我正在开发一个以 XML 形式来回调用的 Web 服务程序。然而，我的问题不在于此。当我在我的机器上本地(在 Eclipse 中)运行它时，它似乎可以工作。但是，当我的同事运行它时/如果我尝试在服务器上运行它，他甚至在调用 Web 服务之前就得到了这个异常:

ClientMain.java java.lang.IllegalArgumentException 中的异常#6:2012-07-09T08:19:44-0400

有谁知道为什么它会在一台机器上而不是另一台机器上进行争论？构建应该不是问题，因为我将整个 eclipse 工作区复制到拇指驱动器上(因此所有相关的 jar 和构建路径都应该保留下来)。就服务器运行而言，我将整个程序导出为可运行的 jar(运行 Eclipse Indigo)并遇到了类似的问题。

如有任何见解，我将不胜感激!

运行类型检查:

    public static void runTypeCheck(String sRunType)
        {
            try
            {
             //Hard-coded in "yesterday" as the date
             sRunType = "DT";

             System.out.println("******************************************************");
             DateTimeFormatter parser2 = ISODateTimeFormat.dateTimeNoMillis();

             if (sRunType.equals("DT")) 
             {
                 System.out.println("Running by Yesterday's Date ...");
                 Calendar cal = Calendar.getInstance();
                 cal.add(Calendar.DATE, -1);
                 DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
                 sRunType =  dateFormat.format(cal.getTime());
                 System.out.println(sRunType);
                 sRunType = sRunType.replaceAll("-0500", "-05:00");
                 sRunType = "DT" + sRunType;
                 requestRun(sRunType);
             }
System.out.println("******************************************************");

       }
       catch(Exception e)
       {
           System.out.println("Exception #4 in ClientMain.java " + e);
           try
           {
              postMail("Exception #4 in ClientMain.java " + e);
           }
           catch (Exception e1)
           {
              e1.printStackTrace();
           }
           System.exit(16);
        }  
    }

只输出:

最佳答案

问题是您从 strRunType.substring(2,strRunType.length()) 获得的“日期”不是日期的有效 lexicalRepresentation .

您需要正确设置输入值的格式才能解析为 XMLGregorianCalendar 对象。

错误是您在日期的 -04:00 中缺少 :。

由于 sRunType = sRunType.replaceAll("-0500", "-05:00"); 代码，您一定已经知道了...除了您使用的是 5 而不是一个 4？
