Gerald Kallas created KARAF-6773:
------------------------------------
Summary: ActiveMQ won't properly start in offline mode
Key: KARAF-6773
URL: https://issues.apache.org/jira/browse/KARAF-6773
Project: Karaf
Issue Type: Bug
Components: karaf
Affects Versions: 4.2.9
Reporter: Gerald Kallas
I've created a docker image based on Karaf 4.2.9 and ActiveMQ 5.15.13 (amongst
other features).
After embedding all features I enabled the offline mode for Karaf startup in
org.ops4j.pax.url.mvn.cfg as following
{code:java}
#
# If set to true, no remote repository will be accessed when resolving artifacts
#
org.ops4j.pax.url.mvn.offline = true
{code}
When starting in offline mode there's an error
{code:java}
...
Caused by: org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the
declaration of element 'beans'.

{code}
I created a workaround as described in
https://issues.apache.org/jira/browse/KARAF-6616
{code:java}
Temporary solution : Update the etc/activemq.xml root element which has been
provided by the feature installation like this
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.springframework.org/schema/beans
file:spring-beans-4.3.xsd
http://activemq.apache.org/schema/core
http://activemq.apache.org/schema/core/activemq-core.xsd";>
and provided the spring-beans-4.3 at ${KARAF_HOME}. Than the instance was able
to start again.
{code}
The error was gone in Karaf 4.2.8 but occured again in Karaf 4.2.9.
