JavaSampler Result - jmeter

Question

Hi Iam Fresher in Jmeter
I have wrote one Java Sampler code. I don't know that is correct or wrong. If I put that URL and parameter in Http Request getting proper result, but if written as a javasampler i didn't get that result, Iam getting Pass result but no response and request data
My Sampler code is:
package org.apache.jmeter.protocol.java.test;
import java.io.PrintWriter;
import java.io.Serializable;
import java.io.StringWriter;
import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;
public class ExampleJavaSampler extends AbstractJavaSamplerClient implements Serializable {
String mySvc = "";
JavaSamplerContext context;
public Arguments getDefaultParameters(){
Arguments arg = new Arguments();
arg.addArgument("url", "http://www.url.com:5252/Switch/Download");
arg.addArgument("e_type", "bank");
arg.addArgument("e_id", "4");
arg.addArgument("b_id", "1");
arg.addArgument("a_id", "0002");
arg.addArgument("link_branch", "");
arg.addArgument("terminal_id", "");
arg.addArgument("version", "10");
arg.addArgument("entity", "100");
System.out.println("inside default");
return arg;
}
public void setupTest(JavaSamplerContext context) {
System.out.println("inside Setup");
}
public SampleResult runTest(JavaSamplerContext context) {
System.out.println("Inside Run test:");
String urls = context.getParameter("url");
String e_type = context.getParameter("e_type");
String e_id = context.getParameter("e_id");
String b_id = context.getParameter("b_id");
String a_id = context.getParameter("a_id");
String l_branch = context.getParameter("e_type");
String t_id = context.getParameter("e_type");
String oion = context.getParameter("e_type");
String entity = context.getParameter("e");
SampleResult result = new SampleResult();
result.getURL();
result.setSampleLabel("Test Result");
result.setDataType(SampleResult.TEXT);
result.sampleStart();
try{
java.net.URL url = new java.net.URL(urls+"?=e_type="+e_type+"&e_id="+e_id+"&b_id="+b_id);
System.out.println(url);
java.net.HttpURLConnection connection = (java.net.HttpURLConnection)url.openConnection(); // have to cast connection
connection.setRequestMethod("POST");
connection.connect();
result.sampleEnd(); // stop stopwatch
result.setSuccessful( true );
result.setResponseMessage( "Successfully performed action" );
result.setResponseCodeOK(); // 200 code
} catch (Exception e) {
result.sampleEnd(); // stop stopwatch
result.setSuccessful( false );
result.setResponseMessage( "Exception: " + e );
// get stack trace as a String to return as document data
java.io.StringWriter stringWriter = new java.io.StringWriter();
e.printStackTrace( new java.io.PrintWriter( stringWriter ) );
result.setResponseData( stringWriter.toString() );
result.setDataType( org.apache.jmeter.samplers.SampleResult.TEXT );
result.setResponseCode( "500" );
}
return result;
}
void teardownTest() {
System.out.println("inside tear Down:");
}
}
After this code I made .jar file and put lib/ext. Then I called in Javarequest and all parameters are diplayed there, then I run this Test plan, getting success message nut no result
This is the right way or we have to add some thing for there for result?

I've already responded here.
You need to call result.setResponseData() inside your try block elsewise you won't see anything on success. "Response Data" piece of "View Results Tree" listener is populated only on error according to your code.
