Here is an example of a SU deploymennt. The SU is only a zip of these two files:

xbean.xml
<beans xmlns:script="http://org.apache.servicemix/script/1.0"
       xmlns:lang="http://www.springframework.org/schema/lang"
       xmlns:test="urn:test">
  <script:exchangeProcessor service="test:groovy" endpoint="endpoint">
    <property name="helpers">
      <list>
        <ref bean="groovyExchangeHelper" />
      </list>
    </property>
    <property name="implementation" ref="groovyExchangeProcessor" />
  </script:exchangeProcessor>
  <script:exchangeHelper id="groovyExchangeHelper" singleton="true" />
  <lang:groovy id="groovyExchangeProcessor"
               script-source="classpath:GroovyExchangeProcessor.groovy">

  </lang:groovy>
</beans>

class GroovyExchangeProcessor implements ExchangeProcessor {

    @Property ScriptExchangeHelper exchangeHelper;

	def void start() {

	}

    def void process(MessageExchange exchange) {
    	def inputMessage = new SourceTransformer().toString(exchange.getInMessage().getContent());
    	println "Hello, I got an input message "+inputMessage;
    	NormalizedMessage out = exchange.createMessage();
        out.setContent(new StringSource("<world>hello</world>"));
        exchange.setMessage(out, "out");
        exchangeHelper.sendExchange(exchange);    	
    }
    
    def void stop() {
    	println "Stopping";
    }
