Hello everybody!
I'm writing my first Tomcat web application and I'm establishing a connection to the database and putting it in the controller servlet's context.
Next, I'll have some JavaBeans that want to access the database thru the default connection.
Is it possible for a Javabean to access the connection object stored in the controller servlet's context?
Thanx in advance!

The servlet context is available from the servlet or JSP page that is currently executing. In order to have it available within a JavaBean, you'll have to pass the reference to the servlet context to the bean.
hth,

Oh, I see... You know, that's what I was trying to avoid, passing the connection as a parameter to the bean. Guess I'll have to rethink this all up!
Thank you for your help!

There are some other ways - for example, putting
the ServletContext in the Application Context
or ( less desirably ), the session.
The bean could then lookup the Servlet context
in the Application ( or session ) context.
Another way is passing in the ServletContext
in the Bean Constructor ( a parameter, but done
only once ).
Food for thought,
