WSO2 ESB 任务（调度程序）不起作用

Question

我必须使用 ESB 任务（调度程序）将 XML 消息发送到我的 jms 代理服务（服务通过 JMS 接收和发送回消息）。 我尝试了 2 种解决方案。

1 个解决方案

在我填写的添加任务中：

message -> my XML
injectTo -> set 'proxy'
proxyName -> my proxy name

结果是，我的 jms 代理接收到消息但没有 JMS_Corelation（我猜消息是在 ESB 中本地发送的）并且我收到了该错误：

如果我将此消息发送到队列，则所有工作流程都可以正常工作，因此配置良好。

2个解决方案

在我填写的添加任务中：

message -> my XML
to -> my jms endpoint
format -> message format

结果是，没有结果，因为什么都没发生。我的 jms 代理服务没有收到任何消息。

有人知道如何解决这个问题吗？ 也许还有其他方法可以做到这一点？

您的 JMS 代理配置为从 JMS 队列或主题接收消息。

您应该尝试编写一个命名序列，将适当的消息发送到您的队列或主题中。然后，配置您的计划任务以调用此序列：

• injectTo = 序列
• format = soap11（例如）
• soapAction = mySoapAction（如果需要）
• 消息 = <root>myMessage</root>
• sequenceName = YourSequenceThatSendTheMessageToJMS
