Subject RE: NullPointerException, pizza, searching
Date Thu, 25 Jul 2002 22:10:37 GMT
I removed the pizza jar (and removed its entry in
jars.xml, rebuilt and I still can't access the Search
the Docs section in the samples. It seems that all XSP
pages do not work. Is pizza required for this? It
seems like it is required for anything XSP.


The error I am getting now is:
org.apache.cocoon.ProcessingException: Lookup of
generator for role 'serverpages' failed.:
org.apache.avalon.framework.component.ComponentException:
UnnamedSelector: ComponentSelector could not find the
component for hint: serverpages

Is there another 2.1 branch I can use? I was using
2.0.3 but was getting errors when trying to index some
xml docs using the indexer you can run from the
"Search the Docs" section.
