MyFaces
MyFaces is used as the JSF implementation in this application. The following details should be added in web.xml

PrimeFaces Theme
As said before, PrimeFaces library is used to enhance the UI. There is nearly no configuration required for this library. PrimeFaces provides many pre-designed theme for your web application. In our case, we use “blue-sky” theme. We just add the following setting in web.xml
<context-param>
  <param-name>primefaces.THEME</param-name><param-value>glass-x</param-value></context-param>

JSF and Spring Integration:
To integrate JSF with Spring, you have to specify the SpringBeanFacesELResolver in Faces-config.xml
Faces-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"

  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
   <application>
     <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
   </application>
   <factory>
 <partial-view-context-factory>org.primefaces.context.PrimePartialViewContextFactory</partial-view-context-factory>
   </factory> 
</faces-config>

MongoDB connection Details
In to order connect to MongoDB, you have to register a MongoDbFactory instance in XML. The connection details is specified in spring-application-context.xml

spring-application-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

hi . i have read your tutorial on integration of myfaces and primefaces.

I have write a small webapp with myfaces+ primefaces and i use the component.
I have deployed on tomee server that came with myfaces implemntation of jsf2.
But i get the error that the app not can start.
I have put int oweb-inf/lib also the common-io.jar and fileuplod.jar fro mapache for upload.
but from the log i get :
