Thank you.
I my class A, it has a reference to B.
When A is emitted to next bolt, I found that when I access B, it's null.
So I think it's neccesory to implement serializable for B.

I believe you need to implement Serializable for both classes. For example, I
use:
public class A implements Serializable {
public static class B implements Serializable {
public B() {/*default constructor required*/}
@Override
public String toString() { /*stuff*/}
@Override
public boolean equals(Object obj) {/*stuff*/}
@Override
public int hashCode() {/*stuff*/}
}
}
Hope this helps, -Dan

My guess is only if Class A holds a reference to an object of Class B,
otherwise its fine.

my question is if B should implements Serializable to be transfer to another
component ?
