Getting NullPointerException when talking to NMR Endpoint
Hi,
I checked the example given in servicemix 4.0 CXF-Camel NMR.
I tried to follow the example.
I created a CXF Stack webservice and deployed it as an OSGI Bundle in the
servicemix.
I used the nmr endpoint instead of hosting it on http port.
My spring config file is as follows
I had another bundle which has following route inside it.
from("direct:NMR")
.to("nmr:Persons");
I sent a soap envelope message on the Direct EndPoint.
The problem here is that the message is not reaching to the NMR Endpoint.
It is giving following exception.
java.lang.NullPointerException
at
org.apache.servicemix.camel.nmr.ServiceMixProducer.process(ServiceMixProducer.java:44)
at
org.apache.camel.processor.SendProcessor$1.doInProducer(SendProcessor.java:97)
at
org.apache.camel.processor.SendProcessor$1.doInProducer(SendProcessor.java:95)
The surprising thing here is that the example provided with the servicemix
4.0 CXF-Camel NMR is working fine. The only change I observed is that the
example is keeping all the things in the same bundle whereas in my case the
NMR endpoint and the router are in different bundles.
Please help.
With Regards
Harbeer Kadian

Re: Getting NullPointerException when talking to NMR Endpoint
HI,
The CXF Bundle is deployed properly.
I had these lines in the log files.
Creating Service {http://impl.ws.esb.com/}PersonEndPointImplImplService from
class com.esb.ws.impl.PersonEndPointImpl
ServerImpl | g.apache.cxf.endpoint.ServerImpl 91 |
Setting the server's publish address to be nmr:Persons
Also I did not received any exception when starting the CXF Bundle.

Re: Getting NullPointerException when talking to NMR Endpoint
Hi,
I am using following version of servicemix
FUSE ESB v. 4.2.0
Also I am giving more description of what I did.
I have a cxf webservice exposed as nmr endpoint using following
configuration.
jaxws:endpoint id="PersonEndPointWebService"
implementor="#PersonEndPoint"
address="nmr:Persons"/>
And my another bundle contains a route
from("direct:Initiator")
.to("nmr:Persons");
Also I went through following content given on this webpage.
It tells that you have to use a certain format while defining any nmr
endpoint on a weservice annotated class.
nmr:endpoint:serviceNamespace[sep]serviceName[sep]endpointName
Do I also need to add all this information in my spring beans file.

NoSuchEndpointException: getting exception when talking to http endpoint using camel
Hi,
I created a new camel router to send a message to a webservice using
camel-http component.
The configure method of the router is as follows.
public void configure() throws Exception {
from("direct:ProducerUri")
.to("http://localhost:8083/ConnectPlatform?supportedEndPointsRequest=DataManager";);
}
The wsdl for the webservice is located at following url
http://localhost:8083/ConnectPlatform?wsdl
The servicemix gave exception when i tried to add this router to the camel
context.
org.apache.camel.NoSuchEndpointException: No endpoint could be found for:
http://localhost:8083/ConnectPlatform?supportedEndPointsRequest=DataManager,
please check your classpath contains the needed camel component jar.

I also added the following packages in the OSGI Import-Package header
org.apache.camel.component.http
org.apache.camel.component.http.helper
Still i am getting the same exception.
Also when i perform command osgi/list on servicemix
I found that the camel-http component is not in the Started stage.

Re: NoSuchEndpointException: getting exception when talking to http endpoint using camel
I created the camel context in following way
JndiContext jndiContext = new JndiContext();
CamelContext camelContext = new DefaultCamelContext(jndiContext);
I have used jndiContext because i have to bind some bean components.
Ex:
jndiContext.bind("endPoint", new EndPointImpl());
One more question for you.
Do you know any book or any good website which comprehensively explains how
to work with apache camel.

Re: NoSuchEndpointException: getting exception when talking to http endpoint using camel
Hi,
Thanks for your reply.
But my problem in not regarding CamelContextFactory.
When I am using a http endpoint to communicate with a web service, the
servicemix is failing to find the correct jar in the classpath to create a
http endpoint.
Please tell what are the prerequisites for using a http endpoint.
With Regards

Re: NoSuchEndpointException: getting exception when talking to http endpoint using camel
Hi,
I checked the respective jar(camel-osgi) in cache folder.
To my surprise, the CompositeRegistry class is not present there.
Is it like I am using old version of camel-osgi feature.

Re: NoSuchEndpointException: getting exception when talking to http endpoint using camel
Hi,
I did as per your suggestion.
Here is the piece of code
private CamelContext camelContext;
private CamelContextFactory camelContextFactory;
camelContextFactory = new CamelContextFactory();
camelContext = camelContextFactory.createContext();
((DefaultCamelContext)camelContext).setRegistry(new
JndiRegistry(jndiContext));
but still i am getting the same exception.
Constructor threw exception; nested exception is
org.apache.camel.NoSuchEndpointException:
No endpoint could be found for:
http://localhost:8095/HelloWebService/services/Hello,
please check your classpath contains the needed camel component jar.
at
org.springframework.beans.factory.support.ConstructorResolver.autowir
eConstructor(ConstructorResolver.java:254)
I am once again giving a detail description of my problem.
My route is as follows
from("direct:ProducerUri")
.to("http://localhost:8095/HelloWebService/services/Hello";);
I am creating the required soap message as follows
String soapMessage = "http://schemas.xmlsoap.org/soap/envelope/\";>http://cxf.ws.studies.xh.org/\";>http://cxf.ws.studies.xh.org/\";>"
+ "Harbeer Kadian" +
"";
// Camel will convert string to Document object for me
exchange.getIn().setBody(soapMessage, Document.class);
exchange.setPattern(ExchangePattern.InOut);
exchange = producerTemplate.send("direct:ProducerUri", exchange);
I am using an OSGI bundle to deploy this code in servicemix.
Other than this I am not providing any information particular to http
endpoint in my code or any of the configuration file
bundle-context.xml
bundle-context-osgi.xml
Looks like all the problems are happening because of the OSGI bundle.
Please tell if you have any idea about this problem.
With Regards

Re: NoSuchEndpointException: getting exception when talking to http endpoint using camel
Hi,
I have got the solution for problem.
We have to add a component of type http in camelContext. Then only the
camelContext is able to
understand a http uri.
camelContext.addComponent("http", new HttpComponent());
The String name can be any valid string.
I dont know, whether it is osgi which is forcing us to add explicitly
HttpComponent to talk to a http endpoint, or this is the camel way of
sending messages to endpoints.
Thanks for the valuable suggestions added to understand the problem.
With Regads

Not able to invoke webservice using http component
Hi,
I deployed a simple webservice on TomCat Server.
I created following route to access the webservice using apache camel.
from("direct:ProducerUri")
.to("http://localhost:8095/WebServiceTutorial/services/Hello?username=admin&password=admin";);
I created the exchange in the following way
String soapMessage = "http://schemas.xmlsoap.org/soap/envelope/\";
xmlns:tut=\"http://tutorial.com\";>"
+ "Harbeer Kadian" +
"";
XmlConverter xmlConverter = new XmlConverter();
Document input = xmlConverter.toDOMDocument(soapMessage);
exchange.getIn().setBody(input);
exchange.setPattern(ExchangePattern.InOut);
//added this line after seeing no soapAction found error on Tom Cat Server
log
exchange.getIn().setHeader("SOAPAction", "");
exchange = producerTemplate.send("direct:ProducerUri", exchange);
Document output = (Document)exchange.getOut().getBody();
System.out.println(output);
I am getting null as output.
Also on the tom cat server log, no exception is coming.
I have no idea how to invoke webservice using http component.
Please help me.
With Regards
Harbeer Kadian

Re: Not able to invoke webservice using http component
Hi,
thanks for the reply.
I did not changed the input soap message into Document and directly sent it.
I got the soap message reply in the form of String.
The reply is as follows
http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>http://tutorial.com";>Hello Harbeer
Kadian
Now i want to read this output and change it into java objects, just like
what a webservice client do.
Do there are any standard api to do this.
Or I have to use some sort of XQuery or XSLT Transformer to get the soap
body.
With Regards

How to change java application into Enterprise Integration Pattern
Hi,
I have a class, which contains a java object(say message which I need to
transmit).
This class is present in an OSGI Bundle named connector.
This OSGI Bundle also contains classes need to validate this message.
There is another OSGI Bundle which contains a transformer class which can
convert this java object message into XML Message using Apache velocity.
The XML Message need to be converted into a Soap message, but the
information required to convert it
into soap message is present in the bundle named connector.
Now the control is inside connector bundle, and I have that java object
message ready.
If i have to do the operations mentioned above in a java application, i may
have done it as follows
Pseudo code:
1) call a validation method and send the java object as a parameter.
2) If the validation passes, call the transform method of the Transformer
class, and get the xml as reply.
3) Get the required information to build soapmessage and convert it into
soap message.
sendJavaObject(Object message) {
validate(message);
String xmlMessage = Transformer.transform(message);
String soapMessage = appendSoapInfo(xmlMessage);
}
But the thing here is that all the controlling of method calling is
happening from the Connector bundle.
If I see an Camel Integration pattern they will tell some thing like this
Object Message ->>>>> Validator >>>>> Transformer >>>>
soapAppender --->>>> callWebservice.
and then the response will be sent using the out property present in the
MessageExchange.
But my implementation looks like this
Object Message ->>>>>> Validator
Object Message -->>>>>> Transformer
String Message --->>>>> SoapAppender
String soapMessage >>>>> Call Web Service using camel Http Component
->>>> String soapResponse
I am also adding a diagram giving pictorial representation of our
application. http://old.nabble.com/file/p28179266/ExecuteOperation.png
ExecuteOperation.png
Please give me some guidelines regarding how to change a java application
into Enterprise Integration Patterns.
With Regards
Harbeer Kadian
