        Description copied from interface: jakarta.servlet.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
        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.

      • getResourcePaths

        public java.util.Set<java.lang.String> getResourcePaths​(java.lang.String path)
        Description copied from interface: jakarta.servlet.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
        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.

      • getResource

        public java.net.URL getResource​(java.lang.String path)
                         throws java.net.MalformedURLException
        Description copied from interface: jakarta.servlet.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
        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:
        java.net.MalformedURLException - if the pathname is not given in the correct form

      • getResourceAsStream

        public java.io.InputStream getResourceAsStream​(java.lang.String path)
        Description copied from interface: jakarta.servlet.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
        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

      • getRequestDispatcher

        public RequestDispatcher getRequestDispatcher​(java.lang.String path)
        Description copied from interface: jakarta.servlet.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
        Parameters:
        path - 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:
        RequestDispatcher, ServletContext.getContext(java.lang.String)

      • getAttribute

        public java.lang.Object getAttribute​(java.lang.String name)
        Description copied from interface: jakarta.servlet.ServletContext
        Returns the servlet container attribute with the given name, or null if there is no attribute by that name. An attribute allows a servlet container to give the servlet additional information not already provided by this interface. See your server documentation for information about its attributes. A list of supported attributes can be retrieved using getAttributeNames.

        The attribute is returned as a java.lang.Object or some subclass. Attribute names should follow the same convention as package names. The Java Servlet API specification reserves names matching java.*, javax.*, and sun.*.

        Specified by:
        getAttribute in interface ServletContext
        Parameters:
        name - a String specifying the name of the attribute
        Returns:
        an Object containing the value of the attribute, or null if no attribute exists matching the given name

        Binds an object to a given attribute name in this servlet context. If the name specified is already used for an attribute, this method will replace the attribute with the new to the new attribute.

        If listeners are configured on the ServletContext the container notifies them accordingly.

        If a null value is passed, the effect is the same as calling removeAttribute().

        Attribute names should follow the same convention as package names. The Java Servlet API specification reserves names matching java.*, javax.*, and sun.*.

        Specified by:
        setAttribute in interface ServletContext
        Parameters:
        name - a String specifying the name of the attribute
        object - an Object representing the attribute to be bound
