If you use ActiveMQ 5.x that ships with Camel 1.x and you upgrade it to use Camel 2.0 you can get an exception while starting.

ERROR: java.lang.RuntimeException: Failed to execute start task. Reason:
org.springframework.beans.factory.BeanDefinitionStoreException: Unrecognized

The reason is basically that the XML namespace changed in Camel 2.0 as explained below.

When Camel went from an activemq subproject to a top level apache project, they changed the URIs for their xml schemas to reflect this in Camel 2.0.

These will probably occur in the xsi:schemaLocation attribute of the top level beans tag (both) and in the xmlns attribute in the camelContext element (just the first).
