我必须使用ESB Task(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.

I have to send XML message to my jms proxy service (service receive and send back message over JMS) with ESB Task (scheduler). I tried 2 solutions.

1个解决方案

在添加的任务中，我填写:

In added task I fill:

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

结果是，我的jms代理收到了消息，但没有JMS_Corelation(我想消息是在ESB中本地发送的)，并且出现了该错误:

The result is that, my jms proxy receive the message but without JMS_Corelation (I guess the message is send local in ESB) and I get that error:

Unexpected error sending message back org.apache.axis2.AxisFault: Transport out has not been set at org.apache.axis2.engine.AxisEngine.send(AxisEngine.java:432) at org.apache.synapse.core.axis2.Axis2Sender.sendBack(Axis2Sender.java:163) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.send(Axis2SynapseEnvironment.java:321) at org.apache.synapse.mediators.builtin.SendMediator.mediate(SendMediator.java:94) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) at org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:255) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.mediateFromContinuationStateStack(Axis2SynapseEnvironment.java:556) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.injectMessage(Axis2SynapseEnvironment.java:198) at org.apache.synapse.core.axis2.SynapseCallbackReceiver.handleMessage(SynapseCallbackReceiver.java:488) at org.apache.synapse.core.axis2.SynapseCallbackReceiver.receive(SynapseCallbackReceiver.java:170) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:180) at org.apache.axis2.transport.local.LocalResponder.handleResponse(LocalResponder.java:214) at org.apache.axis2.transport.local.LocalResponder.invoke(LocalResponder.java:111) at org.apache.axis2.engine.AxisEngine.send(AxisEngine.java:442) at org.apache.synapse.core.axis2.Axis2Sender.sendBack(Axis2Sender.java:163) at org.apache.synapse.mediators.builtin.RespondMediator.mediate(RespondMediator.java:23) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) at org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:255) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.mediateFromContinuationStateStack(Axis2SynapseEnvironment.java:556) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.injectMessage(Axis2SynapseEnvironment.java:198) at org.apache.synapse.core.axis2.SynapseCallbackReceiver.handleMessage(SynapseCallbackReceiver.java:488) at org.apache.synapse.core.axis2.SynapseCallbackReceiver.receive(SynapseCallbackReceiver.java:170) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:180)

如果我将此消息发送到队列中，则所有工作流程都可以正常工作，因此配置合理.

If I send this message to queue, all workflow works fine, so it is well configure.

2个解决方案

在添加的任务中，我填写:

In added task I fill:

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

结果是，由于没有任何反应，因此没有结果.我的jms代理服务没有收到任何消息.

The result is that, there is no result becasue nothing is happend. My jms proxy service doesn't receive any message.

有人知道该如何解决? 也许还有另一种方法可以做到这一点?

Someone knows how to fix that? Maybe there is another way to do that?

推荐答案

您的JMS代理配置为从JMS队列或主题接收消息.

Your JMS Proxy is configured to receive messages from a JMS queue or topic.

您应该尝试编写一个命名序列，该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:

You should try to write a named sequence that send an appropriate message into your queue or topic. Then, configure your scheduled task to call this sequence :
