I thought I had to declare the connection and channel inside the try block because exception need to be thrown or caught.

<br>> Yes, absolutely. The above looks like a scoping issue. I suspect you've done something like...

<br>> try {
<br>> final Channel channel = connection.createChannel();
<br>> doSomeWork(channel);
<br>> } finally {
<br>> channel.close();

<br>>
<br>> Am I right? If so, you need to move the channel variable to the outer scope.
