Hi Satou, This is regarding the This Thread (For Moderators: I was unsure if I posted reply to above mention thread would I get answer therefore I posted it as separate post). The doubt was, the answer given as option E is incorrect as well, because as per JSP2.0 specs, <body-content> is a mandatory subelement of <tag> element, therefore it cannot be missed. So in other words this question has no answer. Another doubt is, normally we define TLD for tag files only when they are package in jar file and the tld should contain <tlib-version> <short-name> and <tagfile> can it also contain <tag> element? Please reply.
