public class ParanoidCocoonServlet

extends CocoonServlet

This is the entry point for Cocoon execution as an HTTP Servlet. It also creates a buffer by loading the whole servlet inside a ClassLoader. It has been changed to extend CocoonServlet so that it is easier to add and change functionality between the two servlets. The only real differences are the ClassLoader and instantiating Cocoon inside of it.

Method Detail

getClassPath

protected java.lang.String getClassPath()
                                 throws javax.servlet.ServletException

This builds the important ClassPath used by this Servlet. It does so in a Servlet Engine neutral way. It uses the ServletContext's getRealPath method to get the Servlet 2.2 identified classes and lib directories. It iterates through every file in the lib directory and adds it to the classpath. Also, we add the files to the ClassLoader for the Cocoon system. In order to protect ourselves from skitzofrantic classloaders, we need to work with a known one.

Overrides:

getClassPath in class CocoonServlet

Parameters:

context - The ServletContext to perform the lookup.

Throws:

javax.servlet.ServletException -

addClassLoaderURL

protected void addClassLoaderURL(java.net.URL url)

Adds an URL to the classloader.

Overrides:

addClassLoaderURL in class CocoonServlet

addClassLoaderDirectory

protected void addClassLoaderDirectory(java.lang.String dir)

Adds a directory to the classloader.

Overrides:

addClassLoaderDirectory in class CocoonServlet
