title: Java DefaultSslContextFactory keystore update dynamically
body: <p>I have an existing application that uses the <code>org.restlet.engine.ssl.DefaultSslContextFactory</code> and a keystore file that is loaded when the server is started. 
  I have another application that creates certificates that have to be added
  dynamically to the keystore file while the server is running. To perform this,
  I created the certificate and the private key in the code and then write it
  to a directory. The directory is watched by a bash script that checks for new files, and if one appears it will be imported into the existing keystore file.</p>
  
  <p>But when trying to access the server with the newly imported certificate the handshake fails. Only when restarting the server, the access can be completed successfully, which I assume means that the added certificate will not be reloaded by the server.</p>
  
  <p>Is there a way to update the running application with the new entry in the keystore file?</p>
