spring integration spring-integration-2.1.0.RC1

[sset]

Hello,

1. Kindly let me know about a good link explains about channels, service activators, inbound - outbound with sample configurations.

2. While trying sample code for spring integration gives an error of "no such method" - looks like some jar is missing - not suire which one. Added all jars which comes with download of spring integration spring-integration-2.1.0.RC1.

code is below

public class HelloWorldApp {

private static Logger logger = Logger.getLogger(HelloWorldApp.class);

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext(
"dd/helloworlddemo.xml");
MessageChannel inputChannel = (MessageChannel) context.getBean(
"inputChannel", MessageChannel.class);
PollableChannel outputChannel = (PollableChannel) context.getBean(
"outputChannel", PollableChannel.class);
inputChannel.send(new GenericMessage<String>("World"));
logger.info("==> HelloWorldDemo: "
+ outputChannel.receive(0).getPayload());
}

}

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

http://www.springframework.org/schem...ring-beans.xsd
http://www.springframework.org/schema/integration
http://www.springframework.org/schema/integration/spring-integration.xsd">


<channel id="inputChannel"/>

<channel id="outputChannel">
<queue capacity="10"/>
</channel>

<service-activator input-channel="inputChannel"
output-channel="outputChannel"
ref="helloService"
method="sayHello"/>

<beans:bean id="helloService" class="com.hcl.sprngintg.HelloService"/>

</beans:beans>


3. Any example which has inbound as file with polling and outbound as JMS message or webservice message will be great.


Thanks

(4) how does service activator work?? What is the difference between gateway and adapter???


thanks

1. The reference manual is an excellent source of information you'll need

2. The github link for the samples has numerous samples which can help you understand things better.

3. Regarding the exception, what version of spring are you using?

4. While posting, post all you code between the [ CODE ] [/ CODE ] (without the spaces) tags

[sset]

Amol,

Answer to your point (3)
3. Regarding the exception, what version of spring are you using?
Jars used ->
spring-integration-core-2.1.0.RC1.jar
spring-integration-file-2.1.0.RC1.jar
commons-logging-1.0.4.jar
spring.jar - ver 3.x

Kindly let me know correct combination/versions of jars to be used.


Query -> How does integration between inbound and outbound channel happen? Is it using service activator? Apologies if my question is basic. My doubt we specify different channels for inbound / outbound but still message flow.

Thanks

Amol please find stubs giving exception (nosuchmethod) with above jars
Please try from your side and let us know.

Looking at your exception I am not sure that your are using Spring 3.x. In fact the exception tells me that you are using Spring 2.5.x since version 3.0 of RootBeanDefinition definitely has a constructor that takes String. So you might be using the wrong version of Spring or you may have two versions on the classpath
