A few things to check:

1) Do you have you class mapping set in activemq.xml, like

  <bean class="org.apache.activemq.util.XStreamFactoryBean" name="xstream">
                <property 
name="annotatedClass"><value>org.apache.activemq.transport.stomp.SamplePojo</value></property>
  </bean>

2) Do you have XStream dependency in your classpath?
