Use of @Parameters in WELD-SE,

[kalber]

1. starting the container and passing something as arg.

public class Bootstrapping {

     public static void main(String[] args) {

        Weld weld = new Weld();

        try (WeldContainer container = weld.initialize()) {

        }

}

2. Inject @Paramters in my HelloWorld, but  is null.

@ApplicationScoped

public class HelloWorld {

    @Inject

    @Parameters

    List<String> params;

    public void printHello(@Observes ContainerInitialized event) {

        System.out.println(String.format("Hello i have %d args", params.size));

    }

}

My question is, is @Parameters referring to args ?

Or @Parameters a readed from a config.xml file ?

Hi Karlheinz,

yes, parameters refer to command line arguments. However, they are available out of the box only if org.jboss.weld.environment.se.StartMain is used. So if usig a custom main method you'll have to set the args manually, see also org.jboss.weld.environment.se.beans.ParametersFactory.setArgs(String[])
