Spring JSF Integration

Spring JSF integration can be achieved by following 2 ways
1) JSF Centric
2) Spring Centric
Recommended approach is Spring Centric using Spring Webflow.

Spring Webflow is on top of Spring MVC. Using webflow a complex
flow can be configured using xml mapping.

Steps for integrating Spring-JSF using Spring WebFlow2

1) In web.xml, configure

2) Persistence.xml
