I am doing Spring Integration project. I'd like to publish XML string to one channel and receive Java object in other channel, via unmarshalling transformer.In my Spring config I am using these channels and beans:\[code\]<!-- channel to for publishing XML string --><int
ublish-subscribe-channel id="channels.pubsub.inXml" /><!-- channel for receiving transformed reply --><int:channel id="channels.fromXmlChannel"> <int:queue capacity="10" /></int:channel><!-- transformer unmarshalling XML to Java object --><int-xml:unmarshalling-transformer unmarshaller="marshaller" input-channel="channels.pubsub.inXml" output-channel="channels.fromXmlChannel" /><!-- marshaller bean --><bean id="marshaller" class="org.springframework.oxm.castor.CastorMarshaller" />\[/code\]I am trying this in unit test, so I have autowired channels to use:\[code\]@Autowired @Qualifier("channels.pubsub.inXml")MessageChannel inXmlChannel;@Autowired @Qualifier("channels.fromXmlChannel")MessageChannel fromXmlChannel;\[/code\]Trade class, which I want to have unmarshalled is very trivial POJO:\[code\]class Trade { String id; String direction; // getters, setters, constructors}\[/code\]Here's my JUnit test method, but I get exception on 3rd line:\[code\] @Testpublic void testUnmarshallingTransformer() { String xml = "<trade id='ID-01' direction='DIR-PRG' />"; Message<String> message = MessageBuilder.withPayload(xml).build(); inXmlChannel.send(message, TIMEOUT); Message<?> received = ((PollableChannel) fromXmlChannel).receive(TIMEOUT); System.out.println("\n\n" + received.getPayload());}\[/code\]And finally here's stacktrace:\[code\]org.springframework.integration.transformer.MessageTransformationException: failed to transform message at org.springframework.integration.transformer.AbstractTransformer.transform(AbstractTransformer.java:44) at org.springframework.integration.transformer.MessageTransformingHandler.handleRequestMessage(MessageTransformingHandler.java:67) at org.springframework.integration.handler.AbstractReplyProducingMessageHandler.handleMessageInternal(AbstractReplyProducingMessageHandler.java:97) at org.springframework.integration.handler.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:73) at org.springframework.integration.dispatcher.BroadcastingDispatcher.invokeHandler(BroadcastingDispatcher.java:105) at org.springframework.integration.dispatcher.BroadcastingDispatcher.dispatch(BroadcastingDispatcher.java:96) at org.springframework.integration.channel.AbstractSubscribableChannel.doSend(AbstractSubscribableChannel.java:61) at org.springframework.integration.channel.AbstractMessageChannel.send(AbstractMessageChannel.java:157) at sk.xorty.transformers.BuiltinTransformersTest.testUnmarshallingTransformer(BuiltinTransformersTest.java:190) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:74) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:83) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:72) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:49) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.junit.runner.JUnitCore.run(JUnitCore.java:157) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:76) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:195) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:63) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120)Caused by: org.springframework.oxm.UnmarshallingFailureException: Castor unmarshalling exception;
