Question

Answer 1

+2 A:

I would expect to see this if you have a reference to org.apache.myfaces.webapp.StartupServletContextListener in your web.xml, like:

<listener>
     <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

Can you verify that there is no such element?

I had it removed, but i'm still getting:log4j:WARN No appenders could be found for logger (org.apache.commons.digester.Digester.sax).log4j:WARN Please initialize the log4j system properly.Aug 17, 2010 12:43:02 PM org.apache.catalina.core.StandardContext startSEVERE: Error listenerStart

Did you add your log4j.properties file back? Do you have the log4j jar WEB-INF/lib?

Brabster 2010-08-17 19:51:24

yes I did add the .properties file back, but I don't have the log4j jar in my app's web-inf because I noticed there's a log4j-1.2.8.jar under TOMCAT_HOME/shared/lib. Do I need to add it to my WEB-INF folder?

Give it a try - I have a faint recollection of having problems with log4j unless the jar was actually in the webapp's WEB-INF/lib folder on Tomcat.

I did, but now i'm getting:Error configuring application listener of class org.apache.myfaces.webapp.StartupServletContextListenerIf I add all the JSF/JSTL jars that MyEclipse referenced on my development machine, I get this exception:Error configuring application listener of class com.sun.faces.config.ConfigureListenerjava.lang.NoClassDefFoundError: javax/el/ExpressionFactoryI just don't get it, why is JSF being used?

If you are using MyEclipse, did you do the 'Add JSF capabilities...' thing described here http://www.myeclipseide.com/documentation/quickstarts/jsf/? Sounds a little like the IDE might doing things behind the scenes

Brabster 2010-08-17 20:12:43

It indeed look much like that you've either accidently or unawarely added JSF (Faces) facets yourself while creating MyEclipse web project. Just don't do that :) Rightclick project, check Project Facets and uncheck the JSF/Faces ones (and if necessary manually remove the autogenerated JSF related entries from `web.xml`).

Answer 2

+1 A:

Sounds like a classloader hierarchy issue. You should enclose log4j in your WAR file, not put it in the shared libraries of Tomcat.

Also, I had some problems with Tomcat 5.5 that was fixed in Tomcat 6.0. You may want to consider upgrading.

It was some kind of class conlfict issue:MyEclipse automatically placed the JSTL and JSF jars in my lib path, in addition I noticed that there's a class "Logger" in JSTL (org.apache.taglibs.standard.lang.jstl.Logger), once I declared my logger classes using the full apache log4j package name (org.apache.log4j.Logger) it worked!!
