JavaBean location question

[aostrik]

Hi,

I need to have access to Javabean from *.jsp, servlet and back-end
business classes.
Currently, I create bean instance on web application startup and add it
to web application as the attribute:
getServletContext().setAttribute(bean). Also I store that instance in
the businness class via setter method: myBusinessObject.setBean(bean).

Is it a good technique?
If not what is the common technique for storing this bean?

Thank you.
