Hello!

The short answer to your question is 'No'. The longer answer to your question
is 'sorta'. There's a couple of ways you could go about this. Depending
upon why you want to do this, the answer could be as simple as connection
pooling. You could take advantage of a JDBC driver that implements connection
pooling, or even roll your own connection pooling mechanism. You could write
your own Connection Manager that only created a single connection and farmed
out a reference to that connection whenever a JavaBean requested one.

The second solution would be to use a servlet that implements the SingleThreadedModel
interface and have it maintain a reference to the Connection object. Then
you could simply have your JSP grab the reference and pass it to the JavaBean.

With a little more information as to what you are trying to do, I could give
you more specific directions.

I hope this is helpful. Happy Coding!

Cordially,
