NPE, Facelets, JBoss 5.1.0.GA, JDK 1.6.0-13

[julesl]

hi all...

    I have an application that is running fine in JBoss 4.2.3.GA, JDK 1.6.0-13.   Now, I'm trying to migrate to JBoss 5.1.0.GA.  I have a clean deployment, but JBoss hurls when trying to access a page (welcome page) with the following error:

I removed my el-api and el-ri jars due to another error.  But, I'm a little lost on the cause of this error.  If anyone has some idea, I would appreciate it.

thx

I'm able to get past the error, but running into this stack now:

Try putting this in your web.xml:

<context-param>
   <param-name>com.sun.faces.expressionFactory</param-name>
     <param-value>org.apache.el.ExpressionFactoryImpl</param-value>
 </context-param>

I'm not sure if that will fix it.  Please let me know.

At least in my case this does not help. I have the getting started sample up and running in the browser on glassfish 2.1, now I try to make it possible with maven. Part of the problem here is certainly to get the jetty classpath right :-(

I tried to add el-impl-1.0.jar as a compile dependency, which apparently solves the above problem, but then I get to the next problem, a message about a missing ProjectStage enum (java.lang.NoClassDefFoundError). But that is a different story. I am not sure if it is related with el-impl.
