Question

I have an existing JSF 2.0 project working on a Tomcat 7.0.4 server. I am trying to add Icefaces 2.0.0 Beta2 to this project. I downloaded the file ICEfaces-2.0.0-Beta2-bin.zip from Icefaces official homepage and followed the instructions described here.

I copied the 4 files icefaces.jar, icepush.jar, icefaces-ace.jar and icefaces-compat.jar from the ICEfaces-2.0.0-Beta2-bin/icefaces/lib directory to the WEB-INF/lib directory (the one that I included all my jars). The jsf-api.jar and jsf-impl.jar was already included in my project so these was not copied.

When I deployed the webapp to the Tomcat 7 server, following error occured:

/home/user > ant deploy reload

Buildfile: build.xml

build:

deploy:

reload:
   [reload] FAIL - Encountered exception java.lang.IllegalStateException: Container org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/wtree-www] has not been started

BUILD FAILED
FAIL - Encountered exception java.lang.IllegalStateException: Container org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/wtree-www] has not been started

Total time: 0 seconds

This is from the catalina.log, I think this might be intresting:

I don’t understand how copying the 4 files can generate this error. I haven’t done anything else Can you please help me?

Answer 1

As usual, the caused by part of the exception stacktrace tells about the root cause of the problem. In your case it’s the following:

Caused by: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

This is pretty self-explaining. The mentioned class is missing in the runtime classpath. Add commons-logging.jar to /WEB-INF/lib and this particular problem should go. If you don’t already have it somewhere else (in IceFaces download maybe?) then you can just get it at http://commons.apache.org/logging.
