What can it be, init() did not called?

Hi, everybody,

I wrote a servlet, there are standard Methods like init() (without parameters), doPost(), doAll(), doGet(). But i found that init() is not called at all. There is no log file to be written.
So anyone has idea, what can it be?

Thanks!!

Probably an error in configuration.

Exactly what happens if you try to open the URL in a browser?

(If you are using MSIE make sure that "friendly" error messages are turned off.)

Has the servlet been requested? The container can choose to delay calling init() until it actually has to.

Make sure you put @Override annotations on all methods that are intended to override some other method. (For example, "doAll" is not a standard servlet method.)

Why dont you post your code? Your servlet is extended from which class?

actualy I wrote many servlets, all extends from the class HttpServlet. The problem is, all other servlets work fine, only one of them is "empty", just no any reaction, all of them seems like very closely in the code-structur, why just only one?

Sindy , the information you have posted is not enough .......
If I ask you a question like "I have 100 cows , why one of them is white in colour?"...what would be your answer?

So post the problem creating code here , provide us details of your servlet configuration/mapping (if possible web.xml itself) , your server ..etc.

lol dude

@Sindy:
Please post the code for just the servlet that's been bothering you. And other supporting code too.
Maybe someone else will find what you've been missing all this time.
