[appengine-java] Re: Is there a recommended way to differentiate between production and dev GAE environments?
I found this in the Programming GAE book by Dan Sanderson, O'Reilly, 2010: An app can determine whether it is running on AppEngine or in the development server from the servlet info string in the srvlet context, returned by this.getServletContext()getServletInfo(). This string starts with Google App Engine Development when running in the development server...

Re: [appengine-java] Re: Is there a recommended way to differentiate between production and dev GAE environments?
Hi all,
App Engine officially supports a way to differentiate
between production and development as follows:
String env = System.getProperty(com.google.appengine.runtime.environment);
if (Development.equals(env)) {
...
} else if (Production.equals(env)) {
...
}
See http://code.google.com/p/googleappengine/wiki/SdkForJavaReleaseNotes
Hope this helps,
Yasuo Higa

[appengine-java] Re: Is there a recommended way to differentiate between production and dev GAE environments?
My approach is quite simpler. I keep a configuration file where I
setup a different webBaseURL depending on the environment, development
VS production. One could a a boolean isProduction and make webBaseURL
a function of that. The thing to remember is to setup the config file
before uploading to GAE and then resetting it back to the development
config.
public class Config {
// True or false the UI actions (buttons) and the http servicce
requests
// are logged.
private static boolean isLogOn = true;
// Web base URL
/private static String webBaseURL = http://
wcondominios.appspot.com/;
private static String webBaseURL = http://localhost:8080/;;
/**
* @return True or false the the UI actions (buttons) and the http
* servicce requests are logged.
*/
public static boolean isLogOn() {return isLogOn;}
/**
* @return The Web base URL
*/
public static String getWebBaseURL() {return webBaseURL;}
}
