问题
I am trying to deploy a web application in WebSphere 8.5. The app has the following characteristics.
- Mojarra 2.1.13
- Primefaces 3.4.2
- spring webflow 2.3.1
- spring 3.1.2
- jdk 1.6
This app works very well into Tomcat 7 but when we try to deploy it into WebSphere we got a NullPointerException with the following stacktrace.

I see that the error is coming from MyFaces2, JSF implementation by default into websphere 8.5, so I tried to implement Mojarra 2.1.13 as a shared lib but it did not work (I followed the steps from IBM docs).
The other odd thing is that the app rendered the main page but when it is rendering suddenly this error shows up.
- Does someone know something about this error?
回答1:
Piero,
To resolve the problem, add or replace the following context parameter in the web.xml file and republish the project.
<context-param>
<param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
<param-value>false</param-value>
</context-param>
That is because you are using a default JSF implementation for WAS (myFaces) and you have developed in mojarra, so you need to set that in order to work with myFaces.
Saludos
回答2:
I have:
- JSF Mojarra 2.1.7
- Primefaces 3.4.2
- Spring framework 4.0.2.RELEASE
- Spring web flow 2.3.3.RELEASE
- Spring security 3.2.0.RELEASE
I resolved in this mode:
Change class loader of the module in PARENT_LAST
ibm documentation (change class loader policy)
Change JSF Provider
ibm documentation (change jsf provider)
Restart Server (Important!)
