I deployed a JSF based webapp on the engine at appspot.com. I'm
getting
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at org.apache.myfaces.webapp.filter.ExtensionsFilter.<init>
(ExtensionsFilter.java:144)
I think eclipse uploaded the commons-logging.jar for me (no hassle
while doing the deploy inside eclipse). How can I check that this jar
resides on the appspot.com
I had exactly the same problem with Spring based application -
ClassNotFoundException: org.apache.commons.logging.LogFactory, with
commons-logging-1.1.1.jar in war/WEB-INF/lib directory
The problem is, that App Engine SDK also contains commons-
logging-1.1.1.jar with cripled Commons Logging: the package
org.apache.commons.logging.* is empty and everything is put under
com.google.appengine.repackaged.org.apache.commons.logging.* and
custom jar from WEB-INF/lib got overwritten with the SDK version.
(Leaving the same name I found extremely stupid from Google
developers.)
Solution is simple: put commongs logging into WEB-INF/lib with
different name (commons-logging.jar).
Eclipse plugin creates war which is going to be uploaded to App Engine
in temp directory with name appcfg*.tmp (like C:\Users\martin\AppData
\Local\Temp\appcfg1993864804685917941.tmp).

I am on a mac and renamed the jar, also verified that it was included
in the build being sent to the cloud (on mac /private/tmp/appcfg*) but
still getting the NoClassDefFoundError.
Anybody got this working from a mac?
