Class DispatcherServlet
java.lang.Object
javax.servlet.GenericServlet
javax.servlet.http.HttpServlet
com.arsdigita.web.BaseServlet
com.arsdigita.web.DispatcherServlet
- All Implemented Interfaces:
- Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
- public class DispatcherServlet
- extends BaseServlet
The CCM main dispatcher. This servlet serves as the main
servlet (mapped to "/someprefix/*") for requests to the CCM
webapp.
Upon finding an application
at the requested URL, this class sets a request
attribute storing the ID of the application and forwards to the
servlet associated with it. If instead no application is found,
the request is forwarded to the fallback servlet, if defined.
This servlet may be deployed using web.xml entries like
these:
<servlet>
<servlet-name>ccm-dispatcher</servlet-name>
<servlet-class>com.arsdigita.web.DispatcherServlet</servlet-class>
<init-param>
<param-name>fallback-servlet</param-name>
<param-value>the-old-site-node-dispatcher</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>ccm-dispatcher</servlet-name>
<url-pattern>/ccm/*</url-pattern>
</servlet-mapping>
It's important to also edit the com.arsdigita.web.Initializer
options to reflect where you've put your dispatcher.
init com.arsdigita.web.Initializer {
...
// This corresponds to a servlet mapping of "/ccm/*" and
// assumes CCM is the default webapp.
dispatcherContextPath = "";
dispatcherServletPath = "/ccm";
...
}
