我正在尝试使用 Jboss 7.3.0 和 activemq-rar-5.6.0 设置嵌入式 activeMQ。嵌入式代理应该可以从 Jboss 内部和外部访问（通过来自另一个应用程序的 tcp）
当我使用“standalone.bat -c Standalone-full.xml”启动 jboss 时，我面临以下异常
**Caused by: org.jboss.msc.service.DuplicateServiceException: Service jboss.ra.activemq-ra is already registered**
我真的很感激任何关于我为什么会得到这个例外的指导。我在日志中附上了一张图片。
下面是我的配置。
我在standalone-full.xml 文件中的资源适配器子系统中添加了一个资源适配器
<subsystem xmlns="urn:jboss:domain:resource-adapters:5.0">
<resource-adapters>
<resource-adapter id="activemq-ra.rar">
<archive>
activemq-ra.rar
</archive>
<transaction-support>XATransaction</transaction-support>

<config-property name="PhysicalName">HELLOWORLDMDBTopic</config-property>
</admin-object>
</admin-objects>
</resource-adapter>
</resource-adapters>
</subsystem>
我更新了standalone-full.xml 文件中mdb 标记内的resource-adapter-ref。
<subsystem xmlns="urn:jboss:domain:ejb3:6.0">
<session-bean>
<stateless>
<bean-instance-pool-ref pool-name="slsb-strict-max-pool"/>
</stateless>
<stateful default-access-timeout="5000" cache-ref="simple" passivation-disabled-cache-ref="simple"/>
<singleton default-access-timeout="5000"/>
</session-bean>
<mdb>
<!--<resource-adapter-ref resource-adapter-name="${ejb.resource-adapter-name:activemq-ra.rar}"/> -->
<resource-adapter-ref resource-adapter-name="activemq-ra.rar"/>
<bean-instance-pool-ref pool-name="mdb-strict-max-pool"/>
</mdb>
Standalone-full.xml 中的消息传递子系统是
<subsystem xmlns="urn:jboss:domain:messaging-activemq:8.0">
<server name="default">
<statistics enabled="${wildfly.messaging-activemq.statistics-enabled:${wildfly.statistics-enabled:false}}"/>

</server>
</subsystem>
我更新了 ra.xml 文件，将 ServerUrl 更改为 tcp://localhost:61616
<resourceadapter-class>org.apache.activemq.ra.ActiveMQResourceAdapter</resourceadapter-class>
<config-property>
<description>
The URL to the ActiveMQ server that you want this connection to connect to. If using
an embedded broker, this value should be 'vm://localhost'.
</description>
<config-property-name>ServerUrl</config-property-name>
<config-property-type>java.lang.String</config-property-type>
<config-property-value>tcp://localhost:61616</config-property-value>
<!--<config-property-value>vm://localhost</config-property-value> -->
</config-property>
并将 META-INF/ra.xml 中的 config-property BrokerXmlConfig 的 config-property-value 设置为 xbean:broker-config.xml
<config-property>
<description>
Sets the XML configuration file used to configure the embedded ActiveMQ broker via
Spring if using embedded mode.
BrokerXmlConfig is the filename which is assumed to be on the classpath unless
a URL is specified. So a value of foo/bar.xml would be assumed to be on the
classpath whereas file:dir/file.xml would use the file system.
Any valid URL string is supported.
</description>
<config-property-name>BrokerXmlConfig</config-property-name>
<config-property-type>java.lang.String</config-property-type>
<config-property-value></config-property-value>
<description>To use the broker-config.xml from the root for the RAR </description>
<config-property-value>xbean:broker-config.xml</config-property-value>
<!-- To use an external file or url location
<config-property-value>xbean:file:///amq/config/jee/broker-config.xml</config-property-value>
-->
</config-property>
我创建了一个新的 activemq-ra.rar 文件并将其放在 jboss-eap-7.3\standalone\deployments 文件夹中。
