552 transfer failed at

Hi:

We use FTPS (The Secure FTP factory version is 6.0.1) to send file and got error message

552 transfer failed at com.jscape.inet.ftps.FtpsClient.a(Unknown Source)
at com.jscape.inet.ftps.FtpsClient.readResponse(Unkno wn Source)

at com.jscape.inet.ftps.Ftps.upload(Unknown Source)

What does the error code 552 really mean?

Thanks,

Zheng
