I am not able to download the file from ftp server when it is TLS authenticated. I have used the DefaultFtpsSessionFactory session for TLS authentication.EveryTIme polling is started "ERROR DURING HANDSHAKE OCCURS".

Although i am able to download file using FTPSClient of apache.common.net through normal java class.

my xml config is like :-

<bean id="ftpClientFactory"
        class="org.springframework.integration.ftp.session.DefaultFtpsSessionFactory">
        <property name="host" value="52.172.153.35"/>
        <property name="port" value="21"/>
        <property name="username" value=""/>
        <property name="password" value=""/>
        <property name="clientMode" value="2"/>
        <property name="bufferSize" value="100000"/>


<int-ftp:inbound-channel-adapter id="plannedFtpChannel" 
        session-factory="ftpClientFactory" filename-pattern="*.xls" local-filter="plannedFilter" auto-startup="true"
        auto-create-local-directory="true" delete-remote-files="false" remote-directory="/planned" local-directory="/DataFiles/planned" >
        <int:poller fixed-delay="10000">
        </int:poller>
</int-ftp:inbound-channel-adapter>

I am Getting error like :-

taskScheduler-6, received EOFException: error taskScheduler-6, handling exception: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake %% Invalidated: [Session-4, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384] taskScheduler-6, SEND TLSv1.2 ALERT: fatal, description = handshake_failure

  • As was commented on [your other question which you just deleted](http://stackoverflow.com/questions/40676862/how-to-connect-through-ftp-with-tls-authentication-in-spring-integration-for-fil), see [this question/answer](http://stackoverflow.com/questions/32398754/how-to-connect-to-ftps-server-with-data-connection-using-same-tls-session). – Gary Russell Nov 21 '16 at 14:30
  • am not able to configure it with xml as it is suggested there.? – prince prakash Nov 21 '16 at 15:03
  • You need to explain what you mean. You need to create the customized session factory. – Gary Russell Nov 21 '16 at 18:03
  • I have created the customised session factory and overriden the method createClientInstance(), but still the same error persist; – prince prakash Nov 22 '16 at 06:11
  • Thanks for the input gary! Here we have to override the getSession() and createClient() of DefaultFtpssessionFactory also for achieving the customised FTPSClient.! Its working fine with this config. now! – prince prakash Nov 22 '16 at 11:26
