Description

under jetty (with jetty-runner) everything is ok.
But I would like to run the application also in tomcat and almost everything works except one thing: Logging component causes NullPointerException. I happens in mcf-authority-service:
2012-08-31 11:06:20 org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [UserACLServlet] in context with path [/mcf-authority-service] threw exception

in mcf-crawler-ui on pages which use Logging:

they all point to lines looking like this:

UserACLServlet.java line 106:
Logging.authorityService.debug("Received request");

or HttpPoster.java line 394:
if (Logging.ingest.isDebugEnabled())

Why is Manfold environment not being initialized? I really need to run it under Tomcat in some cases...
