首先：我对 Apache Camel 和 Stack Overflow 还是很陌生！

我创建了一个路由，该路由从 SFTP 服务器过滤和下载文件，并在处理后删除这些文件。

我的问题：在我的本地计算机上，该路线完美运行。当我在生产服务器上部署此路由（相同的 .war）时，下载有效，但是当 FTP 组件尝试删除文件时，我得到以下异常。开发和生产机器有相同的camel、tomcat和java版本。唯一的区别是操作系统（开发：Windows 7，产品：Windows Server 2008 R2）

有任何想法吗？？？

这是路线：

        String uri = "sftp://" + sftpUserId + "@" + sftpHost + "?" +
                "password=" + sftpPassword + "&" +
                "recursive=true" + "&" +                
                "filter=#fileFilter" + "&" +  
                "binary=true" + "&" +
                "delete=true";

这是其他类型的问题。您需要更多地了解生产环境。您是否为您的 Camel 应用程序使用了一些特殊的应用程序服务器，或者您如何运行它？

该错误表明某种类加载问题。

这个问题仍然没有解决。在 Windows Server 中的 Tomcat 中运行（即使以管理员身份），我们也没有设法使这条路线工作。在 Ubuntu Linux 中的 Tomcat 中部署路由，它从一开始就可以正常工作，无需任何修改！！！
