Subject Re: jspwiki "You tried to instantiate an abstract class com.ecyrd.jspwiki.PageManager"
Date Fri, 04 Apr 2008 18:26:50 GMT
Milton,

When I deleted both of the jar files JSPWiki hung the app server during 
the deploy.  I put log4j back, but not commons-logging.jar, and it worked.

Many thanks for the help!
