Subject [jira] [Commented] (ARTEMIS-1320) Unable to run REST on HA servers
Date Thu, 03 Aug 2017 15:52:01 GMT

    [ https://issues.apache.org/jira/browse/ARTEMIS-1320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16112979#comment-16112979
] 

Justin Bertram commented on ARTEMIS-1320:
-----------------------------------------

The current design only supports the REST servlet making an invm connection to an embedded
broker.  This won't work for HA setups as there will be a passive backup embedded with an
active Servlet container (Tomcat in this case).  I think the best way to solve this would
be to support using a tcp connection rather than an invm connection.  That way one could configure
a remote live/backup pair and a single container servicing HTTP requests could connect to
that live/backup pair.

> We are running Artemis in a Tomcat container and have enabled the REST API by configuring
 the web.xml as shown in the example.
> When we configure HA , the slaves fail to start with the following error from RestMessagingBootstrapListener.
The same also error happens on a fail back to the master node.
