mongodb outbound and specific channel

[poty]

Hi,

I'm trying to configure a queue channel with the mongodb outbound-channel-adapter this way:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:int="http://www.springframework.org/schema/integration"
	xmlns:int-mongodb="http://www.springframework.org/schema/integration/mongodb"
	xsi:schemaLocation="http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration-2.2.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/integration/mongodb http://www.springframework.org/schema/integration/mongodb/spring-integration-mongodb-2.2.xsd">

	<int:channel id="entriesChannel" >
        <int:queue/>
       </int:channel>
    
    <int-mongodb:outbound-channel-adapter id="deafultAdapter" channel="entriesChannel" collection-name="entry" mongo-template="mongoTemplate" />

</beans>

But I'm getting this xsd validation error:

Referenced file contains errors (http://www.springframework.org/schema/integration/spring-integration-2.2.xsd).  For more information, right click on the message in the Problems View and select "Show Details..."

Everything else is configured via java annotations (i.e. mongo configuration) because I was not able to find how to configure integration with java annotations and I'm loading this xml through:

@Configuration
@ImportResource("classpath:some/folder/integration.xml")
public class IntegrationConfig {
}

What am I doing wrong?
Is there any way to configure integration with java annotations?

Thanks!

See this thread for avoiding bogus validation warnings in STS.

Aside from this, when using a queue channel, you will either need a <poller/> child element on the adapter, or a global default poller.

Several efforts are underway to configure SI without XML (scala and groovy DSLs as well as a java builder mechanism). Some components already can be configured using annotations but currently not external endpoints such as mongo.

Search the TOC for 'Annotation'.

Thank you for your quick reply
I had followed your instructions but no luck, even changing workspace and import with explicitly setting the versions (and cleaning/rebuild the project)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:int="http://www.springframework.org/schema/integration"
    xmlns:int-mongodb="http://www.springframework.org/schema/integration/mongodb"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
		http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
		http://www.springframework.org/schema/integration
		http://www.springframework.org/schema/integration/spring-integration-2.2.xsd
		http://www.springframework.org/schema/integration/mongodb
		http://www.springframework.org/schema/integration/mongodb/spring-integration-mongodb-2.2.xsd">
 
    <int:channel id="entriesChannel">
        <int:queue />
    </int:channel>
    
    <int-mongodb:outbound-channel-adapter id="entriesMongoChAdapter" channel="entriesChannel">
    	<int:poller fixed-rate="30000" max-messages-per-poll="1" />
    </int-mongodb:outbound-channel-adapter>
 
</beans>

Now I'm getting this error in addition of the previous one:

Description	Resource	Path	Location	Type
cvc-complex-type.2.1: Element 'int-mongodb:outbound-channel-adapter' must have no character or element information item [children], because the type's content type is empty.

Well, that is definitely a bug; the adapter should allow a <polller/> child element. Please open a JIRA issue: https://jira.springsource.org/browse/INT

Is there any particular reason you are using a QueueChannel? If you want to asynchronously send to Mongo, you can use an ExcecutorChannel.

Every time I add in the same xml a channel tag (channel with or without queue or publish-subscribe-channel) and int-mongodb:outbound-channel-adapter tag I get the validation error

Referenced file contains errors (http://www.springframework.org/schema/integration/spring-integration-2.2.xsd).  For more information, right click on the message in the Problems View and select "Show Details..."

Details:

ct-props-correct.4: Error for type 'aggregator-type'. Duplicate attribute uses with the same name and target namespace are specified. Name of duplicate attribute use is 'release-strategy'

Could you confirm this? this is too odd...I don't know if my STS is messed up...

EDIT: omg my bad ...I thought spring-integration-core maven dependency will import everything else so I had not added spring-integration-mongodb...everything is working now, sry
