HFSJSP, page 350 says that <jsp:useBean> can also create a bean.

I tried a simple program and I'm seeing below exception:


I further looked into the generated JSP file and it is different from what has been shown in the book:


Can someone please explain why it is not creating a new Person bean and instead throwing an exception?

Thanks!

Is model.Person a concrete class? Does it have a public, no-arguments constructor?

Thanks for your reply!

I read few more pages further and found my mistake:


I didn't specify class.

If you do not specify a class, no bean will be created.
