Subject RE: Problem starting up new C2 beta

Hi Alexander,
take a look at the following forwarded email response from Berin Loritsch at
Apache.  If you have the same setup as me, this should do the trick:

That was your whole problem!  Cocoon 2 is designed to work like servlets are
supposed to work: plug and play.

COCOON 1 TO COCOON 2 MIGRATION

Cocoon 1 forces you to place all the jars in the Tomcat lib directory, this
was unnavoidable at the time but it was because of XSP compilation.  Cocoon
2
discovered how to be able to compile XSP without moving the jars out of the
servlet context lib directory.

1) Remove all unnecessary/conflicting jars from $TOMCATH_HOME/lib
2) Replace $TOMCAT_HOME/lib/{xerces/parser jar} with the version of
   Xerces that comes with Cocoon 2.
3) LEAVE ALL COCOON 2 JARS IN ${context}/WEB-INF/lib

Subject: Problem starting up new C2 beta


Hello Cocooners!

I am getting back an old problem when starting up the new C2 beta
distribution:
Package Naming problems in Avalon:

In the log I have:

ERROR   1201    [cocoon  ] (Thread-24): Error compiling sitemap
java.lang.NoClassDefFoundError: org/apache/avalon/logger/AbstractLoggable

	at java.lang.Thread.run(Thread.java:484)


I am quite sure that the class name should be
"org/apache/avalon/framework/logger/AbstractLoggable"
Is it sure that the Avalon and Excalibur jars included in the dist work well
together?
