哪位高手在java中调用过sharepoint中的webservice啊

谁在java中调用过sharepoint中的webservice啊？
看微软的文档，调用webservice时用到了好多微软自定义的一些类库，比如他的网络身份凭证：credentials，真不知道在java中怎么使用。有过这方面经验的人吗，指导一下，谢谢。


[解决办法]
如果只是调用sharepoint本身的websevice，可以参考
http://java-sharepoint-library.googlecode.com/svn/trunk

我的webservice都是自己写的，方便使用，借你参考下，用的axis2

Java code

        private SPServicesStub m_SPStub;    private ServiceClient m_ServiceClient;    private Options m_Options;    /**     * Generates auth     *     * @param wsdlUrl     *            WSDL URL     * @param username     * @param pwd     * @param hostname     * @param domaname     * @throws Exception     */    public void generateAuth(String wsdlUrl, String username, String pwd, String hostname, String domaname) throws Exception    {        if (wsdlUrl == null || wsdlUrl.equals(""))        {            m_SPStub = new SPServicesStub();        }        else        {            m_SPStub = new SPServicesStub(wsdlUrl);        }        m_WSDL=wsdlUrl;        m_ServiceClient = m_SPStub._getServiceClient();        m_ServiceClient.engageModule("addressing");        Options options = m_ServiceClient.getOptions();        options.setTimeOutInMilliSeconds(2 * 60 * 1000);        options.setUseSeparateListener(false);        HttpTransportProperties.Authenticator basicauth = new HttpTransportProperties.Authenticator();        basicauth.setUsername(username);        basicauth.setPassword(pwd);        basicauth.setHost(hostname);        basicauth.setDomain(domaname);        List authPrefs = new ArrayList(1);        authPrefs.add(AuthPolicy.NTLM);        basicauth.setAuthSchemes(authPrefs);        options.setProperty(HTTPConstants.AUTHENTICATE, basicauth);        m_ServiceClient.setOptions(options);        m_Options=options;        // _serviceClient.getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED,Boolean.FALSE);    }
