Question

首先：我对Apache Camel和Stack Overflow都很陌生！

我创建了一条路由，用于过滤和下载SFTP服务器上的文件，并在处理后删除这些文件。

我的问题：在我的本地计算机上，路线运行良好。当我在生产服务器上部署此路由（相同的.war）时，下载有效，但当FTP组件尝试删除该文件时，我得到以下异常。开发和生产机器具有相同的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）

任何想法???

这是路线：

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

Answer 1

这是另一类问题。您需要详细了解生产环境。您是否为Camel应用程序使用了一些特殊的应用程序服务器，或者如何运行它？

该错误表示某种类加载问题。

Answer 2

此问题仍未解决。在Windows Server中运行Tomcat（即使是管理员），我们也无法使这条路由工作。在Ubuntu Linux中的Tomcat中部署路由它从一开始就没有任何修改！
