To reiterate many similar responses to you already, if you go to github and clone the SplunkJavaLogging repo, then there is a splunkrestappender for the logback framework.
Look at the examples, docs and code.
SplunkJavaLogging is bundled with a build of the SDK in splunk.jar
I got it. I download your version of the sdk
Where do i locate the com.splunk.Receivers class for the Java splunk SDK. I cloned all the classes for the Java Splunk SDK from the github repository previously, but it doesn't contain the com.splunk.Receivers class.
