Tomcat 5.5.23 Will Not Unpackage Application

[neilac333]

I am attempting to deploy a proof-of-concept JSF application to Tomcat 5.5.23. I am using Ant to generate my WAR file, whose format is as follows:

META-INF/
META-INF/MANIFEST.MF
index.html
index.xhtml
result.xhtml
WEB-INF/
WEB-INF/classes/
WEB-INF/classes/test/
WEB-INF/classes/test/PersonBean.class
WEB-INF/faces-config.xml
WEB-INF/web.xml
WEB-INF/lib/
WEB-INF/lib/jsf-facelets.jar
WEB-INF/lib/myfaces-api-1.1.5.jar
WEB-INF/lib/myfaces-impl-1.1.5.jar
WEB-INF/lib/tomahawk-1.1.3.jar
WEB-INF/lib/commons-beanutils-1.7.0.jar
WEB-INF/lib/commons-codec-1.3.jar
WEB-INF/lib/commons-collections-3.1.jar
WEB-INF/lib/commons-digester-1.6.jar (KEEP THIS ONE IN MIND!!)
WEB-INF/lib/commons-el-1.0.jar
WEB-INF/lib/commons-lang-2.1.jar
WEB-INF/lib/commons-logging-1.0.4.jar

--------------------------

However, Tomcat does not deploy the application and reports the following:

---------------------------------

I have no idea why Digester isn't found by the class loader since, as you saw, it is included in the WAR file. Any insight into the nature of this problem is very much appreciated.

Thanks very much.
