Null response when sending a SOAP request to Zimbra server

[fgb]

Hello,

I am trying to send a SOAP request to Zimbra server in order to authenticate and perform admin tasks.

I am sure I am missing a point somewhere but can't find where.

Here is the SOAP request I am sending:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<context xmlns="urn:zimbra">
<nonotify/>
<noqualify/>
</context>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<AuthRequest xmlns="urn:zimbraAccount">
<name>admin@64bitad.int</name>
<password>password</password>
</AuthRequest>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Here is the java code:

SOAPConnectionFactory sfc = SOAPConnectionFactory.newInstance();
		SOAPConnection connection = sfc.createConnection();
    	
    	MessageFactory mf = MessageFactory.newInstance();
        SOAPMessage sm = mf.createMessage();
        SOAPHeader sh = sm.getSOAPHeader();
        SOAPBody sb = sm.getSOAPBody();
        
        /* Build soap header */
        QName headerName = new QName("urn:zimbra", "context");
        SOAPHeaderElement headerElement = sh.addHeaderElement(headerName);
        QName noNotifyQName = new QName("nonotify");
        headerElement.addChildElement(noNotifyQName);
        
        QName noQualifyQName = new QName("noqualify");
        headerElement.addChildElement(noQualifyQName);

        /* Build soap body */
        QName serviceName = new QName("urn:zimbraAdmin", "AuthRequest");
        SOAPBodyElement bodyElement = sb.addBodyElement(serviceName);
        QName nameQn = new QName("name");
        SOAPElement nameElementValue = bodyElement.addChildElement(nameQn);
        nameElementValue.addTextNode("admin@64bitad.int");
        QName passwordQn = new QName("password");
        SOAPElement passwordElementValue = bodyElement.addChildElement(passwordQn);
        passwordElementValue.addTextNode("password");

        sm.writeTo(System.out);

        URL url = new URL("https://fgb-desktop:7071/service/admin/soap");
        
        SOAPMessage response = connection.call(sm, url);
        System.out.println(response.getContentDescription());
        return sm;

Thanks
