Java中MS-Exchange获取任务

从Exchange服务器检索任务列表时遇到问题。我已经有了添加和更新任务的代码，但是我无法继续进行检索。下面是它的代码：

public void getEvents(String a_sPrefix, String a_sMailboxName,
        String a_sFolderName) throws ExchangeException, IOException {

    WebdavResource wrFolder = getExchangeWebdavResource(a_sPrefix,
            a_sMailboxName, a_sFolderName);

    // Get the session:
    HttpClient httpClient = wrFolder.retrieveSessionInstance();

    String sPrefix = "";

    if (a_sPrefix != null && a_sPrefix.length() > 0) {
        sPrefix = a_sPrefix + "/";
    }

    // Build the Url of the contacts folder:
    String sFolderUrl = m_sExchangeUrl + sPrefix + a_sMailboxName + "/"
            + a_sFolderName;

    // Escape any spaces:
    sFolderUrl = sFolderUrl.replaceAll("\\s", "%20");

    // Try to find the event first:
    String sQuery = "<?xml version=\"1.0\"?>"
            + "<D:searchrequest xmlns:D = \"DAV:\" xmlns:e = \"http://schemas.microsoft.com/exchange/\">"
            + "<D:sql>" + "SELECT "/*\"DAV:uid\"*/ + "FROM \"" + sFolderUrl + "\" " +
            // "WHERE \"e:extensionattribute1\" = '"+a_exEvent.getId()+"'" +
            "</D:sql>" + "</D:searchrequest>";
    System.out.println("The Query:" + sQuery);

    SearchMethod searchMethod = new SearchMethod(sFolderUrl, sQuery);

    int iStatusCode = httpClient.executeMethod(searchMethod);

    // See if there was an error:
    handleReturnCode(iStatusCode);

    Enumeration resp = searchMethod.getResponses();
    byte[] b = searchMethod.getResponseBody();

    Enumeration<String> enumMatchingUrls = searchMethod.getAllResponseURLs();
    while (enumMatchingUrls != null && enumMatchingUrls.hasMoreElements()) {
        String sEventUrl = (String) enumMatchingUrls.nextElement();
        Enumeration ob = searchMethod.getResponseProperties(sEventUrl);
        while (ob.hasMoreElements()) {
            BaseProperty v = (BaseProperty) ob.nextElement();
            log(v.toString());
        }

    }

    /*
     * if (enumMatchingUrls != null && enumMatchingUrls.hasMoreElements()) {
     * sEventUrl = (String)enumMatchingUrls.nextElement(); bExists = true; }
     * else { // This is a new contact: sEventUrl = sFolderUrl + "/" +
     * a_exEvent.getUniqueIdForUrl() + ".EML"; bExists = false; }
     */
}

我正在连接一个虚拟机，如果这有什么用的话。如果你想要更多的信息，不要犹豫

编辑：一个小小的误解。我正在尝试从exchange日历中获取事件/任务。有什么帮助吗？
