Cocoon vs J2ee performance

[Rajeev Singh <rs...@zapapp.com>]

Hi all,
I needed the opinion of the house whether Cocoon is a fit for mission
critical operations where speed is of top priority in comparison with
JSP-Servlet-HTML architecture, using a servlet container only as in
J2ee,(with or without ejb's).

Thx,
Rajeev

You are using old tool with the new libraries.

'Old' here is JDK 1.3.1 or earlier, 'tool' is tools.jar (or javac.jar),
'new libraries' is rt.jar from JDK 1.4.

Correct the error (use either older JDK or newer javac) and try again.

PS javac.jar is located in the cocoon.war/WEB-INF/lib in the webapp, or
in xml-cocoon/lib/ in source distribution.
