Remote adapter not connecting with my LS client in React native

rvkvino

I have used below code to connect the LS client with LS server, but this always saying connection status as disconnected , this I have tried by using react native as client and java remote adapter,
title: chenge URL and add confige to lightStreamer with react native / my lightStreamer status is DISCONNECTED after change URL and add user name confige Although i did change in (stockList,ADAPTER_SET,DATA_ADAPTER,FIELDS) and i chenged setupLightstreamerItemsSubscription function to

setupLightstreamerItemsSubscription() { const myClient= new LightstreamerClient(Constant.SERVER_ADDRESS, Constant.ADAPTER_SET) myClient.connectionOptions.setHttpExtraHeaders({"username": "lmxwinbullliteapp"}) myClient.connectionOptions.setHttpExtraHeadersOnSessionCreationOnly(true) /* React class instance reference */ const that= this; myClient.addListener({ onStatusChange : function(newStatus) { console.log(newStatus); var splittedStatus= newStatus.split(':'); that.setState({ status: splittedStatus.length=== 2? Constant.STATUS_DECODE[splittedStatus[1]]: splittedStatus[0]}); } }); myClient.connect(); // return myClient-+ const mySubscription= new Subscription("MERGE", Constant.ITEMS, Constant.FIELDS); mySubscription.setDataAdapter(Constant.DATA_ADAPTER); mySubscription.setRequestedSnapshot("yes"); mySubscription.addListener({ onSubscription : function() { console.log("SUBSCRIBED"); }, onUnsubscription : function() { console.log("UNSUBSCRIBED"); }, onItemUpdate : function(obj) { console.log("UPDATE FOR " + obj.getValue("stock_name")); that.updateState(obj) } }); myClient.subscribe(mySubscription); } componentDidMount() { this.eventEmitter= newEventEmitter(); this.setupLightstreamerItemsSubscription(); }

Hi rvkvino,

Could you get more details on the reason for the refusal to open a new session for the client?
You could go through the server log, lightstreamer.log, looking for any refusal message, or you could add to the ClientListener of to the client code to log onServerError events to the console as well (https://sdk.lightstreamer.com/ls-web-client/8.0.3/api/ClientListener.html#onServerError).

In fact, a possible problem could be that the remote adapters are not actually connected and therefore not available.

Regards,
Giuseppe
