Question

I have Java function:

public String getEnvironment(){
    String env =  System.getProperty("tomcat.runtime.environment.version");
    if(env == null)
        return "DEV";
    return  env;
}

and it is usually called this way:

string devEmail = configuration.getString(getEnvironment() + ".DEVELOPER_EMAIL");

Basically, getEnvironment will return strings (depending of environment) DEV, TEST or PROD and it will read from some configuration object proper information for current environment.

The part I don’t understand is how is this set? How production server knows to return PROD, developemnt DEV, or test server to return TEST? Or, how do I set property “tomcat.runtime.environment.version” on the web server?

It’s Apache Tomcat 6.0 web server.

Answer 1

you need to add it to catalina.sh on linux or catalina.bat on windows.

JAVA_OPTS="$JAVA_OPTS -Dtomcat.runtime.environment.version=PROD"
