class-loader

The class loader for the virtual server or the web application. There is a default

class loader for the virtual server if you don’t specify one. Classes loaded by the

virtual-server-level class loader are not dynamically reloaded.

You can use the

ServletContext.getAttribute method to retrieve the class

loader and the class loader’s classpath or reload interval for a context. For more

information, see Chapter 7, “API Clarifications.”

Subelements: none

Attributes: none

filter, filter-mapping

These elements implement the Filter API from the Servlet 2.3 specification. Used

within a

web-app element.

Although iPlanet Web Server 6.0 supports only the Servlet 2.2 API in the

web.xml

file, the Filter API from the Servlet 2.3 specification is available in the

web-apps.xml file.

The

filter and filter-mapping elements implement the Filter API. They are

both subelements of a

web-app element in the web-apps.xml file. Except for their

file location,

filter and filter-mapping are as described in the Servlet 2.3

specification. For more information, see:

http://java.sun.com/products/servlet/index.html

classpath The classpath used by the class loader.

delegate Specifies that the class loader for the virtual server or system

is called first to load a class. Allowed values are true and

false. The default is false.

reload-interval The time interval in seconds within which the server checks

for web applications being modified. The default is 30.
