JMeter testing SOAP web service programmatically - jmeter

Question

Using JMeter APIs, I tried to call a SOAP web service programmatically.
After executing the service, when I checked the web service server logs, no transaction / entry is made over there. It seems the SOAP request did not send to the server at all. But, when I tried to invoke the web service directly using SOAPConnection call() method, with out JMeter APIs, it is working fine and server could generate logs.
Could any one please check it out and correct me on sending SOAP requests using JMeter APIs?
My full source code is as follows:
JMeterUtils.setJMeterHome("JmeterHome");
JMeterUtils.loadJMeterProperties("JmeterHome\\bin\\jmeter.properties");
JMeterUtils.initLogging();
JMeterUtils.initLocale();
HashTree testPlanTree=new HashTree();
HTTPSampler httpSampler=new HTTPSampler();
httpSampler.setDomain("domain");
httpSampler.setPort(<port number>);
httpSampler.setProtocol("http");
httpSampler.setPath("/wsdl");
httpSampler.setMethod("GET");
httpSampler.setName("Webservice Sampler");
httpSampler.setPostBodyRaw(true);
HeaderManager headerManager=new HeaderManager();
headerManager.add(new Header("SM_USER", "xyz#abc.com"));
headerManager.add(new Header("Content-Type","text/xml; charset=utf-8"));
headerManager.add(new Header("SOAPAction","http://example.com:<port number>/services/MyWebService?wsdl"));
httpSampler.setHeaderManager(headerManager);
HTTPArgument httpArgument=new HTTPArgument();
httpArgument.setValue(<SOAP Message>);
httpSampler.addTestElement(httpArgument);
LoopController loopController=new LoopController();
loopController.setLoops(1);
loopController.addTestElement(httpSampler);
loopController.setFirst(true);
loopController.initialize();
ThreadGroup threadGroup=new ThreadGroup();
threadGroup.setNumThreads(5);
threadGroup.setRampUp(1);
threadGroup.setSamplerController(loopController);
TestPlan testPlan=new TestPlan("Web Service Operations Test Plan");
testPlanTree.add("testPlan", testPlan);
testPlanTree.add("threadGroup",threadGroup);
testPlanTree.add("httpSampler",httpSampler);
testPlanTree.add("loopController",loopController);
SaveService.saveTree(testPlanTree, new FileOutputStream("jmeter_api.jmx"));
Summariser summary=null;
String summariserName=JMeterUtils.getPropDefault("summariser.name", "summary");
if (summariserName.length() > 0) {
summary = new Summariser(summariserName);
}
String reportFile = "report.jtl";
ResultCollector logger = new ResultCollector(summary);
logger.setFilename(reportFile);
testPlanTree.add(testPlanTree.getArray()[0], logger);
jmeter.configure(testPlanTree);
jmeter.run();
System.exit(0);
I am getting the following output in the Jmeter log file:

You are going not recommended way of creating a JMeter test, check out Building a WebService Test Plan to learn how to do it using JMeter GUI.
If for some reason you need to create a SOAP request programmatically, you can get a known good test plan hashtree structure by calling SaveService.loadTree() method passing an existing .jmx script as a parameter so you will have a reference test plan in your debugger which you can re-create using JMeter API.
You can find an example of adding a Header Manager to the HTTP Request here
In any case I would strongly recommend to double check that the script is doing what it is supposed to be doing via View Results Tree listener or with a sniffer tool like Wireshark
