post soap request using apache-common-httpclient

post soap with httpclient.java

private void postSOAPXML(String soapBody)
{
	try {
	// Get target URL
	HttpClient httpclient = new DefaultHttpClient();

	StringEntity strEntity = new StringEntity(soapBody, "text/xml", "UTF-8");
	HttpPost post = new HttpPost(CAI3G_URL);
	post.setHeader("SOAPAction","CAI3G#Create");
	post.setEntity(strEntity);
	        
	// Execute request
        HttpResponse response = httpclient.execute(post);
        HttpEntity respEntity = response.getEntity();
            
            if (respEntity != null) {
            	logger.info("Response:");
            	logger.info(EntityUtils.toString(respEntity));
            } else {
            	logger.error("No Response");
            }
	}
	catch (Exception e) {
			logger.error("Other exception = " + e.toString());
	} 
}

Is it operation name or url is required in post.setHeader("SOAPAction","CAI3G#Create");
I mean SOAPAction value is URL or operation name

operation name, should be able to find in your schema file.
