From HFSJ Ch. 5 mock exam:

When using a RequestDispatcher, the use of which methods can often lead to an IllegalStateException (Choose all that apply)

a) read
b) flush
c) write
d) getOutputStream
e) getResourceAsStream

Given answer: b
Now, according to the errata, answer c is also one of the correct answers.
My question:
How can the write method, when applied to a RequestDispatcher, result in an IllegalStateException?

Even I am interested in knowing this. I have not checked it in errata, but this is bad news, if there are other errors like this in the book.

Both are OK. If you have a flush and then write the error is done. So b and c.
I agree. Here's the link:
