tomcat7上的Java命令行参数

Question

We have a grizzly-jersey application whose main() takes java command line args(org.kohsuke.args4j) and fed into a class called Features.java which looked something like below

@Option(name = "--enableAuthentication", usage = "--enableAuthentication=true/false")
private static String  enableAuthentication = Boolean.TRUE.toString();

we used to deploy the web application as JAR.

Now we moved to WAR model, and we are using tomcat7 as the servlet container.
- how do I pass those cmd line args INTO this application
- how do I access those cmd line args IN the application

Environment
jersey 2.9 + spring
tomcat 7.0.46
java8
ubuntu 12.04
maven

Answer 1

in tomcat 7, under bin directory create set setenv.sh file

add following line

-D--enableAuthentication=true/false

This should work.
