title: kafka-run-class error could not find or load main class

  <p>I'm trying to run my own application (on Linux) using Kafka Streams. I was able to successfully follow the instructions on their page and run the WordCountDemo application. Now I'm trying to use my own app (right now it is the same code, but I plan on doing something else with it) and when I write the command <code>bin/kafka-run-class.sh com.zzz.WordCount</code> I get <code>Error: Could not find or load main class com.zzz.WordCount</code></p>
  
  <p>I have my own WordCount.java like the following</p>
  
  <pre><code>/opt/kafka_2.12-1.0.0/src/main/com/zzz/WordCount.java
  </code></pre>
  
  <p>Is there anything else I need to do with my own app in order to be able to run it with kafka streams on my machine? Thanks.</p>
