Using a "ref" attribute is generally recommended if the POJO consumer implementation can be reused
in other <code>&lt;outbound-channel-adapter&gt;</code> definitions. However if the consumer implementation
should be scoped to a single definition of the <code>&lt;outbound-channel-adapter&gt;</code>, you can define it as inner bean:
<programlisting language="xml"><![CDATA[<outbound-channel-adapter channel="channel2" method="method2">
<beans:bean class="org.bar.Foo"/>

</outbound-channel-adapter>

Using both the "ref" attribute and an inner handler definition in the same <code>&lt;outbound-channel-adapter&gt;</code>
configuration is not allowed, as it creates an ambiguous condition and will result in an Exception being thrown.

Any Channel Adapter can be created without a "channel" reference in which case it will implicitly create an
instance of <classname>DirectChannel</classname>. The created channel's name will match the "id" attribute
