HI Friends, I am going for exam on coming monday, ie. after 3 days. I have following queries. 1> In exam, questions for pattern includes or ask anything in terms of code details or they just mention problem domain or advantage and ask user to select or specify related java pattern? 2> Have anyone encountered question about stateless, connectionless of http or servlet? If yes then please tell me what kind of question it was? 3> In exam, anyone encountered a question related to depricated method or field of standard jsp/servlet classes? 4>web-resource-collection is a set of url-pattern and http-method for authorization. What if a request is matching one of the url-pattern, but request method does not match with one specified in the web-reosurce-collection.? Thanking you all in advance. Regards, Ritesh.
