Are you saying that you want to send the java.io.File object in the message so that the receiver can read the file? If so, that is not possible. Nor is it possible to send a java.io.Stream/Writer/whatever. These objects, besides probably not being serializable, do not contain the file contents anyway. And I assume that you are interested in getting the file contents to the receiver. In which case the only option is to read the file contents and send those in the message. Another option - if both the sender and receiver has visibility to the file, you could just send the full path name. This would work, for instance, in a Windows environment if you used a UNC name (example: \\myhost\sharename\path\to\the\file.txt).
