Thanks Mathias,
I solved my problem the way you suggested.
I have a managed bean allContacts with a managed property dabataseConnection that is set during session start and takes the connection from the sessionScope.
This databaseConnection property is used to initialise the (static) connection property of each Contact bean in the contactList of the allContacts bean. This is done in the getContactList method of the allContacts bean.
Thanks for the help Jan

Hi Jan,
Remember: You should not do bussiness logik in the presentation layer. ThatÂs why it is and will be not possible that way.
Try to use a managed bean which initializes and holds your contact list. Provide a getContacts() method in that bean which returns the initialized contact beans. While initializing the contacts you take the connection and call the setConnection method for each contact.
Example:
<h:datatable value="#{data.contacts}" var="contact"> <h:column> ... <h:outputText value="#{contract.name}" /> </h:column> ... </h:datatable
Ps: do you load every contact through a separate database query? If so try loading the contacts in a single database call. It will increase performance a lot.

That's not what I meant. I want to set the database connection property of each Contact bean to a Connection object that is stored in sessionScope. The Contact beans are stored in an ArrayList called contactList of the allContacts bean. By using the <h:dataTable> I get a reference to each contact bean stored in the contactList of my managed bean allContacts. So I have a reference to each contact bean and now I want to set the database connection property of each contact bean to the Connection object stored in sessionScope.
First I though of specifying this in <faces-config> in the web.xml file but I can't because the number of Contact beans stored in the contactList of the allContacts managed bean aren't known in advance. This means I can't make each Contact bean of the contactList a managed bean.
Greetings Jan
