Java SDK Program Connection Reset

[Guangjie]

I created a first Java program with Splunk SDK and set scheme to "http". But I haven't this "Exception in thread "main" java.lang.RuntimeException: Connection reset".

ServiceArgs serviceArgs = new ServiceArgs();
serviceArgs.setUsername("admin");
serviceArgs.setPassword("password");
serviceArgs.setHost("192.168.1.88");
serviceArgs.setPort(8089);
serviceArgs.setScheme("http");
Service service = Service.connect(serviceArgs);
Args oneshotSearchArgs = new Args();
InputStream resultsStream = service.oneshotSearch("search index=_internal | head 5",oneshotSearchArgs);
