Apache Camel SOAP/CXF request to Server (Spring Boot) - spring-boot

Question

I am trying to make requests to dedicated WSDL server with the help of Apache Camel CXF.
I have the WSDL URL:
http://www.learnwebservices.com/services/tempconverter?wsdl
I've made the Java classes of WSDL using the cxf-codegen-plugin:
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<version>3.4.2</version>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<goals>
<goal>wsdl2java</goal>
</goals>
<configuration>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/tempconverter.wsdl</wsdl>
<packagenames>
<packagename>office.planet.integrations.merlion</packagename>
</packagenames>
</wsdlOption>
</wsdlOptions>
</configuration>
</execution>
</executions>
</plugin>
I have the following Camel route:
#Component
public class MerlionRoute
extends RouteBuilder {
#Override
public void configure() throws Exception {
from("direct:celsius-to-fahrenheit")
.process(exchange -> {
System.out.println("HELLO!!!!!");
CelsiusToFahrenheitRequest c = new CelsiusToFahrenheitRequest();
c.setTemperatureInCelsius(Double.valueOf(exchange.getIn().getHeader("num").toString()));
exchange.getIn().setBody(c);
})
.setHeader(CxfConstants.OPERATION_NAME, constant("CelsiusToFahrenheit"))
.setHeader(CxfConstants.OPERATION_NAMESPACE, constant("{{endpoint.namespace}}"))
.to("cxf:bean:cxfConvertTemp")
.process(exchange -> {
System.out.println("WE ARE HERE");
MessageContentsList response = (MessageContentsList) exchange.getIn().getBody();
CelsiusToFahrenheitResponse r = (CelsiusToFahrenheitResponse) response.get(0);
exchange.getIn().setBody("Temp in Farenheit: "+r.getTemperatureInFahrenheit());
System.out.println(r.getTemperatureInFahrenheit());
})
.end();
}
}
The Bean class of the EndPoint:
#Configuration
public class CxfBeans {
#Value("${endpoint.wsdl}")
private String SOAP_URL;
#Bean(name = "cxfConvertTemp")
public CxfEndpoint buildCxfEndpoint() {
CxfEndpoint cxf = new CxfEndpoint();
cxf.setAddress(SOAP_URL);
cxf.setServiceClass(TempConverterEndpoint.class);
cxf.setWsdlURL(SOAP_URL);
return cxf;
}
}
And the WSDL endpoint:
endpoint.wsdl=http://www.learnwebservices.com/services/tempconverter?wsdl
endpoint.namespace=http://learnwebservices.com/services/tempconverter
When I am launching the project, my route starts, but nothing happens.
Only this I can see:
2022-03-31 18:41:44.933 INFO 44313 --- [ restartedMain] o.a.c.w.s.f.ReflectionServiceFactoryBean : Creating Service {http://learnwebservices.com/services/tempconverter}TempConverterEndpointService from WSDL: http://www.learnwebservices.com/services/tempconverter?wsdl
How shall I request the data from WSDL server within the Camel CXF? What am I doing wrong?

Answer 1

Your route needs to be triggered. As it stands, nothing calls your from endpoint "direct:celsius-to-fahrenheit", and thus indeed, nothing happens.
Assuming you want this route to be triggered only once, you could define your from endpoint as "timer://celsius-to-fahrenheit?repeatCount=1".
See Camel Timer component.
