public class WebdavServlet
extends DefaultServlet

Servlet which adds support for WebDAV level 2. All the basic HTTP requests are handled by the DefaultServlet. The WebDAVServlet must not be used as the default servlet (ie mapped to '/') as it will not work in this configuration. To enable WebDAV for a context add the following to web.xml:
<servlet>
<servlet-name>webdav</servlet-name>
<servlet-class>org.apache.catalina.servlets.WebdavServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>webdav</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

This will enable read only access. To enable read-write access add:
<init-param>
<param-name>readonly</param-name>
<param-value>false</param-value>
</init-param>


To make the content editable via a different URL, using the following mapping:
<servlet-mapping>
<servlet-name>webdav</servlet-name>
<url-pattern>/webdavedit/*</url-pattern>
</servlet-mapping>

Don't forget to secure access appropriately to the editing URLs. With this configuration the context will be accessible to normal users as before. Those users with the necessary access will be able to edit content available via http://host:port/context/content using http://host:port/context/webdavedit/content
