Thank you for your answer.
Could anyone give any suggestion about the following?
I have my named module and weld-se-shaded as unnamed module.
In my module I have
module my.module {
requires weld.se.shaded;
exports com.foo;
}
#################################
package com.foo;
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;
@ApplicationScoped
public class NewClass {
@Inject
private NewBean bean;
public void doIt() {
bean.doIt();
}
}
#################################
package com.foo;
import javax.enterprise.context.Dependent;
@Dependent
public class NewBean {
public void doIt() {
System.out.println("I am doing it);
}
}
And this is the result
