import sun.net.ftp.FtpClient - Error under Java 1.3 and below

[Gurkha Bahadur]

Hello,
I am implementing FTP using import sun.net.ftp.FtpClient.
It works peachy fine under J2SDK1.4.0 but throws the following error under JDK1.3
sun.net.ftp.FtpProtocolException: STOR filename
PLEASE HELP!
Thanks

Hmmm. sun.* classes are not part of the public Java API and can break from one version to the next. If you require full ftp client functionality not supplied by the core Java API, then try this LGPL client library, the NetComponents multi-protocol libary or Jakarta Commons Net.

hi Gurkha
can u do printStackTrace() and provide us the complete error?
u can also decompile the sun.net.ftp.FtpClient code to see whats there in STOR instruction execution (which is actually a put command in ftp)...
its weired because it doesn't do whole lot in put() method of FtpClient that issues ftp command STOR with a filename...
regards
