This is a full working example    import org apache http HttpEntity  import org apache http HttpResponse  import org apache http client HttpClient  import org apache http client methods HttpPost   import org apache http entity StringEntity  import org apache http impl client DefaultHttpClient  import org apache http util EntityUtils   public void callWebService String soapAction  String soapEnvBody   throws IOException          Create a StringEntity for the SOAP XML      String body    lt  xml version   1 0   encoding   UTF-8    gt  lt SOAP-ENV Envelope xmlns SOAP-ENV   http   schemas xmlsoap org soap envelope    xmlns ns1   http   example com v1 0 Records   xmlns xsd   http   www w3 org 2001 XMLSchema   xmlns xsi   http   www w3 org 2001 XMLSchema-instance   xmlns SOAP-ENC   http   schemas xmlsoap org soap encoding    SOAP-ENV encodingStyle   http   schemas xmlsoap org soap encoding    gt  lt SOAP-ENV Body gt   soapEnvBody   lt  SOAP-ENV Body gt  lt  SOAP-ENV Envelope gt        StringEntity stringEntity   new StringEntity body   UTF-8        stringEntity setChunked true           Request parameters and other properties      HttpPost httpPost   new HttpPost  http   example com soapservice        httpPost setEntity stringEntity       httpPost addHeader  Accept    text xml        httpPost addHeader  SOAPAction   soapAction           Execute and get the response      HttpClient httpClient   new DefaultHttpClient        HttpResponse response   httpClient execute httpPost       HttpEntity entity   response getEntity         String strResponse   null      if  entity    null            strResponse   EntityUtils toString entity

The simplest way to identify what needs to be set on the soap action when invoking WCF service through a java client would to load the wsdl  go to the operation name matching the service  From there pick up the action URI and set it in the soap action header  You are done   eg  from wsdl   lt wsdl operation name  MyOperation  gt     lt wsdl input wsaw Action  http   tempuri org IMyService MyOperation  message  tns IMyService MyOperation InputMessage    gt     lt wsdl output wsaw Action  http   tempuri org IMyService MyServiceResponse  message  tns IMyService MyOperation OutputMessage    gt      Now in the java code we should set the soap action as the Action URI     The rest of the httpPost object properties have not been shown for brevity string actionURI  http   tempuri org IMyService MyOperation   httpPost setHeader   SOAPAction   actionURI

using org apache http api         You need to include SOAPAction as a header in the request  As you have httpPost and requestWrapper handles  there are three ways adding the header      1  httpPost addHeader   SOAPAction   strReferenceToSoapActionValue     2  httpPost setHeader   SOAPAction   strReferenceToSoapActionValue     3  requestWrapper setHeader   SOAPAction   strReferenceToSoapActionValue      Only difference is that addHeader allows multiple values with same header name and setHeader allows unique header names only  setHeader     over writes first header with the same name     You can go with any of these on your requirement

The soapAction must passed as a http-header parameter - when used  it s not part of the http-body payload   Look here for an example with apache httpclient  http   svn apache org repos asf httpcomponents oac hc3x trunk src examples PostSOAP java
