title: java.lang.NoClassDefFoundError: sun/security/util/DerValue
body: <p>My application is up on websphere and i keep seeing this error , due to which it sometime triggers 500 internal server error.</p>
  
  <p>The application needs 256 bit encryption and java by default does not provide the same. So i have used Sun JCE which is creating this problem in websphere.</p>
