Inbound channel not working in Spring - spring

Question

I am trying to copy a file from FTP and want to place it in local machine.
For this I created an inbound channel configurations are:
<bean name="publishStockSessionFactory"
class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
<property name="host"
value="10.255.255.1" />
<property name="port" value="21" />
<property name="username"
value="test" />
<property name="password"
value="test" />
</bean>
<bean id="stockLocalDirectory" class="java.lang.String">
<constructor-arg
value="/opt/test" />
</bean>
<bean id="stockRemoteDirectory" class="java.lang.String">
<constructor-arg
value="stock" />
</bean>
<int-ftp:inbound-channel-adapter
local-directory="# {stockLocalDirectory}"
channel="stockFilesFromFTP"
session-factory="publishStockSessionFactory"
remote-directory="#{stockRemoteDirectory}"
delete-remote-files="true"
filename-regex="Stock*.csv" >
<int:poller fixed-rate="120000" max-messages-per-poll="100" />
</int-ftp:inbound-channel-adapter>
<int:publish-subscribe-channel id="stockFilesFromFTP" />
And the error coming while start up is
INFO | jvm 1 | main | 2013/01/15 22:20:02.715 | 2013-01-15 22:20:02,699
ERROR task-scheduler-4 ErrorHandler : failed to send message
to channel 'stockFilesFromFTP' within timeout: -1
Debugs we turned on are
log4j.logger.org.springframework.aop=DEBUG
org.springframework.integration.channel.DirectChannel=DEBUG
org.springframework.integration.channel.MessagePublishingErrorHandler=DEBUG
org.springframework.integration.config.xml.PointToPointChannelParser=DEBUG
Can you suggest me how I can debug this error?

Answer 1

Run with DEBUG level logging.
You must have at least one subscriber on channel stockFilesFromFTP.

Answer 2

I used following kind of configuation for FTPclientfactory bean. It has timeout param also, so in case you are facing issue due to connection time out , this will help you.
<bean id="testapp.standardFTPClientFactory" class="org.springframework.integration.ftp.DefaultFTPClientFactory"
abstract="true">
<property name="host" value="${ftp.host}"/>
<property name="username" value="${ftp.username}"/>
<property name="password" value="${ftp.password}"/>
<property name="port" value="${ftp.port}"/>
<property name="remoteWorkingDirectory" value="${ftp.remotedir}"/>
<property name="dataTimeout" value="3600000"/>
<property name="connectTimeout" value="${ftp.connectTimeout}"/>
<property name="clientMode" value="2"/>
</bean>
