Axis java client error "Unrecognized SSL message, plaintext connection"

Hi:
I try to ask a webservice to an https server through a proxy server using a simple webservice client in java (Axis), and get the error of "Unrecognized SSL message, plaintext connection". The client code does have Https.proxy properties setting.

Note that I am able to use web browser client to send the https requests via the proxy server. In the browser setting, the https proxy server port is sepcified as "443", and same setting to Https.proxyPort on the client code . Since the web browser client made a succesful request through the proxy server, I assumed "443" is the correct port number used in both proxy server port and the https server, correct?


I have stucked on the issue for a whole week. Am I miss anything?
Thanks in advance !!!

Below is the client code snippet:

String KEYSTORE_LOCATION = "c:/dir1/jre/lib/securityacerts";
System.setProperty("javax.net.ssl.trustStore", KEYSTORE_LOCATION);
System.getProperties().put("proxySet", "true");
System.getProperties().put("https.proxyHost", "proxyserver");
System.getProperties().put("https.proxyPort", "443");
String xmlRequest =ClmUtils.readLocalFile("C:/testdata/request");

Service service = new Service();
Call call = (Call) service.createCall();
call.setUsername("username") ;
call.setPassword("password") ;
options.setDefaultURL(WSDL_LOCATION);// the wsdl_location points to a https url

call.setTargetEndpointAddress( new URL(options.getURL()) );
SOAPBodyElement[] soapElementArr = new SOAPBodyElement[1];

org.w3c.dom.Document document = getXmlDocument(xmlRequest) ;
org.w3c.dom.Element eax = (document.getDocumentElement()) ;
soapElementArr[0] = new SOAPBodyElement(eax) ;
Vector outputVector = (Vector)call.invoke(soapElementArr);
SOAPBodyElement soapElement = (SOAPBodyElement) outputVector.get(0);
Element element = soapElement.getAsDOM();
String responseXml = XMLUtils.ElementToString(element);
