Question

我无法向activemq中的xmpp队列发送消息。我得到以下示例。根据我下载 wstx jar并放在activemq/lib/optional文件夹中的文档。

我得到以下异常：

Caught: javax.jms.JMSException: Could not create Transport. Reason: java.io.IOException: Transport scheme NOT recognized: [xmpp]

感谢任何帮助。

您需要将activemq-xmpp依赖项添加到maven pom.xml

  <dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-xmpp</artifactId>
<version>5.8.0</version>
 </dependency>

如果你没有使用maven，那么将activemq-xmpp.jar添加到/ lib与所有其他jar

无法将消息发送到activemq中的xmpp队列
