The presentation tier integration actually involves the following steps:
Creating JSP pages<navigation-rule> <from-view-id>/pages/login.jsp</from-view-id> <navigation-case> <from-outcome>reg</from-outcome> <to-view-id>/pages/registration.jsp</to-view-id> </navigation-case> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/pages/successLogin.jsp</to-view-id> </navigation-case> <navigation-case> <from-outcome>failure</from-outcome> <to-view-id>/pages/login.jsp</to-view-id> </navigation-case> </navigation-rule> <navigation-rule> |
Developing and configuring backing beans
In our application there are two backing beans Bean and CheckValidUser.
Following code in the faces-config.xml
file declares the backing beans:
<application> <locale-config> <default-locale>en</default-locale> </locale-config> <message-bundle>net.roseindia.web.ui.messages</message-bundle> </application> <managed-bean> <managed-bean-name>Bean</managed-bean-name> <managed-bean-class>net.roseindia.web.ui.Bean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> <managed-bean> <managed-bean-name>CheckValidUser</managed-bean-name> <managed-bean-class>net.roseindia.web.ui.CheckValidUser</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> |
and finally integrating JSF with business logic
tier
We are using ServiceFinder class to get the Spring managed bean.
FacesContext context= FacesContext.getCurrentInstance(); ServletContext servletContext = (ServletContext)context.getExternalContext().getContext(); ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(servletContext); Object o =appContext.getBean(beanName); |
