File sharing not supported

“File sharing not supported” error message from JChat client connected to an Openfire server from a workstation outside the domain. The Openfire server is not integrated with the domain via LDAP. The error occurs only from external to internal. The same user is able to receive files from an internal domain JChat client. What could be the issue?

Hello! I am afraid that this is a question for the JChat developers.

Openfire provides several mechanisms for sharing files, including XEP-0363: Http File Upload, XEP-0050: SOCKS5 Bytestreams and XEP-0047: In-Band Bytestreams, and probably others that I can’t think of right now and/or do not require specific server support.

Some of these protocols require specific plugins to be installed, and/or some network configuration.

I am not sure which if any of these mechanisms are supported by JChat.
