That syntax will only work for ActiveMQ 4.1. Sounds like you may be
using 4.0.1. 
In that case, the persistence adapter configuration would look like
this:

    <persistenceAdapter>
        <kahaPersistentAdaptor dir="../activemq-data"/>
    </persistenceAdapter> 

Notice it is spelled kahaPersistentAdaptor. I don't think there is an
equivalent of the maxDataFileLength attribute.

Subject: Kaha Persistence question

Hello there I tried to enable Kaha persistence as described on the
how-tos:

 <persistenceAdapter>
      <kahaPersistenceAdapter dir = "activemq-data" maxDataFileLength =
"33554432"/>
    </persistenceAdapter>



But I'm getting this error:

Loading message broker from: xbean:activemq.xml
ERROR: java.lang.RuntimeException: Failed to execute start task.
Reason: org.springframework.beans.factory.BeanDefinitionStoreException:
Error registering bean with name '' defined in class path resource

Any ideas?

Regards
