Accessing JavaBeans from Servlets

Thread view:

I initialized a JavaBean at the startsite of my web application with
the scope "session" and set the initial values of the properties. All
the following JSP-sites of my application are working very well with
this JavaBean, but I'm using servlets too and need access to the
current values of my JavaBean. If I try to access it with

javabean j = new javabean();

the engine is obviously creating a new instanz with empty (null)
properties. How can I access the JavaBean from my servlets?

Thanx

Matthias

When you create a bean in session scope via a <jsp:useBean> action,
behind the scenes the bean is stored as a session attribute with the
specified name. From a servlet, then, you can obtain the relevant
session object from the request, and extract the bean you want via the
session's getAttribute method.
