First, I apologise if this is duplicated - I originally sent this from
the wrong mail account.
More importantly though, I am looking for pointers on tracking down the
following problem:
On trying to access any URL after cocoon/ (whether it be cocoon/blah or
a legitimate, sitemap matched URL), I'm getting the ubiquitous
"org.apache.cocoon.ProcessingException: The sitemap handler's sitemap is
not available." with the exception java.lang.NoClassDefFoundError:
org/apache/cocoon/generation/Generator showing up in cocoon's log.
I'm a little confused here, as that interface is both available on the
classpath and is being reported as having been successfully loaded by
the (or I should say, a) class loader.
I am using Cocoon 2.0 under the integrated JBoss + Tomcat (2.4.3/3.2.3)
Full (partially mail-mangled) stack trace follows:
ERROR (2001-12-05) 16:35.57:530 [cocoon ]
