Class WsServerContainer

java.lang.Object
org.apache.tomcat.websocket.WsWebSocketContainer
org.apache.tomcat.websocket.server.WsServerContainer
All Implemented Interfaces:
ServerContainer, WebSocketContainer, BackgroundProcess
public class WsServerContainer extends WsWebSocketContainer implements ServerContainer
Provides a per class loader (i.e. per web application) instance of a ServerContainer. Web application wide defaults may be configured by setting the following servlet context initialisation parameters to the desired values.

  • Method Details

    • addEndpoint

      public void addEndpoint(ServerEndpointConfig sec) throws DeploymentException
      Published the provided endpoint implementation at the specified path with the specified configuration. WsServerContainer(ServletContext) must be called before calling this method.
      Specified by:
      addEndpoint in interface ServerContainer
      Parameters:
      sec - The configuration to use when creating endpoint instances
      Throws:
      DeploymentException - if the endpoint cannot be published as requested

    • addEndpoint

      public void addEndpoint(Class<?> pojo) throws DeploymentException
      Provides the equivalent of addEndpoint(ServerEndpointConfig) for publishing plain old java objects (POJOs) that have been annotated as WebSocket endpoints.
      Specified by:
      addEndpoint in interface ServerContainer
      Parameters:
      pojo - The annotated POJO
      Throws:
      DeploymentException

    • doUpgrade

      @Deprecated public void doUpgrade(HttpServletRequest request, HttpServletResponse response, ServerEndpointConfig sec, Map<String,String> pathParams) throws ServletException, IOException
      Deprecated.
      This method will be removed in Apache Tomcat 10.1 onwards. It has been replaced by upgradeHttpToWebSocket(Object, Object, ServerEndpointConfig, Map)
      Until the WebSocket specification provides such a mechanism, this Tomcat proprietary method is provided to enable applications to programmatically determine whether or not to upgrade an individual request to WebSocket.

      Note: This method is not used by Tomcat but is used directly by third-party code and must not be removed.

      Parameters:
      request - The request object to be upgraded
      response - The response object to be populated with the result of the upgrade
      sec - The server endpoint to use to process the upgrade request
      pathParams - The path parameters associated with the upgrade request
      Throws:
      ServletException - If a configuration error prevents the upgrade from taking place
      IOException - If an I/O error occurs during the upgrade process

    • upgradeHttpToWebSocket

      public 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.

      This method will be part of the Jakarta WebSocket API from version 2.1

      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
