Hi guys,
I’m new here, and I’m getting flumoxed by a simple hello world example. I’m using the stand alone compiler, and trying to compile a simple Kotlin program. I believe the following shell output describes everything. Notice the class not found error. I unpacked kotlin-runtime.jar, and there certainly seems to be a class that fits the description of the path that’s not being found, so I’m very confused. I usually don’t run things from the command line, so perhaps I’m just using Java incorrectly?
Any thoughts would be appreciated.

println(“Hello, world!”)

$ sh /tmp/kotlinc/bin/kotlinc-jvm hw.kt -jar hw.jar // it seems to compile just fine

$ java -cp /tmp/kotlinc/lib/kotlin-runtime.jar -jar hw.jar // run my brand new JAR, and use the Kotlin runtime
