BTW I've just added a test case to the activemq-core module to test
this use case out...
https://svn.apache.org/repos/asf/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/camel/SetHeaderTest.java
Incidentally in the Java DSL you'd do this via code like this using
some kinda expression...
from("activemq:test-input").
setHeader("JMSXGroupID").el("${in.body}").
to("activemq:test-output");
or thanks to https://issues.apache.org/activemq/browse/CAMEL-348 you
can do it even easier...
from("activemq:test-input").
setHeader("JMSXGroupID").body().
to("activemq:test-output");
Its just we don't yet support the <setHeader> element in XML
