Issue
When trying to make a connection back to the Contrast UI using the SDK, the following error is thrown:
Exception in thread "main" java.net.ConnectException: Connection refused
Cause
This error is commonly thrown when you specify an incorrect apiUrl.
Resolution
SaaS customers do not need to explicitly specify the API url because it will use the default. However, on-premise customers should check to verify that the full URL is being specified to the Contrast API. For example:
String apiUrl = "http://localhost:19080/Contrast/api";
