The following table describes attributes for the class-loader element.

Table A–21 class-loader Attributes

Attribute  

Default  

Description  

extra-class-path

null 

(optional) Specifies additional classpath settings for this web module. 

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 J2EE specification. The behavior of a program that includes such classes or interfaces in its WAR file is undefined.
