I think there are some subtle mechanism. JMSRemotingConnection public void start() | Map config = new HashMap(); | | config.put(Client.ENABLE_LEASE, String.valueOf(clientPing)); | | if (serverLocator.getParameters().containsKey(MicroSocketClientInvoker.MAX_POOL_SIZE_FLAG)) | { | throw new IllegalArgumentException("Invalid remoting configuration - do not specify clientMaxPoolSize" + | " use " + JBM_MAX_POOL_SIZE_KEY +" instead"); | } | | if (!serverLocator.getProtocol().equals("http") & !serverLocator.getProtocol().equals("https")) | { | String val = (String)serverLocator.getParameters().get(JBM_MAX_POOL_SIZE_KEY); | | if (val == null) | { | log.warn(JBM_MAX_POOL_SIZE_KEY + " not specified - defaulting to 200"); | | val = "200"; | } | | config.put(MicroSocketClientInvoker.MAX_POOL_SIZE_FLAG, val); | } | | client = new Client(serverLocator, config); | | client.setSubsystem("JMS"); | The method only set a few parameters of remoting,the Map config used as configuration of Client. The ConnectionValidator only use this map to set parameters,so it does not work. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4193655#...
