Re: How can I determine if user is running locally?

This is what we do:
We require that there be NO changes to a given ".ear" file from one envirnment to the next.
We set a '-DConfig.env=xxx' on the jvm command line, where xxx = 'dev', 'test', 'qa', or 'prod'.
Our developers then load Properties files appropriate to the environment they are running in.
If you bundle your properties files in your WEB-INF/classes directory such as:
WEB-INF/classes/props/test/appenv.properties
WEB-INF/classes/props/qa/appenv.properties
WEB-INF/classes/props/prod/appenv.properties

you can load the appropriate properties via something like:

Properties prop = new(Properties);
String env = System.getProperty("Config.env");
/* build "file name" for properties file */
String filename = "props/" + env + "/appenv.properties";
/* use the current web application's class loader to locate and open the properties file */
InputStream propStream = Thread.currentThread().getContextClassloader().getSystemReasourceAsStream(filename); 
prop.load(propStream);
propStream.close();


(add exception handling as appropriate)
