All Implemented Interfaces:

java.io.Serializable, Servlet, ServletConfig

public class Default
extends HttpServlet

The default servlet. This servlet, normally mapped to /, provides the handling for static content, OPTION and TRACE methods for the context. The following initParameters are supported:

 
 acceptRanges If true, range requests and responses are supported
 
 dirAllowed If true, directory listings are returned if no welcome file is found. Else 403
 Forbidden.
 
 putAllowed If true, the PUT method is allowed
 
 delAllowed If true, the DELETE method is allowed
 
 redirectWelcome If true, welcome files are redirected rather than forwarded to.
 
 minGzipLength If set to a positive integer, then static content larger than this will be served
 as gzip content encoded if a matching resource is found ending with ".gz"
 
 resourceBase Set to replace the context resource base
 
 relativeResourceBase Set with a pathname relative to the base of the servlet context root. Useful
 for only serving static content out of only specific subdirectories.
 
 

The MOVE method is allowed if PUT and DELETE are allowed

init

public void init()
          throws UnavailableException

Description copied from class: GenericServlet

A convenience method which can be overridden so that there's no need to call super.init(config).

Instead of overriding GenericServlet.init(ServletConfig), simply override this method and it will be called by GenericServlet.init(ServletConfig config). The ServletConfig object can still be retrieved via GenericServlet.getServletConfig().

Overrides:

init in class GenericServlet

Throws:

UnavailableException

getResource

protected Resource getResource(java.lang.String pathInContext)
                        throws java.io.IOException

get Resource to serve. Map a path to a resource. The default implementation calls HttpContext.getResource but derived servlets may provide their own mapping.

Parameters:

pathInContext - The path to find a resource for.

Returns:

The resource to serve.

Throws:

java.io.IOException

service

protected void service(HttpServletRequest request,
           HttpServletResponse response)
                throws ServletException,
                       java.io.IOException

Description copied from class: HttpServlet

Receives standard HTTP requests from the public service method and dispatches them to the doXXX methods defined in this class. This method is an HTTP-specific version of the Servlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) method. There's no need to override this method.

Overrides:

service in class HttpServlet

Parameters:

request - the HttpServletRequest object that contains the request the client made of the servlet

response - the HttpServletResponse object that contains the response the servlet returns to the client

Throws:

ServletException - if the HTTP request cannot be handled

java.io.IOException - if an input or output error occurs while the servlet is handling the HTTP request
