I have a simple Java Twitter bot built with twitter4j. I just need to have one Java class that runs nonstop and it should all be well. It runs fine locally, but is unable to run on Heroku for some reason.
Here's what it says when attempting to run:

Starting process with command
java -cp src/BotLottery.java
That doesn't look right to me. The classpath is empty. And it should be a .jar or a .class file. Not a .java file.
