我们有2个cisco手机:一个用于呼叫管理员,另一个用于他的主管.

当经理回答并将主管的电话置于静音状态时,我们需要创建一个会议.我们正在尝试使用JTApi实现它:等待事件TermConnActiveEv,然后尝试创建会议.

这是代码示例.

if (callEv instanceof TermConnActiveEv) {
CiscoCall thisCall = (CiscoCall) callEv.getCall();
TerminalConnection connection = ((TermConnActiveEv) callEv).getTerminalConnection();

if (thisCall.getState() != Call.ACTIVE)
{
    System.out.println("call is not active");
    return;
}
try {
    CiscoCall newCall = (CiscoCall) provider.createCall();
    newCall.consult(connection);
    newCall.conference(thisCall);

    ....

然而,PreConditionException被抛出.我们做错了什么？

我正在使用EWS Java API 1.1.5 ,我试图将服务绑定到收件箱文件夹,如下所示:

ExchangeService service = new ExchangeService();
        ExchangeCredentials credentials = new WebCredentials(email, password);
        service.setCredentials(credentials);
        service.setUrl(new java.net.URI("https://" + host
                + "/EWS/Exchange.asmx"));
Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox);

我从jsp页面调用上面的代码.

但我得到NullPointerException:
