You copy the codes from the primefaces showcase and added your codes in.
What I see from here is you have added codes in your jsf page which it needs to have app managed bean and customerBean managed bean.

Besides that your PPRBean does not have the annotation for
@ManagedBean (name="listBean")
or have you define your managed bean in the faces-config.xml?

You can have a look in this tutorial for configuring managed bean
http://www.mkyong.com/jsf2/configure-managed-beans-in-jsf-2-0/

and look at this example for using managed bean in jsf
http://www.mkyong.com/jsf2/jsf-2-textbox-example/

Hope this help.

Hi..I was added managed bean entry into faces-config.xml file..

Here is the code

<managed-bean>
<managed-bean-name>listBean</managed-bean-name>
<managed-bean-class>com.mq.updatemanager.web.supportmanager.customermangement.PPRBean </managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>

</managed-bean>


Then also its not working.

You will need to add 2 managed bean class for your following codes, which is App class and CustomerBean class.



For example:



The above is just an example, you will need to complete the others.

Then add these 2 managed bean in your faces-config.xml
