Re: jspwiki "You tried to instantiate an abstract class com.ecyrd.jspwiki.PageManager"

Yes...!
You need to delete the log4j.jar and the commons-logging.jar from jspwiki's lib directory, and let it use jboss's own versions of these. (If the latter one isn't found in JBoss lib directory, move it there). 


I haven't investigated why the problem manifests as this type of 
exception, but that was the reason in my case.


By the way, JBoss 4.2.2 actually has Tomcat 6 embedded in it, not 5.5.

Cheers...

Hi,


I'm trying to run JSPWiki on JBoss 4.2.2 with Tomcat 5.5 embedded and 
java 1.6.  Can anyone give me a hint on why I get this error?

Thanks,
