> Per http://www.wso2.org/wiki/display/mashup/File+Host+Object there doesn't seem to be a way to determine whether a file exists before reading from it.  A read returns an empty string, and a length zero, but also causes the file to come into existence.  See the enclosed JavaScript, who's "retrieve" operation tries to determine whether a file exists or not prior to reading from it.
