  `void`
  `upgradeHttpToWebSocket(Object httpServletRequest, Object httpServletResponse, ServerEndpointConfig sec, Map<String,String> pathParameters)`
  Upgrade the HTTP connection represented by the `HttpServletRequest` and `HttpServletResponse` to the WebSocket protocol and establish a WebSocket connection as per the provided `ServerEndpointConfig`.

  - ### addEndpoint

    void addEndpoint(Class<?> clazz) throws DeploymentException
    Throws:
      `DeploymentException`

  - ### addEndpoint

    void addEndpoint(ServerEndpointConfig sec) throws DeploymentException
    Throws:
      `DeploymentException`

  - ### upgradeHttpToWebSocket

    void upgradeHttpToWebSocket(Object httpServletRequest, Object httpServletResponse, ServerEndpointConfig sec, Map<String,String> pathParameters) throws IOException, DeploymentException
    Upgrade the HTTP connection represented by the `HttpServletRequest` and `HttpServletResponse` to the WebSocket protocol and establish a WebSocket connection as per the provided `ServerEndpointConfig`.

    This method is primarily intended to be used by frameworks that implement the front-controller pattern. It does not deploy the provided endpoint.

    If the WebSocket implementation is not deployed as part of a Jakarta Servlet container, this method will throw an `UnsupportedOperationException`.

    Parameters:
      `httpServletRequest` - The `HttpServletRequest` to be processed as a WebSocket handshake as per section 4.0 of RFC 6455.
      `httpServletResponse` - The `HttpServletResponse` to be used when processing the `httpServletRequest` as a WebSocket handshake as per section 4.0 of RFC 6455.
      `sec` - The server endpoint configuration to use to configure the WebSocket endpoint
      `pathParameters` - Provides a mapping of path parameter names and values, if any, to be used for the WebSocket connection established by the call to this method. If no such mapping is defined, an empty Map must be passed.
    Throws:
      `IllegalStateException` - if the provided request does not meet the requirements of the WebSocket handshake
      `UnsupportedOperationException` - if the WebSocket implementation is not deployed as part of a Jakarta Servlet container
      `IOException` - if an I/O error occurs during the establishment of a WebSocket connection
      `DeploymentException` - if a configuration error prevents the establishment of a WebSocket connection
