how to create session


How can I create simple session in java class and assign a value. Remember I'm not using servlet. My Servlet is making call to other class a, and class a is calling class b etc., I like to know how can I set some value in class b based on some condition. So that finaly when it comes to <servlet fwd JSP> based on session value I can display few thing to user.

Who is Participating?
u can apss the session and
if condition is not satisfied u can do

It's not really nice code, but should work.
U can wait for comments of other experts.
Not sure I follow but,
from the servlet, create the sessions and pass the session object to the classes ?

it's not possible in a regular class,
that's why I said to create in servlet and pass to regular classes.

But thing is based on certain condition or so i want to create session value if condition is not satisfied then i dont want to create session.
matthew016's statement is valid and correct. You can't create session from *normal* Java class.

What you can do is to pass one flag or variable back to your Servlet from your Java class to indicate whether you need to create session or not.

Hope that helps
or else
you can  pass the session object it self to the method that is being called from your servlet
and set the session value in that method based on some condition.
if you are using any web /app servers, you can store the value in a properties object (java.util.Properties) and read it where ever you want.

You will have one instance of the Properties object through out the server. In this case you need not return the values as method return types.

Hope this helps
