java.lang.ClassCastException

[ashleyvijay]

Hi, I get the following exception.What should I do to solve this error??Please help.I wonder whts with the "QueueChannel" in the exception??

Main Method:

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("SI.xml", GidSI.class);

// Compose the XML message according to the server's schema
String requestXml =
"<hr:CompanyRequest xmlns:hr=\"http://mycompany.com/hr/schemas\">" +
"<hr:Company>"+
"<hr:CompanyName>TestRequest</hr:CompanyName>"+
"</hr:Company>"+
"</hr:CompanyRequest>";

// Create the Message object
// In this case the service expects a SoapAction header
Message<String> message = MessageBuilder.withPayload(requestXml)
	.setHeader(AbstractWebServiceOutboundGateway.SOAP_ACTION_PROPERTY_KEY, "http://mycompany.com/hr/schemas")
		.build();
// Send the Message to the handler's input channel
((MessageChannel)context.getBean("sendChannel")).send(message);
	}
}

Exception:

Exception in thread "main" java.lang.ClassCastException: org.springframework.integration.channel.QueueChannel

Can you add SI.xml to the post?

[ashleyvijay]

SI.xml

<message-bus/>
<channel id="sendChannel"/>
<ws:outbound-gateway id="WebServiceGateway"
				         request-channel="sendChannel" 
				         reply-channel="WebServiceReceiveChannel"
				    uri="http://localhost:8080/Trial1/companyservice"/>

	
<jms:outbound-gateway request-channel="WebServiceReceiveChannel" connection-factory="connectionFactory" jms-queue="HelloQueue"/>
    
<beans:bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
		<beans:property name="targetConnectionFactory">
			<beans:bean class="org.apache.activemq.ActiveMQConnectionFactory">
				<beans:property name="brokerURL" value="tcp://localhost:61616"/>

		</beans:property>
	</beans:bean>

Hmmm that error doesn't look too good. Can you create a JIRA issue for this?

[Mark Fisher]

Before you post an issue on JIRA, can you describe what version you are using?

The first thing I noticed (also based on other questions you've been raising) is that the configuration is for RC1 (with the 'ws' namespace's 'outbound-gateway' element). However, that stack trace is clearly not RC1 (there is no DefaultMessageBus for example).

I was using M6 before and latter I tried to change the same code with RCI.May be would be the problem with jars m6 and RC1 together. After tht I created a fresh project and tried to run the same code with RCI jars alone and this ClassCastException disappeared but I have the below Exception (as taked b4)still when using jms outbound gateway

HTTP ERROR: 500

javax.jms.JMSException: Failed to build body from bytes. Reason: java.io.IOException: org.springframework.integration.message.GenericMessage
RequestURI=/admin/message.jsp

javax.el.ELException: javax.jms.JMSException: Failed to build body from bytes. Reason: java.io.IOException: org.springframework.integration.message.GenericMessage

I dont understand this exception cos I tried to check what class it returns and it gave me the below Class. Im using these two packages:

import org.springframework.integration.core.Message;
import org.springframework.integration.core.MessageChannel;

Message<String> message = MessageBuilder.withPayload(requestXml)
			.setHeader(AbstractWebServiceOutboundGateway.SOAP_ACTION_PROPERTY_KEY, "http://mycompany.com/hr/schemas").build();

System.out.println(message.getClass());

Returned Class:

class org.springframework.integration.message.GenericMessage

Well, in this case using two versions of the same library in the same project is definitely not a good idea ...

Yes I totally agree with u!
