title: How to run binary/exe that's part of a Java Web Application deployed on HEROKU?
body: <p>I have a Dynamic Web Project, developed with Eclipse, converted in a Maven project.</p>
  
  <p>I have exported the WAR, and i have deployed it on HEROKU.</p>
  
  <p>The issue is :</p>
  
  <pre><code>java.io.IOException: Cannot run program "/app/target/tomcat.21601/webapps/expanded/lib/binary": error=13, Permission denied
  </code></pre>
  
  <p>This binary is called by the servlet for doing some stuffs, but maybe it needs chmod command.</p>
  
  <p>From the Heroku console, I can't find a way to reach the binary and run chmod, cause the WAR is not a directory. </p>
  
  <p>How I can chmod a binary that is part of Web application, on the Heroku machine?</p>
