To activate symbolic links in your web application, specify this property in your web application's sun-web.xml:
<sun-web-app>
<property name="allowLinking" value="true"/>
</sun-web-app>
The default value of this property is false.<virtual-server> level in domain.xml, in which case it will apply to all web applications deployed on the virtual server, unless overridden by a web application's sun-web.xml.
