title: how to create installer for Java that copies dll to JRE folder
body: <p>I created a program and I want to make an installer for it.
  I have never done it before. Program uses <code>RXTXcomm.jar</code> and in order my program to work, some dll files has to be copied to JRE:</p>
  
  <p><code>rxtxSerial.dll</code> and <code>rxtxParallel.dll</code> to <code>&lt;JAVA_HOME&gt;\jre\bin</code></p>
  
  <p>so i wonder, how to make an installer that can copy these files?
  I tried "Inno Setup 5" but i can't find how to do that.
  I also tried "Advanced Installer" software, but can't figure it out so far.  </p>
