Write timeouts The socket timeout facility offered by the JDK applies only to read operations on the socket.

When a client or server is configured, in any of the usual ways, with the parameter org.jboss.remoting.transport.socket.SocketWrapper.WRITE_TIMEOUT (actual value "writeTimeout") set to a positive value (in milliseconds), all write operations will time out if they do not complete within the configured period. When a write operation times out, the socket upon which the write was invoked will be closed, which is likely to result in a java.net.SocketException. Note. A SocketException is considered to be a "retriable" exception, so, if the parameter "numberOfCallRetries" is set to a value greater than 1, an invocation interrupted by a write timeout can be retried.

Since is the first invocation, there will not be and will create a new socket connection and use it for making the invocation. Then when finished making invocation, will return the still active socket connection to the pool. As more client invocations are made, is possible for the number of socket connections to reach the maximum allowed (which is controlled by 'clientMaxPoolSize' property). At this point, when the next client invocation is made, it will wait up to some configured number of milliseconds, at which point it will throw an org.jboss.remoting.CannotConnectException. The number of milliseconds is given by the parameter MicroSocketClientInvoker.CONNECTION_WAIT (actual value "connectionWait"), with a default of 30000 milliseconds. Note that if more than one call retry is configured (see next paragraph), the CannotConnectException will be swallowed. Once the socket client invoker get an available socket connection from the pool, are not out of the woods yet. For example, a network problem could cause a java.net.SocketException. There is also a possibility that the socket connection, while still appearing to be valid, has "gone stale" while sitting in the pool. For example, a ServerThread on the other side of the connection could time out and close its socket. If the attempt to complete an invocation fails, then MicroSocketClientInvoker will make a number of attempts, according to the parameter "numberOfCallRetries", with a default value of 3. Once the configured number of retries has been exhausted, an org.jboss.remoting.InvocationFailureException will be thrown. */ clientMetadata.put("numberOfCallRetries", "1"); // Indicated the max number of threads used within oneway thread pool. clientMetadata.put(Client.MAX_NUM_ONEWAY_THREADS, "10"); clientMetadata.put(Remoting.USE_CLIENT_CONNECTION_IDENTITY, "true"); callbackClient = new Client(clientLocator, "callback", clientMetadata); Map listenerMetadata = new HashMap<>(); if (debugMode) { // prevent client from disconnecting while debugging listenerMetadata.put(ConnectionValidator.VALIDATOR_PING_PERIOD, "1000000"); listenerMetadata.put(ConnectionValidator.VALIDATOR_PING_TIMEOUT, "900000"); } else { listenerMetadata.put(ConnectionValidator.VALIDATOR_PING_PERIOD, "10000"); listenerMetadata.put(ConnectionValidator.VALIDATOR_PING_TIMEOUT, "9000"); } callbackClient.connect(new ClientConnectionListener(), listenerMetadata); Map callbackMetadata = new HashMap<>(); callbackMetadata.put(Bisocket.IS_CALLBACK_SERVER, "true"); if (callbackHandler == null) { callbackHandler = new CallbackHandler(); } callbackClient.addListener(callbackHandler, callbackMetadata); Set callbackConnectors = callbackClient.getCallbackConnectors(callbackHandler); if (callbackConnectors.size() != 1) { logger.warn("There should be one callback Connector (number existing = " + callbackConnectors.size() + ")"); } callbackClient.invoke(null); this.sessionId = callbackClient.getSessionId(); boolean registerResult; if (connection.getPassword() == null) { UserDataView userDataView = new UserDataView(connection.getAvatarId(), connection.isShowAbilityPickerForced()); // for backward compatibility. don't remove twice call - first one does nothing but for version checking registerResult = server.registerClient(connection.getUsername(), sessionId, client.getVersion()); if (registerResult) { server.setUserData(connection.getUsername(), sessionId, userDataView); } } else { registerResult = server.registerAdmin(connection.getPassword(), sessionId, client.getVersion()); } if (registerResult) { sessionState = SessionState.CONNECTED; serverState = server.getServerState(); if (!connection.getUsername().equals("Admin")) { updateDatabase(); } logger.info("Connected as " + (this.getUserName() == null ?
