I am using one inbound channel for downloading files & then other outbound channel to upload files & i do not need any poller but dont know why i am getting this exception. Can someone please help me out in this issue. I am using spring 4.0.6 Integration and spring core 4.0.6.
Logtrace:

Well, looks like you must come back to the theory and understand difference between polling and event-listening.
From other side you should agree that SFTP is some kind of remote file system and there is really no any other way to download new files from there, unless polling. The rule is applied for the JDBC, when we'd like to read new records from the table and so on.
So, since we agreed that <int-sftp:inbound-channel-adapter> is exactly Polling Consumer, we must declare <poller>, implicitly or like a global one.
That's from the side of the existing design and your config on the matter.
From other side let us know what you mean with:
i do not need any poller
How are you going to download files from the SFTP?
Yes, actually <int-sftp:outbound-gateway> can do the stuff for you, but that is a bit different story...

Scenario : poll the database every 'n' seconds and retrieve list. Do some internal business validations.If validations are success only, send the retrieved list to an external system.Receive an acknowledgment response from that system(After receiving this,poller should send next list).Then perform some business operations like calling other systems where polling is not needed.
can any one tell me how this scenario can be handled?

Can anyone please help with this...I have created only PollerService.java and dont have any idea to implement executer channel and task executer
The <poller> does that for you by default if you use fixed-delay option and your downstream flow is single threaded (only DirectChannels). In that case the next polling task (in your case reading DB using JPA) won't be started until the finish of previous one and some time like fixed-delay. See PeriodicTrigger, BTW.
Regarding your "Then perform some business operations". You should just make the next channel after "Receive an acknowledgment response" as an ExecutorChannel to free the polling Thread for the next poll.
You should really read more in the Spring Integration Reference Manual and especially about the Poller.
how to import Java Config bean in XML Config?
I try to create sample like this :
package com.fanjavaid.javaconfig;
...
#Configuration
public class CDConfig {
#Bean

}
}

Example that I made to follow the book Spring in Action.
What's the solution?
Thank you very much. :)
According to M.Denium answer, it works now.
Just add :
<context:annotation-config />
in Spring XML Configuration. So, it will looks like this :

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

this mostly happen because on some what you run the application on the server before. due to this it is unable to create the bean. so, as far as my understanding, in my case when i face this problem i go to the tomcat option or any server option and reset the deployment time to a longer one. for instance tomcat will undeploy any instance of the application and restart again if you provide the time need to do this job.
my advice is when ever you run the application you need to make sure that you undeploy the earlier run and also stop the server so that it automatically start by itself.
i hope this will help

As I understood from documentation there are a few properties which are responsible for allowed connections number (default combination of them allow 50 connections per node). They could be configured with Spring: connections-per-host and threads-allowed-to-block-for-connection-multiplier. I tried to use first one as shown below:
<mongo:mongo host="${mongo.db.host}" port="${mongo.db.port}">
<mongo:options connections-per-host="100"/>
</mongo:mongo>
But result is the same. I still get that exception about 50 allowed connections.
I would be very grateful if somebody could explain what I did wrong. Has anyone encountered this problem?

Ok. If its a normal bean then most likely you are just missing the xml parser for the scope tag. To be able to use scoped proxies you need to register aop:scoped-proxy.
There is a similar question on SO:
Accessing a session-scoped bean inside a controller
Which results in:
http://static.springsource.org/spring/docs/3.0.x/reference/beans.html#beans-factory-scopes-other-injection
Else you should easily find some tutorials on this topic through google.
It is likely that you have a bean-scoped option outside the bean (I made such mistake and got an error msg like yours) :
<beans>
...
<aop:config proxy-target-class="true"/>
<aop:scoped-proxy proxy-target-class="true"/>
<aop:aspectj-autoproxy proxy-target-class="true"/>
...
Just put that option inside of the bean declaration:
<bean ... target="step">
<aop:scoped-proxy proxy-target-class="true"/>
</bean>
One more thing - I got such error only for scoped beans.
