How do I connect my Java program to Splunkd server?

madhanbaskar — Mon, 16 Oct 2017 10:42:12 GMT

I'm using the below mentioned code in java:

import com.splunk.*; // The entry point to the client library
public class Connection
{
public static void main(String[] args)
{
ServiceArgs loginArgs = new ServiceArgs();
loginArgs.setUsername("admin");
loginArgs.setPassword("changeme");
loginArgs.setHost("apl10865gtapp14");
loginArgs.setPort(8089);
loginArgs.setScheme("http");
HttpService.setSslSecurityProtocol(SSLSecurityProtocol.TLSv1_2);
Service service = Service.connect(loginArgs);
for (Application app : service.getApplications().values())
{
System.out.println(app.getName());
}}}

Below mentioned is the error which I get....

Exception in thread "main" java.lang.RuntimeException: Connection refused: connect

Whilst I wont be any help with solving any Java issues, (I'm not a java dev) the management port on 8089 is https, but it looks like you are using an http scheme to connect.
Try using https: loginArgs.setScheme("https");

You probably don't have Firewall Permissions from were you run your code to your splunk instance on port 8089?

"Caused by: java.net.ConnectException: Connection refused: connect"

Have you validated (using telnet, maybe) that you have network connectivity between your source host and your target host apl10865gtapp14?

Because of : Caused by: java.net.ConnectException: Connection refused: connect

I am guessing firewall.
