Getting a TomCat exception when trying to browse remotehost

Getting a TomCat exception when trying to browse remotehost

I am trying to import Squid log files via FTP (I am using ProFTPd on Fedora Core 5).

When I try to browse for the access.log file, I am getting a TomCat error in the popup browser window where I assume I am supposed to be seeing a list of files to select from.

I am attaching the support log files.

I have verified that both PASV and non-PASV ftp work correctly and get me to the correct location on the FC5 server and can obtain the file list.

Any insight would be greatly appreciated.

Thank you.
