public class Default

extends javax.servlet.http.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

Method Detail

init

public void init()
          throws javax.servlet.UnavailableException

Description copied from class: javax.servlet.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)>GenericServlet.init(ServletConfig) 55 , simply override this method and it will be called by GenericServlet.init(ServletConfig config). The ServletConfig object can still be retrieved via GenericServlet.getServletConfig()>GenericServlet.getServletConfig() 55 .

getInitBoolean

private boolean getInitBoolean(java.lang.String name)

---

getInitInt

private int getInitInt(java.lang.String name)

---

getResource

protected org.mortbay.util.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.

---

service

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

Description copied from class: javax.servlet.http.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)>Servlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) 55 method. There's no need to override this method.
