Best way to connect to HEC with Java SDK

Question: What is the best way to connect to HEC with the Java SDK?

SDK JAR Version: 1.6.4.0

Currently, I am using the below code.

loginArgs.setToken("c0973521-5e90-4364-b551-cb7b1fcbfcf6");
loginArgs.setHost("https://hec.dev.splunk.domain.int:13510/services/collector/event");
loginArgs.setPort(13510);
HttpService.setSslSecurityProtocol(SSLSecurityProtocol.TLSv1_1);
Service service = Service.connect(loginArgs);

Which returns an error that the URI can't be null even though the host is being set, which leads me to believe that it's malformed.

java.lang.IllegalArgumentException: URI can't be null.

From what I'm seeing the setHost() argument should be the hostname or IP address only. I'm attempting to use the SDK to connect to HEC for the first time, I'll report back my success.

I wound up just writing a wrapper for cURL by leveraging Java's ProcessBuilder. Running into a tricky error where the same command is being executed in Java and Shell with different results. So perhaps they aren't the same.

You're using curl rather than using an HttpClient in java? That seems crazy.

So to be clear, you never did find a way to use the actual Splunk sdk to connect to an HEC?
