Hi,
I have tried to enable the JSF based integration tests with the tomcat web
container. These tests fail becasue the war-jsf war does not start.
The first issue I see is that the expression factory cannot be found.
javax.el.ELException: Unable to find ExpressionFactory of type:
org.apache.el.ExpressionFactoryImpl
at
javax.el.ExpressionFactory.newInstance(ExpressionFactory.java:165)[104:org.ops4j.pax.tipi.tomcat-embed-core:8.0.14.1]
at
javax.el.ExpressionFactory.newInstance(ExpressionFactory.java:104)[104:org.ops4j.pax.tipi.tomcat-embed-core:8.0.14.1]
I have looked into the jetty code and they replace the classloader for the
context (which is a ResouceDelegatingBundleClassloader for the war) with a
newly instantiated ResourceDelegatingBundleClassloader, which uses the
pax-web-jetty-bundle classloader as a parent classloader. If I do the same
in pax-web-tomcat (with pax-web-tomcat-bundle as a parent classloader) el
works, but now I get another error:
org.ops4j.pax.web.pax-web-runtime[org.ops4j.pax.web.service.internal.HttpServiceStarted]

Caused by: java.lang.IllegalStateException: No Factories configured for
this Application. This happens if the faces-initialization does not work at
all - make sure that you properly include all configuration settings
necessary for a basic faces application and that all the necessary libs are
included. Also check the logging output of your web application and your
container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that
you use some special web-containers which do not support registering
context-listeners via TLD files and a context listener is not setup in your
web.xml.
A typical config looks like this;
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

Do you have any idea, what is wrong now?
