Hello All,

The jsp:useBean action can also optionally accept a beanName attribute which specifies the name of a bean, as expected by the instantiate() method of the java.beans.Beans class. Is this attr. coered in the SCWCD exam?

I have seen it in mock exams.

I couldn't remember whether it was mock test or real test. But what you need to know is Bean name should not appear with the class attribute.

Together beanName and class cannot be used inside jsp:useBean
If you use beanName then type is required.

Adding to your knowledge ...

1. It is more concerned about instantiating a serialized bean.

2. That is why we use 'type' attribute with it, to let the container know, what should the bean be casted to.

3. Also, 'class' is not mentioned because 'class' is more towards creating a new instance when one doesn't exist. But here, we want to bring a serialized bean (existing bean) back into action.

I am sure about '1'. Points '2' and '3' are my extrapolation.
