anwer for this A and B in mock exam
explanation is "hm is not an attribute "
According to first answer it should be A,B,C,D

For the first question answers are corect(D&E)..and for the second question also answers are correct because hashMap hm is created but it is not bound to the request scope..so answers A & B are correct..

i think you should not mention urgent when you make posts according to Javaranch policy..

Thanks & Regards,

For the first question, 'request' does NOT exist in the EL space. Therefore, ruling those out.

For the second question, 'hw' is a hashmap variable declared in a scriptlet. EL does NOT see those at all. Therefore, ruling those out.

Hope that helps.

This means that "requestScope" is default implicit object in EL ?

[Garlapati Ravi]

there is nothing called default implicit object in EL
