Table A–21
class-loader Attributes

Attribute

Default

Description
|
|
extra-class-path
|
null
|
(optional) Specifies a colon or semicolon separated list of additional
classpaths for this web module. Paths can be absolute or relative to the web module's root,
for example:
extra-class-path="WEB-INF/lib/extra/extra.jar"
|
|
delegate
|
true
|
(optional) If true, the web module follows the standard class loader delegation model
and delegates to its parent class loader first before looking in the local
class loader. You must set this to true for a web application
that accesses EJB components or that acts as a web service client or endpoint.
If false, the web module follows the delegation model
specified in the Servlet specification and looks in its class loader before
looking in the parent class loader. It’s safe to set this to false only for a web module that does not interact with any other modules.
|
|
dynamic-reload-interval
|
|
(optional) Not implemented. Included for backward compatibility with
previous Sun Java System Web Server versions.
|
Note – If the delegate element is set to false,
the class loader delegation behavior complies with the Servlet 2.4 specification,
section 9.7.2. If set to its default value of true, classes
and resources residing in container-wide library JAR files are loaded in preference
to classes and resources packaged within the WAR file.
Portable
programs that use this element should not be packaged with any classes or
interfaces that are a part of the Java EE specification. The behavior of a
program that includes such classes or interfaces in its WAR file is undefined.
