I have a table in dolphindb:

t = streamTable(30000:0,`id`time`sym`qty`price[INT,TIME,SYMBOL,INT,DOUBLE])
share t as Trades

And I want to subscribe this table in java client.

PollingClient client = new PollingClient(8892);
TopicPoller poller1 = client.subscribe("localhost", 8848, "Trades");

But it has errors as following：

  • most likely your 8892 is already occupied by some other process. have you tried with a different port or freeing up this port before running this above code? – shakhawat Feb 23 '20 at 17:01
