I have two webservices WS1 and WS2 Is there any way in Apache Camel to select which services to call based on certain conditions?
Yes there is, for example content-based router.
RouteBuilder builder = new RouteBuilder() {
public void configure() {
errorHandler(deadLetterChannel("mock:error"));
from("direct:a")
.choice()
.when(header("foo").isEqualTo("bar"))
.to("direct:b")
.when(header("foo").isEqualTo("cheese"))
.to("direct:c")
.otherwise()
.to("direct:d");
}
};

I am implementing a Code first cxf web service. How does cxf decide the soap:address part of generated wsdl ? Is it using the hostname from the deployed machine ?
Also, can I change the endpoint protocol from http to https programmatically or by-configuration on the deployed application ?
You can use Spring for this.
you must create an impl for the interface service.
#WebService(endpointInterface = "com.services.MyAwesomeService")
public class MyAwesomeServiceImpl implements MyAwesomeService {
#Override
public String sayHi(String text) {
return "Hello " + text;
}
}
And config vía Spring.
#Configuration
public class ServiceConfig {
#Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
return new SpringBus();
}
#Bean(name = "myAwesomeService")
public MyAwesomeServiceImpl myAwesomeService() {
return new MyAwesomeServiceImpl();
}
#Bean
public Endpoint endpoint() {
EndpointImpl endpoint = new EndpointImpl(springBus(), myAwesomeService());
endpoint.publish("/MyAwesomeService");
return endpoint;
}
}
After doing this. You will have your service published in the path /MyAwesomeService.
To configure the HTTPS protocol, I recommend you configure it in the application container (Tomcat) or dedicated front (Apache, F5, etc.)
I am new to JUnit. I am trying to write test case for camel route and processor. I don't know how to start. Here is my route
from("activemq:queue1").process("queueprocessor").toD("activemq:queue2").
I need help to mock my endpoints and processor.
Here mocked all endpoints using "isMockEndpoints" & added expected body content to endpoint(activemq:queue2) and by sending same content as input to mocked endpoint(activemq: queue1) verified assert is satisfied or not.
public class MockEndpointsJUnit4Test extends CamelTestSupport {
#Override
public String isMockEndpoints() {
// override this method and return the pattern for which endpoints to mock.
// use * to indicate all
return "*";
}
#Test
public void testMockAllEndpoints() throws Exception {
// notice we have automatic mocked all endpoints and the name of the endpoints is "mock:uri"
getMockEndpoint("mock:activemq:queue2").expectedMessageCount(1);
getMockEndpoint("mock:activemq:queue2").expectedBodiesReceived("Hello World");
template.sendBody("mock:activemq:queue1", "Hello World");
getMockEndpoint("mock:activemq:queue2").assertIsSatisfied();
/* additional test to ensure correct endpoints in registry */
/* all the endpoints was mocked */
assertNotNull(context.hasEndpoint("mock:activemq:queue1"));
assertNotNull(context.hasEndpoint("mock:activemq:queue2"));
}
}
I am working currently on project where Apache CXF is integrated with Apache Camel. Apache CXF is a solution that we use to expose a WebService then marshal/unmarshal SOAP request and pass it to Camel. This is pretty standard. By default a POJO dataFormat in ApacheCXF is used however there is a need for getting some information form SOAP headers "" and pass it to Camel. My question is how to do this? When I use Interceptor in Apache CXF I can get information that I need but I cannot pass it then to Camel. The class below is a CXF Interceptor
public class MyInterceptor extends AbstractSoapInterceptor {
//..... some variables
#Override
public void handleMessage(SoapMessage message) throws Fault {
//..some logic and then setting a variable
message.getExchange().put("Foo", "Bar");
}
}
... and class below is Camel Processor that is eventually called:
public class MyCamelProcessor implements Processor {
#Override
public void process(Exchange exchange) throws Exception {
//how can I read information from CXF Intercptor here?
//how can I read "Foo" value?
}
}
I understand that Exchange class that is used by Apache CXF is different then Exchange used by Camel however there should be a way of passing information between these two integrated technologies?
Finally, I solved it how follow:
In my context, I have a consumer service with camel-cxf component which is routed to Processor.
CxfEndpoint class from Camel has a method call setInInterceptors:
public void setInInterceptors(List<org.apache.cxf.interceptor.Interceptor<? extends org.apache.cxf.message.Message>> interceptors)
Therefore, if we define the next in our beans definitions file:
...
<cxf:cxfEndpoint id="consumerId"
address="/myservice"
serviceClass="com.example.service.MyServiceSEI">
<cxf:inInterceptors>
<ref bean="myInterceptor"/>
</cxf:inInterceptors>
</cxf:cxfEndpoint>
<bean id="myInterceptor" class="com.example.interceptors.MyInterceptor" />
Then, in our custom Interceptor we can set any variable in a map
...
import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.binding.soap.interceptor.AbstractSoapInterceptor;
...
public class MyInterceptor extends AbstractSoapInterceptor {
public MyInterceptor() {
super(Phase.RECEIVE);
}
#Override
public void handleMessage(SoapMessage message) throws Fault {
//..some logic and then setting a variable
message.getExchange().put("Foo", "Bar");
}
}
Finally, we can get the variables in our Processor, using org.apache.cxf.message.Message class, different from org.apache.camel.Message used with Exchange.getIn() method
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.cxf.message.Message;
import org.apache.camel.component.cxf.common.message.CxfConstants;
public class MyCamelProcessor implements Processor {
#Override
public void process(Exchange exchange) throws Exception {
//how can I read information from CXF Intercptor here?
//how can I read "Foo" value?
Message cxfMessage = exchange.getIn().getHeader(CxfConstants.CAMEL_CXF_MESSAGE, Message.class);
String foo = (String) cxfMessage.getExchange().get("Foo");
// read message from camel context
org.apache.camel.Message inMessage = exchange.getIn();
...
}
}

How to publish a web service class with #WebServiceProvider?What is the endpoint URL in this case?
Could we generate wsdl with #WebServiceProvider as in the case with
#WebService?What does the "wsdlLocation" attribute mean in #WebServiceProvider?
For instance
#ServiceMode(value = Service.Mode.MESSAGE)
#WebServiceProvider(portName = "ProviderPort",serviceName = "ProviderService",
targetNamespace = "http://bean/")
public class WebServiceProviderImpl implements Provider<SOAPMessage>
Simplest way is-
package server;
import javax.xml.ws.Endpoint;
public class Server {
protected Server() throws Exception {
System.out.println("Starting Server");
System.out.println("Starting SoapService1");
Object implementor = new WebServiceProviderImpl();
String address = "http://localhost:8123/SoapContext/SoapPort1";
Endpoint.publish(address, implementor);
}
public static void main(String args[]) throws Exception {
new Server();
System.out.println("Server ready...");
Thread.sleep(5 * 60 * 1000);
System.out.println("Server exiting");
System.exit(0);
}
The URL is "address". As far as I understand you can specify it as you like, as long as the port is free.
Alternatively, you could use JAXWsServerFactoryBean which is a part of CXF.
You would do the same thing as you would with an SEI.
And yes, it does generate a WSDL for you.
You can create your client stubs from it using wsimport just like an SEI
I am developing a Restful web service which allow user to set all parameters in POJO and send it to server side web service, then web service will store this data and return generated Id back to client. But my POJO has parent-child relationship that contain set of POJO, So how can I do this using RESTful web service. I also written a code to fetch data from server using web service and its working fine. But for this issue please help me.
Thanks.
I am not sure if I understood your question correctly. I guess some sample code will help. If you are using RestTemplate then serializing and deserializing will be done for you automatically. RestTemplate uses Jackson to parse JSON so you don't need to worry about parent/child relationship in your POJO.
So here is an example. There are 1000's of examples out there on internet. Thats how I learnt.
RestTemplate restclient = new RestTemplate();
Product product = restclient.getForObject(url,Product.class);
System.out.println(product.getCoupons().getName());
Where as product is (I completely made this up myself),
public class Product {
#JsonProperty("id")
private String id;
#JsonProperty("coupons")
private Coupons coupons;
#JsonProperty("id")
public String getId() {
return id;
}
#JsonProperty("id")
public void setId(String id) {
this.id = id;
}
#JsonProperty("coupons")
public Coupons getCoupons() {
return coupons;
}
#JsonProperty("coupons")
public void setCoupons(Coupons coupons) {
this.coupons = coupons;
}
}
public class Coupons {
#JsonProperty("name")
private String name;
#JsonProperty("name")
public String getName() {
return name;
}
#JsonProperty("name")
public void setName(String name) {
this.name = name;
}
}
Let me know if I misunderstood your question, I can update my answer accordingly.
