我正在使用 commons-codec-1.3 jar linkin-j signpost-core-1.2.1.1 中的 jar

对于 LinkedIn API。它在 Windows 服务器上运行良好。我在 ubuntu 中有相同的代码，但我得到了错误

oAuthService=LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(key, secret);
        request=oAuthService.getOAuthRequestToken("http://www.google.com");

我在 getOAuthRequestToken 上遇到错误

我终于弄清楚了这个问题。它发生date and time在我的 ubuntu 服务器中。在 ubuntu 中，当我更改为当前日期和时间时，它显示昨天的日期。它工作正常。
