Integration of Seam Components with JSF

[keithpitty]

Firstly, my apologies if this question is answered elsewhere - I've browsed the Reference Guide and searched the forum without finding the answer yet. I'm relatively new to Seam and am hoping that someone can give me some quick insight.

So, as I understand it, Seam enables EJB 3.0 components to seamlessly integrate with JSF i.e. no need for beans to be configured in JSF via faces-config.xml. In the Ref Guide in section 9.1.1 (Integrating Seam with JSF and your servlet container) I see that org.jboss.seam.servlet.SeamListener is defined as a listener in web.xml and org.jboss.seam.jsf.SeamPhaseListener is defined as a phase listener for the JSF lifecylce in faces-config.xml.

So, my question is: how does Seam achieve the seamless integration? Is it via annotations?

The SeamPhaseListener sets a custom JSF variable resolver.

Thanks Christian.

Actually the VariableResolver is set in a faces-config.xml inside the Seam jar. Strictly we would not even need to specify the Seam PhaseListener in the user's faces-config, but then we would need some other setting to define the Seam TX management (or lack of). So its probably just as easy this way.
