title: Java Service Wrapper cannot find main class
body: <p>Java Service Wrapper is the tools I need to run as a Windows service but came into a problem with <code>java.lang.ClassNotFoundException</code></p>
  
  <p>My default command line is: java -jar software.jar</p>
  
  <p>I have update the <code>wrapper.conf</code> for running <code>software.jar</code> located in D:\ and there was an error, the changes I have made:</p>
  
  <pre><code># Java Classpath (include wrapper.jar)  Add class path elements as
  #  needed starting from 1
  wrapper.java.classpath.1=../software.jar
  wrapper.java.classpath.2=../lib/wrapper.jar
  </code></pre>
  
  <p>and what should I put for this parameter? If I comment out, it would use <code>Main</code> class</p>
  
  <pre><code>wrapper.java.mainclass=software
  </code></pre>
  
  <p>As I declare "software" as the main class, I got the dread error:</p>
