Subject [jira] [Commented] (DIRMINA-645) SslFilter should start initiating handshake from sesionCreated() rather than from onPostAdd()
Date Tue, 25 Sep 2012 13:35:07 GMT

    [ https://issues.apache.org/jira/browse/DIRMINA-645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462733#comment-13462733

Victor N commented on DIRMINA-645:

Hi Emmanuel,
how to use StartTLS with the changed SslFilter? 'session created' event will be missed (session
was already started), 'onPostAdd' should be used in this case. I was trying to override SslFilter.onPostAdd()
in MySslFilter class, but I can not call _private_ method 'initiateHandshake'.

> 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.
