OK, here is how i fixed this in my ubuntu 9.04 setup using the normal
tomcatt6 ubuntu package.
I added this permission line to the /etc/tomcat6/policy.d/04webapps.policy
grant {
// Attempt to get Nutch working
permission java.security.AllPermission;
Now I can get the Nutch web app working - but obviously this is
probably not wise for a production public system. In any event this is
now a tomcat and ubuntu problem rather than a Nutch problem.
HOWEVER
Now it doesnt seem to find my previously crawled indexes.... I need to
think some more :-)
