problem with camel-http routing with spring dsl
Hi I am trying to call a webservice using camel-http component.
When I write my routing logic using java-dsl, it just works fine and I can
retrieve the soap response in String format as out message body. However,
when I do the same using spring-dsl I get the following error.
*WARN DirectProducer - No consumers available on endpoint:
Endpoint[direct://MyProducerUri] to process: Exchange[Message:
<soapenv:Envelope ....> .... </soapenv:Envelope>]*
and I get the response as null.
Following is my code and camel-route.xml.
*ApplicationContext applicationContext = new
ClassPathXmlApplicationContext("META-INF/spring/camel-route.xml");
CamelContext context = new SpringCamelContext(applicationContext);
try {
context.start();
String soapMessage = "<soapenv:Envelope ....>.....</soapenv:Envelope>"; //
Truncating the actual soap request xml content here with .... .
Exchange exchange = new DefaultExchange(context);
ProducerTemplate template = exchange.getContext().createProducerTemplate();
exchange.getIn().setBody(soapMessage);
exchange.setPattern(ExchangePattern.InOut);
exchange.getIn().setHeader("SOAPAction", "");
exchange = template.send("direct:MyProducerUri", exchange);
String output = exchange.getOut().getBody(String.class);
System.out.println(output);
} finally {
context.stop();
}*
camel-route.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:camel="http://camel.apache.org/schema/spring"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd">
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="direct:MyProducerUri"/>
<to
uri="http://localhost:8080/camel-example-cxf-tomcat/webservices/incident"/>
</route>
</camelContext>
</beans>
Routing logic in java dsl-->
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:MyProducerUri").to("http://localhost:8080/camel-example-cxf-tomcat/webservices/incident");
}
});
I have deployed the webservice in my local machine tomcat.
Please help me with this. I am sure this is some configuration issue.

This is wrong ^^^^, you should not create a new camel context. But
lookup the existing context from the spring application context
instead. As when spring startup, eg you need to call start on
applicationContext, then all the namespace gets executed, and there is
the Camel namespace parser which executes the <camelContext ...>
..</camelContext> from the XML file, and creates a new CamelContext
and enlist that into the spring app context bean registry.
Therefore you should lookup that bean.
eg
CamelContext context = applicationContext.getBean("myCamel, CamelContext.class);
And then in the XML file set the <camelContext id="myCamel" ...> eg
set the id attribute to give it an id, you can lookup.
