以上是我的ejb-jar.xml文件。

以下内容来自standalone-full.xml

    <system-properties>  
          <!-- JMS properties for ejb-jar.xml -->  
           <property name="jms.queue.manager.channel"  value="QUEUE_MANAGER_CHANNEL"/>  
           <property name="jms.queue.manager.host"     value="QUEUE_MANAGER_HOST"/>  
           <property name="jms.queue.manager.name"     value="QUEUE_MANAGER_NAME"/>  
           <property name="jms.queue.manager.port"     value="QUEUE_MANAGER_PORT"/>  
           <property name="jms.queue.mymdb"            value="MYMDB_QUEUE"/>  
     </system-properties>

但是当我部署MDB或在使用MDB后重新启动服务器时，它会产生错误，即ejb-jar.xml无法读取目标，hostName等的值。他们是空的。我使用的是JBOSS 7.2.0。

我也确保使用standalone.bat -c standalone-full.xml启动jboss，因为我在这里放置了系统属性。

Answer 1

确保您的standalone-full.xml已启用spec-descriptor-property-replacement。此属性使jboss能够替换ejb-jar.xml等描述符中的属性值。

该物业位于

<subsystem xmlns="urn:jboss:domain:ee:1.1">
        <spec-descriptor-property-replacement>true</spec-descriptor-property-replacement>
        <jboss-descriptor-property-replacement>true</jboss-descriptor-property-replacement>
</subsystem>
