This may help someone who wants to setup active mq auto discovery on EC2.=
=20

*Active-MQ Broker configuration:*

1. In $ACTIVEMQ_HOME/webapps folder create a new folder=20

|_activemq
      |_WEB-INF
             |_classes
             |_web.xml


create a web.xml file with the following contents

    &ltweb-app>

    =09&ltdisplay-name>ActiveMQ Message Broker Web
Application&lt/display-name>
    =09&ltdescription>
    =09=09Provides an embedded ActiveMQ Message Broker embedded inside a we=
b
application
    =09&lt/description>

    =09&lt!-- context config -->
    =09&ltcontext-param>
        =09&ltparam-name>org.apache.activemq.brokerURL&lt/param-name>
        =09&ltparam-value>tcp://localhost:61617&lt/param-value>
        =09&ltdescription>The URL that the embedded broker should listen on=
 in
addition to HTTP&lt/description>
    =09&lt/context-param>
    =09&lt!-- servlet mappings -->
      =09&ltservlet>
        =09&ltservlet-name>DiscoveryRegistryServlet&lt/servlet-name>
       =20
&ltservlet-class>org.apache.activemq.transport.discovery.http.DiscoveryRegi=
stryServlet&lt/servlet-class>
        =09&ltload-on-startup>1&lt/load-on-startup>
      =09&lt/servlet>
   =20
      =09&ltservlet-mapping>
        =09&ltservlet-name>DiscoveryRegistryServlet&lt/servlet-name>
        =09&lturl-pattern>/*&lt/url-pattern>
  =09&lt/servlet-mapping>
    &lt/web-app>

2. Place **httpclient-4.0.3.jar, httpcore-4.3.jar, xstream-1.4.5.jar and
activemq-optional-5.6.0.jar** in  **$ACTIVEMQ_HOME/lib** directory.

3. In* $ACTIVEMQ_HOME/config* directory, modify the *jetty.xml* file to
expose activemq web app.


  =09&ltbean id=3D"securityHandler"
class=3D"org.eclipse.jetty.security.ConstraintSecurityHandler">
=09=09...
  =09 =09&ltproperty name=3D"handler">
            =09&ltbean id=3D"sec"
class=3D"org.eclipse.jetty.server.handler.HandlerCollection">
               =09=09&ltproperty name=3D"handlers">
=09=09=09=09...
=09=09=09=09...
=09=09=09=09&ltbean class=3D"org.eclipse.jetty.webapp.WebAppContext">
                                        &ltproperty name=3D"contextPath"
value=3D"/activemq" />
                                        &ltproperty name=3D"resourceBase"
value=3D"${activemq.home}/webapps/activemq" />
                                        &ltproperty name=3D"logUrlOnStart"
value=3D"true" />
                                        &ltproperty
name=3D"parentLoaderPriority" value=3D"true" />
=09=09=09=09=09...
=09=09=09=09=09...
 =09=09=09=09&lt/list>
               =09=09&lt/property>
            =09&lt/bean>
        =09&lt/property>
    =09&lt/bean>

4. Modify activemq.xml file in  $ACTIVEMQ_HOME/conf directory to use http
protocol

=09&ltbroker name=3D=E2=80=9DbrokerName=E2=80=9D>
=09...
=09 &ltnetworkConnectors>
=09      &ltnetworkConnector name=3D"default"
uri=3D"http://&ltloadbalancer_IP>:&ltlocadbalancer_Port>/activemq/Discovery=
RegistryServlet?group=3Dtest"/>
=09      &lt!--&ltnetworkConnector name=3D"default-nc"
uri=3D"multicast://default"/>-->
=09       &lt/networkConnectors>

=09=09&lttransportConnectors>
=09=09    &lttransportConnector name=3D"http" uri=3D"tcp://0.0.0.0:61618"
discoveryUri=3D"http://&ltloadbalancer_IP>:&ltlocadbalancer_Port>/activemq/=
test"/>
=09=09&lt/transportConnectors>
=09...
=09&lt/broker>

make sure that the broker names are unique. =E2=80=9Ctest=E2=80=9D in url i=
s the group name
of brokers.
Client configuration:
1. Keep  httpclient-4.0.3.jar, httpcore-4.3.jar, xstream-1.4.5.jar and
activemq-optional-5.6.0.jar in classpath of client
2. URL to be use by client=20


discovery:(http://&ltloadbalancer_IP>:&ltlocadbalancer_Port>/activemq/test)=
connectionTimeout=3D10000

here =E2=80=9Ctest=E2=80=9D is the group name.
