Java Language:-

-----------------------------

package com.web;

import java.net.Authenticator;

import java.net.HttpURLConnection;

import java.net.PasswordAuthentication;

import java.net.URL;

public class TestMain {

  public static void main(String[] args) throws Exception {

  Authenticator.setDefault(new Authenticator() {

  // This method is called when a password-protected URL is accessed

  @Override

  protected PasswordAuthentication getPasswordAuthentication() {

  return new PasswordAuthentication("UserId", "Password".toCharArray());

  }

  });

  HttpURLConnection con = (HttpURLConnection) new URL("http://Server:50200/ChannelAdminService/ChannelAdmin").openConnection();

  con.setRequestMethod("POST");

  con.setRequestProperty("content-type", "text/xml");

  con.setDoOutput(true);

  String s = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:com:sap:netweaver:pi:monitoring\">" +

  "   <soapenv:Header/>" +

  "   <soapenv:Body>" +

  "      <urn:getChannelAutomationStatus>" +

  "         <!--Zero or more repetitions:-->" +

  "         <channels name=\"CC_File_Sender\" service=\"BC_Test\" party=\"\">" +

  "         </channels>" +

  "      </urn:getChannelAutomationStatus>" +

  "   </soapenv:Body>" +

  "</soapenv:Envelope>";

  con.getOutputStream().write(s.getBytes());

  byte[] b = new byte[con.getInputStream().available()];

  con.getInputStream().read(b);

  System.out.println(new String(b));

  }

}

Java Language (using WSDL):-

-----------------------------

package com.web;

import java.net.MalformedURLException;

import java.util.ArrayList;

import java.util.List;

import javax.xml.ws.BindingProvider;

import com.sap.netweaver.pi.monitoring.ChannelAdminDescriptor;

public class MyMain {

  public static void main(String[] args) throws MalformedURLException, GetChannelAutomationStatusFault {

  IChannelAdmin ica = new ChannelAdminService().getChannelAdminPort();

  BindingProvider bp = (BindingProvider) ica;

  List<ChannelAdminStatus> status = c.getStatus();

  System.out.println(status.get(0).getActivationState());

  }

  }

}

Go Language:-

-----------------------------

package main

import (

  "bytes"

  "fmt"

  "io/ioutil"

  "net/http"

)

func main() {

  in := `<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:com:sap:netweaver:pi:monitoring">

         <!--Zero or more repetitions:-->

         <channels name="CC_File_Sender" service="BC_Test" party="">

       

         </channels>

      </urn:getChannelAutomationStatus>

   </soapenv:Body>

</soapenv:Envelope>`

  req, _ := http.NewRequest("POST", "http://Server:50200/ChannelAdminService/ChannelAdmin", bytes.NewBufferString(in))

  req.SetBasicAuth("UserId", "Password")

  req.Header.Set("content-type", "text/xml")

  client := http.Client{}

  res, _ := client.Do(req)

  resB, _ := ioutil.ReadAll(res.Body)

  fmt.Println(string(resB))
