the servers.

If I keep a single big configuration file and replicate the parameters but with different environment specific values then it is not a very elegant solution in my opinion.

The requirement is when i do a dev testing using a .war, i want that same .war to go onto the staging and production. Right now it is not the case, the dev testing is done on one .war and another .war is generated and put on staging, similarly another .war on production system. I want to improve this workflow and make sure we are usign the same .war on production system that we deployed on dev and tested on staging.

thanks.
