This is based on a past exam question.

The question is asking to describe the four types of message available using JMS.

Am I missing something or is the question just wrong?

Thanks.

EDIT: There are 5 types

Sun’s JMS Spec 1.1 in Section 3.1.1 lists the same five message types. The question appears to be wrong.
