Q: how to set logging visible for replication

The producer/master mainly logs on debug level unless something bad or unexpected happens. Update log4j.xml with the following lines:

<category name="org.exist.replication" additivity="false">
  <priority value="debug"/>
  <appender-ref ref="console"/>
  <!-- <appender-ref ref="exist.core"/> -->
</category>

Q: My queries stopped working with v0.9.0

With the v0.9.0 pre-release the java-packages have been updated making them more logical and consistent. It makes the code better maintainable. Apologies for any inconvenience.

Replication:

<trigger class="org.exist.jms.replication.publish.ReplicationTrigger">
<trigger class="org.exist.jms.replication.subscribe.StartupTrigger">

import module namespace replication="http://exist-db.org/xquery/replication" 
              at "java:org.exist.jms.xquery.ReplicationModule"; 

Messaging:

import module namespace messaging="http://exist-db.org/xquery/messaging" 
              at "java:org.exist.jms.xquery.MessagingModule";

JMS receiver management:

import module namespace jms="http://exist-db.org/xquery/jms" 
              at "java:org.exist.jms.xquery.JmsModule";
