  • Method Details

    • getContextHandler

      public ContextHandler getContextHandler()
      Deprecated.
    • getContext

      public ServletContext getContext(String uripath)
      Deprecated.
      Description copied from interface: ServletContext
      Returns a ServletContext object that corresponds to a specified URL on the server.

      This method allows servlets to gain access to the context for various parts of the server, and as needed obtain RequestDispatcher objects from the context. The given path must be begin with "/", is interpreted relative to the server's document root and is matched against the context roots of other web applications hosted on this container.

      In a security conscious environment, the servlet container may return null for a given URL.

      Specified by:
      getContext in interface ServletContext
      Overrides:
      getContext in class ContextHandler.StaticContext
      Parameters:
      uripath - a String specifying the context path of another web application in the container.
      Returns:
      the ServletContext object that corresponds to the named URL, or null if either none exists or the container wishes to restrict this access.
      See Also:
    • getMimeType

      public String getMimeType(String file)
      Deprecated.
      Description copied from interface: ServletContext
      Returns the MIME type of the specified file, or null if the MIME type is not known. The MIME type is determined by the configuration of the servlet container, and may be specified in a web application deployment descriptor. Common MIME types are "text/html" and "image/gif".
      Specified by:
      getMimeType in interface ServletContext
      Overrides:
      getMimeType in class ContextHandler.StaticContext
      Parameters:
      file - a String specifying the name of a file
      Returns:
      a String specifying the file's MIME type
    • getRequestDispatcher

      public RequestDispatcher getRequestDispatcher(String uriInContext)
      Deprecated.
      Description copied from interface: ServletContext
      Returns a RequestDispatcher object that acts as a wrapper for the resource located at the given path. A RequestDispatcher object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.

      The pathname must begin with a "/" and is interpreted as relative to the current context root. Use getContext to obtain a RequestDispatcher for resources in foreign contexts. This method returns null if the ServletContext cannot return a RequestDispatcher.

      Specified by:
      getRequestDispatcher in interface ServletContext
      Overrides:
      getRequestDispatcher in class ContextHandler.StaticContext
      Parameters:
      uriInContext - a String specifying the pathname to the resource
      Returns:
      a RequestDispatcher object that acts as a wrapper for the resource at the specified path, or null if the ServletContext cannot return a RequestDispatcher
      See Also:
    • getRealPath

      public String getRealPath(String path)
      Deprecated.
      Description copied from interface: ServletContext
      Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext..

      The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive).

      Specified by:
      getRealPath in interface ServletContext
      Overrides:
      getRealPath in class ContextHandler.StaticContext
      Parameters:
      path - a String specifying a virtual path
      Returns:
      a String specifying the real path, or null if the translation cannot be performed
    • getResource

      public URL getResource(String path) throws MalformedURLException
      Deprecated.
      Description copied from interface: ServletContext
      Returns a URL to the resource that is mapped to a specified path. The path must begin with a "/" and is interpreted as relative to the current context root.

      This method allows the servlet container to make a resource available to servlets from any source. Resources can be located on a local or remote file system, in a database, or in a .war file.

      The servlet container must implement the URL handlers and URLConnection objects that are necessary to access the resource.

      This method returns null if no resource is mapped to the pathname.

      Some containers may allow writing to the URL returned by this method using the methods of the URL class.

      The resource content is returned directly, so be aware that requesting a .jsp page returns the JSP source code. Use a RequestDispatcher instead to include results of an execution.

      This method has a different purpose than java.lang.Class.getResource, which looks up resources based on a class loader. This method does not use class loaders.

      Specified by:
      getResource in interface ServletContext
      Overrides:
      getResource in class ContextHandler.StaticContext
      Parameters:
      path - a String specifying the path to the resource
      Returns:
      the resource located at the named path, or null if there is no resource at that path
      Throws:
      MalformedURLException - if the pathname is not given in the correct form
    • getResourceAsStream

      public InputStream getResourceAsStream(String path)
      Deprecated.
      Description copied from interface: ServletContext
      Returns the resource located at the named path as an InputStream object.

      The data in the InputStream can be of any type or length. The path must be specified according to the rules given in getResource. This method returns null if no resource exists at the specified path.

      Meta-information such as content length and content type that is available via getResource method is lost when using this method.

      The servlet container must implement the URL handlers and URLConnection objects necessary to access the resource.

      This method is different from java.lang.Class.getResourceAsStream, which uses a class loader. This method allows servlet containers to make a resource available to a servlet from any location, without using a class loader.

      Specified by:
      getResourceAsStream in interface ServletContext
      Overrides:
      getResourceAsStream in class ContextHandler.StaticContext
      Parameters:
      path - a String specifying the path to the resource
      Returns:
      the InputStream returned to the servlet, or null if no resource exists at the specified path
    • getResourcePaths

      public Set<String> getResourcePaths(String path)
      Deprecated.
      Description copied from interface: ServletContext
      Returns a directory-like listing of all the paths to resources within the web application whose longest sub-path matches the supplied path argument. Paths indicating subdirectory paths end with a '/'. The returned paths are all relative to the root of the web application and have a leading '/'. For example, for a web application containing

      /welcome.html
      /catalog/index.html
      /catalog/products.html
      /catalog/offers/books.html
      /catalog/offers/music.html
      /customer/login.jsp
      /WEB-INF/web.xml
      /WEB-INF/classes/com.acme.OrderServlet.class,

      getResourcePaths("/") returns {"/welcome.html", "/catalog/", "/customer/", "/WEB-INF/"}
      getResourcePaths("/catalog/") returns {"/catalog/index.html", "/catalog/products.html", "/catalog/offers/"}.
      Specified by:
      getResourcePaths in interface ServletContext
      Overrides:
      getResourcePaths in class ContextHandler.StaticContext
      Parameters:
      path - the partial path used to match the resources, which must start with a /
      Returns:
      a Set containing the directory listing, or null if there are no resources in the web application whose path begins with the supplied path.

      Deprecated.
      Description copied from interface: ServletContext
      Returns the servlet container attribute with the given name, or null if there is no attribute by that name.
