public class BootstrapServlet

extends javax.servlet.http.HttpServlet

A bootstrap servlet to allow Cocoon to run in servlet engines that aren't fully compliant with the servlet 2.2 spec.

This servlet adds a mandatory "context-dir" parameter to those accepted by CocoonServlet, which should point to Cocoon's context directory (e.g. "/path-to-webapp/cocoon"). This directory is used to :

• build a classloader with the correct class path with the contents of WEB-INF/classes and WEB-INF/lib (see ParanoidClassLoader),
• resolve paths for context resources.
