Subject Re: HOw to send form parameters to dao in struts2 with hibernate?
Date Thu, 28 Feb 2008 09:42:31 GMT


How is the service implementation layer being instantiated? 

The best way is to use the Spring plugin as defined at to inject objects
into your actions manage dependancy injection.

For more on interceptors and what they do, see for detail.

Finally, might be worth having a read through the manual at which although
aimed at devs, has a good insight into the framework.
