Subject Re: XStream annotations for XML transformation
Date Tue, 17 Feb 2009 10:05:46 GMT
Hi Michael,

We can inject the configured xstream the transformer will use. For example,
for the SamplePojo used in tests we configure the xstream like this

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

so it get properly annotated.

I see now that they added autodetectAnnotations(), so I'll experiment with
it a bit.

Cheers
