Migrating JSF 1.2 to 2.x resulted in java.lang.NullPointerException at com.sun.faces.config.InitFacesContext.cleanupInitMaps

Question

I'm in process of migrating a JSF 1.2 application to JSF 2.x. My application is using the following APIs:

maven-jetty-plugin (version 6.1.10)
maven-compiler-plugin (version 2.3.1)
myfaces-api & -impl (version 1.2.7)
jsf-facelets (version 1.1.14)
richfaces (version 3.3.3)
javax servlet jstl (version 1.2)
javax servlet-api (version 2.5)
and some other plugins as well.

I updated the versions in faces-config.xml file and removed Facelets 1.1.14 libs and replaced MyFaces 1.2 by JSF 2.x libs, however the application didn't work. It threw the following exception:

    Could not instantiate listener org.apache.myfaces.webapp.StartupServletContextListener
java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener

skuntsel-- Sir, I've tried that configurations but it didn't work. I think, after adding JSF 2.x libs, some other plugins should be updated as well. Simply, I don't know which ones. — nudastack, Jun 28 '13 at 14:24
Just ask a more specific question about the specific problem you're currently facing. Do you get an exception? Ask a question about exactly that exception. You will get an answer how to solve exactly that exception. Then you can advance to the next step. If it also causes an exception, then ask another new question about exactly that exception. Etcetera. You just can't put this all overgeneralized in a single question. This is not going to work in Stack Overflow, which is a Question & Answer site. — BalusC, Jun 29 '13 at 20:01
I have edited my question and shared the exception that I got. What steps should I follow now? — nudastack, Jul 01 '13 at 08:57
The community has voted 5 times to reopen the question. Your question is now reopened. As to the exception, this may happen if you're mixing multiple JSF impls/versions. As per the stacktrace, Mojarra is currently being used (whereas you previously used MyFaces). Perhaps you've still some MyFaces artifacts roaming around? Mojarra cannot find its own `FacesContext` anywhere, it returned `null` and caused this NPE. Please list the libraries you're currently using in webapp's runtime classpath. Please also list the JSF related configuration entries you currently have in webapp's `web.xml`. — BalusC, Jul 01 '13 at 12:09
The pom.xml and web.xml files that I have shared are the original working files in my app. However, when I replaced the JSF-Facelets 1.1.14 by JSF 2.x libs, the app threw the NPE as I shared before. Here, which libs should I remove and by which libs should I replace? — nudastack, Jul 01 '13 at 14:17
You should remove Facelets 1.x and replace JSF (MyFaces) 1.2 by JSF 2.0. Your pom.xml still shows the old config. — BalusC, Jul 01 '13 at 14:46
I did the same as you told but there are lots of exception. I updated the pom.xml and exceptions in the question above. What could be the cause of that many exceptions? — nudastack, Jul 02 '13 at 11:58
One exception at a time, please. As commented before, just investigate and fix the first one occurring. It might as well magically fix all subsequent exceptions because they can be caused by the first exception. If you get a new one afterwards, then just post a new question about exactly that exception. The current one of `java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener` is rather easy. I will post an answer. — BalusC, Jul 02 '13 at 12:01
Please do not change an existing question if you have a new question. It would make all answers completely worthless and confusing for case someone else stumbles upon your question in the future. As said, **ask a new question for every new question**. This is a question & answer site, not a chat box or a legacy discussion forum or so. They only end up in a mess where nobody can find true answers. — BalusC, Jul 02 '13 at 17:03

java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener

As the package name hints, this is a MyFaces-specific class which is obviously not available anymore when you replace MyFaces 1.2 by Mojarra 2.0 instead of MyFaces 2.0.

This class is usually been referenced as <listener> entry in webapp's web.xml. If you remove the whole <listener> entry from web.xml, then this exception should disappear. You usually don't need to explicitly declare one yourself as this is already registered in the TLD file. However, Jetty has some bugs with that and you'd need to explicitly register it yourself. For Mojarra, that would be:

<listener>
   <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>

An alternative is to upgrade to MyFaces 2.0 instead of Mojarra 2.0. The same listener class is present over there.

Migrating JSF 1.2 to 2.x resulted in java.lang.NullPointerException at com.sun.faces.config.InitFacesContext.cleanupInitMaps
