Apache Camel FTP Download does not delete remote file

First of all: I am quite new to Apache Camel and to Stack Overflow!

I have created a route which filters and downloads files from an SFTP Server and deletes those after processing.

My problem: On my local computer the route works perfectly. When I deploy this route (the same .war) on the production server, the download works but when the FTP component tries to delete the file I get the exception below. The development and production machine have the same camel, tomcat and java version. The only difference is the OS (Dev: Windows 7, Prod: Windows Server 2008 R2)

Any ideas???

Here's the route:

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

This problem is still unsolved. Running in Tomcat in a Windows Server (even as administrator) we did not manage to make this route work. Deploying the route in a Tomcat in Ubuntu Linux it worked right from the start without any modifications!!!

This is some other kind of problem. You need to tell more about the production environment. Do you use some special application server for your Camel app or how do you run it?

That error indicates some kind of class loading issue.
