# How to Run the Sample
|
||||

If you imported the example into your IDE, you can just run class **org.springframework.integration.samples.amqp.Main**. For example in [SpringSource Tool Suite](http://www.springsource.com/developer/sts) (STS) do:

If you imported the example into your IDE, you can just run class **org.springframework.integration.samples.amqp.SampleSimple**. For example in [SpringSource Tool Suite](http://www.springsource.com/developer/sts) (STS) do:
|
||||
|
||||
* Right-click on Main class --> Run As --> Java Application
|
||||
* Right-click on SampleSimple class --> Run As --> Java Application
|
||||
|
||||
Alternatively, you can start the sample from the command line ([Gradle](http://www.gradle.org) required):
|
||||
Alternatively, you can start the sample from the command line:
|
||||
|
||||
* gradlew :amqp:run
|
||||
* ./gradlew :amqp:runSimple
|
||||
|
||||
Enter some data (e.g. 'foo') on the console; you will see a [tapInbound] log and 'Received: foo'.
|
||||
|
||||
Ctrl-C to terminate.
|
||||
|
||||
The __SamplePubConfirmsReturns__ class is similar, but demonstrates publisher confirms and returns.
|
||||
|
||||
* Right-click on SamplePubConfirmsReturns class --> Run As --> Java Application
|
||||
|
||||
Or:
|
||||
|
||||
* ./gradlew :amqp:runPubConfirmsReturns
|
||||
|
||||
When you enter a message in the console you will see the message received, together with a send confirmation:
|
||||
|
||||
````
|
||||
foo
|
||||
Received: foo
|
||||
foo sent ok
|
||||
````
|
||||
|
||||
When you enter 'fail', the message is sent with a bad routing key; you will see the message is sent ok, but returned because it is not routable:
|
||||
|
||||
````
|
||||
fail
|
||||
fail returned:NO_ROUTE
|
||||
fail sent ok
|
||||
````
|
||||
|
||||
When you enter 'nack', the message is sent to a non-existent exchange; the broker reacts to this by closing the channel with an error and Spring AMQP generates a Nack:
|
||||
|
||||
````
|
||||
nack
|
||||
nack send failed (nack)
|
||||
11:54:00.818 ERROR [pool-1-thread-1][org.springframework.amqp.rabbit.connection.CachingConnectionFactory] Channel shutdown: channel error; protocol method: #method<channel.close>(reply-code=404, reply-text=NOT_FOUND - no exchange 'badExchange' in vhost '/', class-id=60, method-id=40)
|
||||
````
|
||||
|
||||
Ctrl-C to terminate.
