title: Calling Java .jar Program from Perl using System()
body: <p>The title pretty much says it all, I am trying to get a java program (.jar file) to run from a Perl program.  I read another post on Stackoverflow saying this syntax is correct:</p>
  
  <pre><code>system("java filename.jar");
  </code></pre>
  
  <p>However this is giving me the following error.  I'm not sure if the problem is that it shows the filename as "filename/jar" instead of "filename.jar"</p>
  
  <pre><code>Exception in thread "main" java.lang.NoClassDefFoundError: filename/jar
  Caused by: java.lang.ClassNotFoundException: filename.jar
