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.

• Constants.BINARY_BUFFER_SIZE_SERVLET_CONTEXT_INIT_PARAM
• Constants.TEXT_BUFFER_SIZE_SERVLET_CONTEXT_INIT_PARAM

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

upgradeHttpToWebSocket

public void upgradeHttpToWebSocket(Object httpServletRequest,
 Object httpServletResponse,
 ServerEndpointConfig sec,
 Map<String,String> pathParameters)
                            throws IOException,
DeploymentException

Description copied from interface: jakarta.websocket.server.ServerContainer

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.

Specified by:

upgradeHttpToWebSocket in interface ServerContainer

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:

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
