Emmanuel Lecharny commented on DIRMINA-645:
-------------------------------------------

You can fetch the SslFilter from the chain, and call the startSsl() method :
        LOG.info( "Handling StartTLS request." );

        IoFilterChain chain = session.getIoSession().getFilterChain();
        SslFilter sslFilter = ( SslFilter ) chain.get( "sslFilter" );
        if ( sslFilter == null )
        {
            sslFilter = new SslFilter( sslContext );
            chain.addFirst( "sslFilter", sslFilter );
        }
        else
        {
            sslFilter.startSsl( session.getIoSession() );
        }


This is what we do in ApacheDS.

Note that I'm not sure that it works if the SslFilter is not in the chain when 
the server is started...

> Here's the situation I needed to get working.  We want to make a secure 
> connection through a SOCKS 5 proxy.  So, one would think that just using the 
> SslFilter and and the ProxyConnector (which adds the ProxyFilter at the 
> bottom of the stack) would just do it.  Unfortunately, it does not work quite 
> right out of the box.  The ProxyFilter only fully initializes itself after 
> the sessionCreated() method is called.  Meanwhile, the SslFilter tries to 
> start the handshake (i.e. calls initiateHandshake()) from the onPostAdd() 
> method, which occurs before the sessionCreated() is called.
> Moving the initiateHandshake() from onPostAdd() to sessionCreated() in 
> SslFilter, as shown below, seems to fix the problem.
>     @Override
>     public void onPostAdd(IoFilterChain parent, String name,
>             NextFilter nextFilter) throws SSLException {
> //        if (autoStart) {
> //            initiateHandshake(nextFilter, parent.getSession());
> //        }
>     }
>     
>     @Override
>       public void sessionCreated(NextFilter nextFilter, IoSession session)
>                       throws Exception {
>       super.sessionCreated(nextFilter, session);
>       
>       if (autoStart) {
>             initiateHandshake(nextFilter, session);
>         }
>       }
