        Returns the value of the named attribute as an Object, or null if no attribute of the given name exists.

Attributes can also be set programmatically using ServletRequest.setAttribute(java.lang.String, java.lang.Object). This allows information to be embedded into a request before a RequestDispatcher call.

        Attribute names should follow the same conventions as package names. Names beginning with java.* and javax.* are reserved for use by the Servlet specification. Names beginning with sun.*, com.sun.*, oracle.* and com.oracle.*) are reserved for use by Oracle Corporation.

        You should only use this method when you are sure the parameter has only one value. If the parameter might have more than one value, use ServletRequest.getParameterValues(java.lang.String).

        If you use this method with a multivalued parameter, the value returned is equal to the first value in the array returned by getParameterValues.

        If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via ServletRequest.getInputStream() or ServletRequest.getReader() can interfere with the execution of this method.

        public RequestDispatcher getRequestDispatcher​(String path)
        Description copied from interface: javax.servlet.ServletRequest
        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 specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root. This method returns null if the servlet container cannot return a RequestDispatcher.

        The difference between this method and ServletContext.getRequestDispatcher(java.lang.String) is that this method can take a relative path.

        Specified by:
        getRequestDispatcher in interface ServletRequest
        Parameters:
        path - Path of the resource to be wrapped
        Returns:

        If create is false and the request has no valid HttpSession, this method returns null.

        To make sure the session is properly maintained, you must call this method before the response is committed. If the container is using cookies to maintain session integrity and is asked to create a new session when the response is committed, an IllegalStateException is thrown.

        Specified by:
        getSession in interface HttpServletRequest
        Parameters:
        create - Create a new session if one does not exist
