Implementei o exercício e não há saída. Pode ser versão do Camel?

Olá. Implementei a seguinte rota:

final XStream xstream = new XStream();
xstream.alias("negociacao", Negociacao.class);
from("timer://negociacoes?fixedRate=true&delay=3s&period=360s")
        .to("http4://argentumws.caelum.com.br/negociacoes")
        .convertBodyTo(String.class)
        .unmarshal(new XStreamDataFormat(xstream))
        .split(body()).log("${body}").end();

Mas nada é impresso no Console do eclipse. Estou usando uma versão nova do camel e meu maven dependencies está assim:

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <camel.version>2.24.1</camel.version>
    </properties>

    <dependencies>

        </dependency>

        </dependency>

        <dependency>

            <artifactId>xom</artifactId>

        </dependency>

Alguma sugestão de mudança?
