FTPS: "Unrecognized SSL message, plaintext connection?. Code: 234"

[Andreas Asmuss <an...@gmail.com>]

Hi

I'm trying my hand at using FTP over SSL. At some point I'd like to use both
server and and client authentication via certificates. I have configured a
server that has a certificate. This works fine when I log into it using a
normal FTP client; the certificate pops up and I must accept it etc.

I've set up a route like this:

<route>
	<from
uri="ftps:192.168.1.48:21/download?username=dmr&amp;password=dmr123&amp;consumer.delay=5s&amp;securityProtocol=SSL&amp;isImplicit=false&amp;consumer.initialDelay=5000"
/>
	<to uri="file:test_data" />
</route>

Where I get this exception which I don't really know how to interpret:

2010-07-27 11:04:41,441 DEBUG [Camel Thread 0 -
ftps://192.168.1.48:21/download]

Will try to recover.
