here 'vec' is the servlet prog name and the class name itself, whose class file is been placed in classes folder inside web-inf dir.

i am new to servlet technology. i have written my first servlet program and placed it in web-inf/classes folder in tomcat. and my html page in root directory. the issue is whether i should configure web.xml file or not?(although i configured it, i got 404 error, saying that the particular servlet file is not found).
i have heard my friend saying that when we place html file in root directory, we do not need to configure xml file. why is that so?? can someone explain please..

hi everybody, i am new to servlets. i have installed j2ee5.0 sdk in my system and tried to compile a helloworld servlet program. i do not know where to save my program in the sdk directory. i have tried it saving in bin directory but my program gave err saying, "javax.servlet package does not exist".
once i get a class file, i know how to deploy my servlet.
please tell me the exact path to save my program so that i could compile it.

hi everybody, i had just completed my scjp1.5 course and about to start with scjd. I did not know anything about scjd, but i am very interested to go ahead and explore it... i have also searched some details from net, but if you people feel some link to be very useful for beginners, then please let me know them...
the toughness level of the questions was equal to the one given in kathy book chapter wise questions.
as i did not prepare generics and threads well, i lost my marks in those topics.
overall, threads was the toughest part in the exam and i was completely exhausted answering them(i got lot of questions from threads), but if you are prepared then it hope it will be bit easier .

PriorityQueue<Integer> p=new PriorityQueue<Integer>(???,pqs);

The above line is taken from a program, where pqs represents the object of a comparator. but i do not know what is the first argument there. actually it is given as
PriorityQueue<Integer> p=new PriorityQueue<Integer>(10,pqs);
please explain..
i have seen programs where
arg1 is used as a key and arg2 as value and, vise-versa. is it possible to use
arg2 as key and arg1 as value??? if so, while we retrieve the value from buckets will not there be any prob???
sorry, i should have told like,
you can instantiate it within the same class(ie. class with constructor marked as private)

you have two cases here.
1)you can instantiate the class with it.
2)but, you either cannot extend the class nor instantiate it outside the class

i think this helps you..??
