KahaDb properties in Grails

Using ActiveMQ in Grails through JMS plugin I cannot figure how to set KahaDb persistence properties.

Tried something like:

amq.broker(useJmx: true, persistent: true) {
    amq.transportConnectors() {
        amq.transportConnector(uri: "tcp://0.0.0.0:61616")
    }
    amq.persistenceAdapter() {
        amq.kahaDB(directory:${application.config.grails.moviesxd.activemq.kahadb},
                   checksumJournalFiles:true,
                   checkForCorruptJournalFiles:true,
                   ignoreMissingJournalfiles:true)          
    }
}

But i get

groovy.lang.GroovyRuntimeException: Namespace prefix: kahadb is not bound to a URI

Seems like kahadb prefix is not recognized but i cannot find documentation anywhere on how to do this.

You're just missing the equivalent of

xmlns:amq='http://activemq.apache.org/schema/core'

which would be

xmlns amq:'http://activemq.apache.org/schema/core'

(see the reference docs for more info - search for "Using Spring Namespaces")

so the whole conversion would be

import org.springframework.jms.connection.SingleConnectionFactory

xmlns amq:'http://activemq.apache.org/schema/core'

amq.broker(useJmx: true, persistent: true) {
    amq.transportConnectors {
        amq.transportConnector(uri: 'tcp://0.0.0.0:61616')
    }
    amq.persistenceAdapter {
        amq.kahaDB(directory: application.config.grails.moviesxd.activemq.kahadb,
                   checksumJournalFiles: true,
                   checkForCorruptJournalFiles: true,
                   ignoreMissingJournalfiles: true)
    }
}

amq.connectionFactory(id: 'amqConnectionFactory', brokerURL: 'vm://localhost')

jmsConnectionFactory(SingleConnectionFactory, ref('amqConnectionFactory'))
