[erlang-questions] Programming Erlang: Chap 18, Websockets

[Jesper Louis Andersen]

The error suggest the `ssl` application has not been started by something
depends on it. My bet is that a dependency was updated somewhere between
that code was written and your Erlang release, so things goes awry. If you
look at the line

{"init terminating in do_boot",{{badmatch,{error,{no
t_started,ssl}}},[{ezwebframe,start_link,2,[{file,"src/
ezwebframe.erl"},{line,22}]},{init,start_em,1,[]},{init,do_boot,3,[]}]}}

You have the stack of where the error occurred. The topmost frame is in
ezwebframe:start_link/2 (src/ezwebframe.erl:22). To fix the problem, this
is probably where you should look.
