我正在使用tomcat作为我的网络服务器。我有需要用户单击“编辑”按钮后需要重新启动tomcat服务器的应用程序。为此，我在控制器上编写了如下代码：

if (updateResult ==1) 
{
   //String command = "/home/sunil_shiwankar/Tempo/apache-tomcat-6.0.32/startup.sh";//for linux use .sh
    String command = this.getClass().getResource("/").getPath();
    System.out.println("{{{{{{{{{{{{{{{{{{{{{{{{{{{"+ command);
    command = command.replace(command.substring(command.lastIndexOf("webapps"), command.length()), "");
    System.out.println("{{{{{{{{{{{{{{{{{{{{{{{{{{{ AFTER MODIFYING COMMAND IS "+ command);
    try
    {
      String shutDownCommand = command+"bin/shutdown.sh";
      Process child = Runtime.getRuntime().exec(shutDownCommand);
      System.out.println("{{{{{{{{{{{{{{{{{{{{{{{{{{{ SHUTDOWN TOMCAT SUCCESSFULLY }}}}}}}}}}}}}}");
    } catch (Exception e) 
    {
        String inExceptionStartCommand = command+"bin/startup.sh";
        Process child = Runtime.getRuntime().exec(inExceptionStartCommand);
        System.out.println("{{{{{{{{{{{{{{{{{{{{{{{{{{{ TOMCAT STARTED WITH EXCEPTION SUCCESSFULLY }}}}}}}}}}}}}}");
        e.printStackTrace();
    }
        String normalStartCommand = command+"bin/startup.sh"; 
        Process child = Runtime.getRuntime().exec(normalStartCommand);
        System.out.println("{{{{{{{{{{{{{{{{{{{{{{{{{{{ TOMCAT STARTED WITOUT EXCEPTION SUCCESSFULLY }}}}}}}}}}}}}}");
}

我的tomcat版本6.0.32，在运行我的应用程序时，它会关闭tomcat服务器，并以异常开头
