In that tutorial, they chose "liferay MVC" as the portlet framework. In my case i chose JSF2.0. But what can be the root cause of this exception. What is it looking for i couldn't see.

This part of the stacktrace indicates that you are using PortletFaces Bridge:

Caused by: java.lang.NullPointerException
at org.portletfaces.bridge.GenericFacesPortlet.init(GenericFacesPortlet.java:126)

When you get a chance, please upgrade to Liferay Faces Bridge and let us know if you still see the problem.

Hi Neil,

I don't have the same exceptionbuti have this now

Caused by: java.lang.NullPointerException
at javax.portlet.faces.GenericFacesPortlet.init(GenericFacesPortlet.java:92)
at com.liferay.portlet.InvokerPortletImpl.init(InvokerPortletImpl.java:272)
at com.liferay.portlet.PortletInstanceFactoryImpl.init(PortletInstanceFactoryImpl.java:228)
at com.liferay.portlet.PortletInstanceFactoryImpl.create(PortletInstanceFactoryImpl.java:145)

I remove the portlet faces bridge replace it by the Liferay Faces Bridge. What can be the matter now?

[10年前 に Jean Marie によって更新されました。]

Hi Neil,

I look into the source code of javax.portlet.faces.GenericFacesPortlet and some ideas cme out. The exception occurs on line 92 where you can look at this instuction:
// Initialize the bridge implementation instance.
getBridge().init(portletConfig);

It seems there is no way to find this bridge because, here the code is looking for this class: javax.portlet.faces.BridgeImplClass

I did not see this class somewhere even in the liferay-faces-bridge-api-3.1.3-ga4 library i download. Can you tell me more?

Hello Jean,

You will need to make sure that you are using the Liferay Faces Bridge api jar, as well as the impl jar, and the util jar. Here are links to the latest released versions of those:
https://www.liferay.com/community/liferay-projects/liferay-faces/download

You should probably just replace what you have using all of the jars that are downloadable there
1) api
2) impl
3) util
4) alloy
5) portal

Hope that helps,
Vernon Singleton

Thanks vermon, it's ok now. So as a lesson learned one should take all those jars in the class path.
