我最近一直在与zookeeper合作,以满足分布式应用程序的可靠性要求.我正在使用三台计算机,我遵循了本教程:
http://sanjivblogs.blogspot.ie/2011/04/deploying-zookeeper-ensemble.html
我一步一步地确保我做得很好,但是现在当我用动物园开始我的动物园管理员时
./zkServer.sh start
我正在为所有计算机获取这些例外:

但是我不知道我做错了什么.我的目标是在不同的机器中同步我的动物园管理员,以获得始终可用的服务.我去了zookeeper.apache.orgWebPäge并查找有关如何配置和启动zookeeper的相同信息,但是我采用的步骤与之前相同.
如果有人可以帮助我,那我真的很乐意.提前致谢.
我已经在这里看到了许多与此异常相关的问题,并且大多数问题都是通过"commons-file-upload"从apache 添加jar来解决的.我试图使用这个解决方案,我已经为我的所有项目添加了相同版本的jar,但它似乎没有解决问题,我仍然面临着问题.我知道这个问题已被提出,但我想知道是否有人可以帮我解决这个具体问题.这是我的堆栈跟踪:

当我调用的方法抛出异常getParts,从我的课RestServer用HttpServletRequest的,我一直在寻找信息和它说,使用的jar的版本必须为所有项目一样,我做了这样的说法,但没有工作.
这段代码调用getParts():
private Map<String,Object> getParameters(HttpServletRequest request,boolean jsonp, String callback) {
Map<String,Object> lsParameteres = new HashMap<String, Object>();
Collection<Part> parts = null;
try {
parts = request.getParts();//The exception begins here!
如果有人能帮助我,我将不胜感激,谢谢你的时间.最好的祝福.
我正在尝试连接到通过 HTTPS 的第三方 URL。他们告诉我们，我们只需要向他们发送 HTTPS POST（不需要证书/密钥库）。但是，我收到以下异常：
