inputFileUpload Problem

[Will Norman]

I am trying to get the inputFileUpload working. 

I get the following error:

java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUpload
        
org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:114)
I am using the JSF RI and Tomahawk 1.1.3

Any help would be greatly appreciated!
