How to configure the ActiveMQ 5.10.0 HawtIO interf

问题:

I'm using ActiveMQ 5.9.0 that has a amazing HawtIO interface. So when 5.10.0 has come, I migrated my system too. Now I see that the HawtIO interface doesn't exist inside it... It just disappeared from webapps folder from 5.9.0 to 5.10.0, so I tried the tutorial ActiveMQ and HawtIO but it doesn't work... How to configure the interface?

Alternatively, you can use HawtIO as a standalone web-app, that connects to ActiveMQ through Jolokia (pre 5.9 way of doing it).

1. Download the HawtIO standalone jar here: http://hawt.io/getstarted/index.html
2. Run the jar on the ActiveMQ-server: java -jar hawtio-app-1.4.37.jar (put the command in a .bat-script and add a scheduled task if you want it to run on startup..)
3. Navigate to http://your server:8080/hawtio
4. Create a new connection, give it a name, use localhost as host, 8161 as port and api/jolokia as path.

Connect, and enjoy!

As stated in Erik Williams answer:

• Unzip the hawt-io war into the ActiveMQ\webapps folder (ex. hawtio).

• change jetty.xml to include this webapp as a folder

  <bean class="org.eclipse.jetty.webapp.WebAppContext">
      <property name="contextPath" value="/hawtio" />
      <property name="resourceBase" value="${activemq.home}/webapps/hawtio" />
      <property name="logUrlOnStart" value="true" />
  </bean>
  

• On the default 5.10.0 standalone setup we also had to add three security paramaters to enable the brokers security. This can be done in the activmemq or activemq.bat file. Add these settings to the ACTIVEMQ_OPTS variable:

  • -Dhawtio.realm=activemq
  • -Dhawtio.role=admins
  • -Dhawtio.rolePrincipalClasses=org.apache.activemq.jaas.GroupPrincipal

• We did not have to remove the slf4j jar, it was not present.

Yeah I'm not entirely sure why they choose to do this, as it was a pretty big feature they'd been touting.

In any case, its pretty simple to set up yourself by downloading hawt-io itself and installing it as it was in 5.9 if you cannot get the stand alone method to work.

You'll need to decompress (or at least this is how I did it) the WAR and set up the jetty.xml as it was set up in 5.9 to include hawt.io as an application.

If I recall, I think I also ran into some class-loading conflicts due to some classes that come included with hawt.io that were newer than what was installed with the broker.
