Unable to use file queue in v3.0.1

[Phillip Odam]

Hi

Previously incorrectly submitted to server-dev, not trying to blast the
mailing list.

Haven't spotted the following being discussed. I'm early on in my
investigation but so far I'm having no luck using the file based queue
in v3.0.1.

Here's what I did to replace ActiveMQ with the file queue.

Extracted META-INF/org/apache/james/spring-server.xml from
james-server-app-3.0.1/lib/james-server-spring-3.0.1.jar and placed
META-INF/org/apache/james/spring-server.xml in the conf directory so
path to spring-server.xml, relative to james root is
conf/META-INF/org/apache/james/spring-server.xml

Then changed the line

<import resource="classpath:META-INF/spring/activemq-queue-context.xml"/>

to this

<import resource="classpath:META-INF/spring/file-queue-context.xml"/>

The var/store/queue folders are all created as expected indicating
successful change over to the file queue.

However after starting james and attempting to send a message, the
following exception is thrown... does anyone have the file queue working
in v3.0.1?

org.apache.james.queue.api.MailQueue$MailQueueException: Unable to
enqueue mail;
