This is a question that i just did from the www.je22certificate.com exam
Questions like this really annoy me, i dont understand it
Question:
Which of the following statements correctly declares an element that allows the output result of a specified resource to be inserted in a JSP page? [Check all correct answers]
One of the correct answers:
The jsp:forward action also includes the output generated from the resource specified by the page attribute into the including JSP. However, jsp:forward terminates the execution of the current page whereas the jsp:include action resumes processing in the calling JSP page, once the inclusion is completed.
Now im always so careful about everything in the answer, how can a forward be considered to "include" the output generated into the the JSP page

i don't think so because it clearly says output of the resource is included in jsp . this stands true only if we use include not forward because output of forward is not included in parent jsp.

hi,
To my sense, explanations supplied by j2eecertificate.com are right.
We may say that forward action has for effect to include the output of the target file to the output of forwarding resource: if not, how would be this process transparent for the client? You always see the same URL in the browser, right? So, the output still belongs behind the scene to the including file.
So, what differs from include action?
- First, uncommitted output in the response buffer is automatically cleared before the forward
- Second, the target resource terminates the execution.
HTH,
Regards,
Cyril.
