Instantiating bean in Servlet

Question

Hi All
I have written a bean that fetches data from another java class. My Servlet instantiates that bean and pass that object reference to another Java class, which is multi-threaded. One thread of that class calls another method of another object using that object reference. so, in that way the object reference of that bean (which is created by the servlet) is passed all over the application and fetches data from there to show in the Servlet.
Now my question is, as Servlet is multithreaded by default, it should create an instance of that bean everytime the servlet is accessed (not by calling from that servlet or any other servlets/JSPs)by different users. And by this way every servlet should have their own bean instances. In my case, when I am running that servlet in my localhost it works fine but at the same time when I try to invoke that servlet again from another browser it passes the bean object reference as null. I dont really understand that. Currently I am creating the bean instance in the class definition. I tried to create the instance in init() method but the problem remains same. If my approach is wrong then where should I create the bean instance.
Thanks in advance.

Thanks very much.
I have no service method. I have doGet() and doPost() method. doGet is called just once to create the login screen in every session. doPost handles the form data and it is called several times.
should I create the bean instance in doGet method then? I have to pass that object reference as an object array in that method parameter. where should I initialize that object array and create the instance of the bean and pass the array to another method. I am passing that object reference to another java class method in doget() method.
Cheers!!
