title: Java Security Class Couldn't be found
body: <p>When launching my program the next error pops out</p>
  
  <blockquote>
    <p>java.lang.NoClassDefFoundError: Could not initialize class javax.crypto.SunJCE_b</p>
  </blockquote>
  
  <p>which means this class is missing although I've found this class manually, works via jar/ide but doesn't works prefectly via service.</p>
  
  <p>Maybe I need to make a few modifications? but which?
  Thanks in advance</p>
