Question

After extracting TomEE-plus (apache-tomee-1.0.0-plus.zip) and building the jsf example (on examples-4.0.0-src.zip\webapps\jsf), I came across the following error on catalina.*.log with the following message:

SEVERE: An error occured while initializing MyFaces: Class org.apache.openejb.jsf.CustomApplicationFactory is no javax.faces.application.ApplicationFactory

Am I the only one who gets this error? Is there a solution or a workaround?

Answer 1

I posted the same question on TomEE’s forum:
http://openejb.979440.n4.nabble.com/Running-TomEE-plus-jsf-Examples-Fails-td4656561.html and got very nice answers. Here are the steps for running JSF & CDI on TomEE.

1. TomEE used to have a bug on version 1. It is now fixed. That probably caused that error.
2. Overcome this problem by checking out the latest version of TomEE:
   http://openejb.apache.org/builds.html
3. In Order to run a JSF example with cdi on TomEE:
   • Checkout latest example version (SVN checkout from https://svn.apache.org/repos/asf/tomee/tomee/trunk/examples/)
   • Build the project (Maven) on https://svn.apache.org/repos/asf/openejb/trunk/openejb/examples/moviefun/
   • Run moviefun example on the latest TomEE version (navigate to JSF links once it runs).

By the way:
A stable version of TomEE is about to release this September. This would probably cover the problem.
