Two J2EE technologies are becoming dominant in the Java environment: Spring and Java ServerFaces.
Spring beans could be easily integrated in a JSF project. Spring Beans can coexists with JSF managed beans or interact directly with the view.
The steps necessary to use Spring in a JSF projects are the following:
Libraries
Spring libraries must be accessible 
web.xml
In web.xml you have to declare your spring listener:
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
To use the request values between the view (jsp/jsf) ad the bean you have to add a second listener:
<listener> <listener-class> org.springframework.web.context.request.RequestContextListener </listener-class> </listener>
faces-config.xml
In faces-config.xml usually you define the managed beans. To use spring beans you have to add the following lines:
<application> <variable-resolver> org.springframework.web.jsf.DelegatingVariableResolver </variable-resolver><code> </application>
applicationContext.xml
In the applicationContext.xml you have to declare your beans like a standard Spring application, the only difference is the property scope:
<bean name ="personMB" class="ch.genidea.ofac.web.jsf.Person" <strong>scope="request"</strong>> <property name= ... /> </bean>
Usually the scope property is set as singleton (default). For the web application you have 3 possibilities:
- request: Scopes a single bean definition to the lifecycle of a single HTTP request; that is each and every HTTP request will have its own instance of a bean created off the back of a single bean definition.
- session: Scopes a single bean definition to the lifecycle of a HTTP Session.
- global session: Scopes a single bean definition to the lifecycle of a global HTTP Session. Typically only valid when used in a portlet context.
page.jsp
In your page you can call the bean directly :
<h:outputText value="First name"/> <h:inputText value="#{personMB.firstName}" id="personName"/>
<h:outputText value="Family name"/> <h:inputText value="#{personMB.lastName}" id="personFamilyName"/>
