Send a SOAP request to a remote web service and get a response using apache Camel

问题

I'm doing a development to send a SOAP request to a remote web service and get a response using apache Camel.

In this case, I succesfully generated Client Side wsdl2java Code using the cxf-codegen-plugin for the WSDl mentioned below.

• Sample WSDL URL : http://www.webservicex.net/stockquote.asmx?WSDL

And after doing some researches, I created below sample code to send a SOAP request to the web service defined in there and get a response with apache Camel using the generated client code.

CamelContext context = new DefaultCamelContext();

HttpComponent httpComponent = new HttpComponent();
context.addComponent("http", httpComponent);

ProducerTemplate template = context.createProducerTemplate();

GetQuote getQuote = new GetQuote();
getQuote.setSymbol("test123");

GetQuoteResponse getQuoteResponse = template.requestBody("http://www.webservicex.net/stockquote.asmx",getQuote, GetQuoteResponse.class);

System.out.println(getQuoteResponse);

But it gives below error.

Caused by: org.apache.camel.InvalidPayloadException: No body available of type: java.io.InputStream but has value: net.webservicex.GetQuote@10bdf5e5 of type: net.webservicex.GetQuote on: Message[ID-namal-PC-33172-1469806939935-0-1].

What have I miss here? Data binding? or anything else? I generated the client code using cxf so how I can send this using cxf?

What I simply want is to send a SOAP request to a remote web service and get a response using apache Camel.

• Camel Version : 2.9.0
• Java Version : 1.7.x / 1.8.x

It would be better to use the CXF component for this. Depending on how the CXF code is generated you might just send & receive a string instead of an object in your example - see How to tell cxf to keep the wrapper types in methods? for more information.

Here's your example with CXF.

CamelContext context = new DefaultCamelContext();

CxfComponent cxfComponent = new CxfComponent(context);
CxfEndpoint serviceEndpoint =
    new CxfEndpoint("http://www.webservicex.net/stockquote.asmx", cxfComponent);

// Service class generated by CXF codegen plugin.
serviceEndpoint.setServiceClass(StockQuoteSoap.class);

ProducerTemplate template = context.createProducerTemplate();

// Request and response can be 'bare' or 'wrapped', see the service class.
String getQuoteResponse = template.requestBody(serviceEndpoint, "MSFT", String.class);

System.out.println(getQuoteResponse);
