Hi,

BeanProvider just works for managed beans as it just "provide beans" from the 
underlying CDI container.

If you would like to do injection in a unmanaged object, you can do the 
following:

MyUnmanagedBean a = new MyUnmanagedBean();
BeanProvider.injectFields(a);

Thomas

Hello,The BeanProvider makes me confused for a few days. Could anyone help me 
out?The problem in my case is that I cannot get an instance of a non-managed 
class by BeanProvider.getContextualReference() method.I listed my case as 
following:

// DeltaSpike 1.4.2, Weld 1.1.31, CDI 1.0-SP4

//--Class A--public class A {    //member fields

    private B b;    //Constructor with parameters.    public A(String p1, 
String p2, String p3) {        //...just do something.

    }    public B getInstanceOfB() {        b = 
BeanProvider.getContextualReference(B.class, false);        return b;

    }

}

//--Class Caller--@Named

public class Caller {    //...    public void action() {        A a = new 
A("s1", "s2", "s3");        B b = a.getInstanceOfB(); //<-------- I cannot get 
an instance of B.    }    //...

}

The class A is a non-managed bean, and Caller is managed.

Am I do wrong with BeanProvider? What should I do to get the instance of B?Ps. 
I cannot make the class A managed, it may cause refactoring of all project. 
(~that's awful~)And according to the error log, it seems that a missing 
InjectionPoint may caused this problem.

Many thanks for your help!
