502 Active FTP not allowed in Netbean while synchornizing to remote Server

I am trying to synchronize my local project in remote server. It created the base directory also, but can't upload files. The Error message is 502 Active FTP not allowed. I am using netbean IDE. What should be the problem??

Thank yo开发者_如何学JAVAu in Advance!

I believe a 502 Active FTP Not Allowed is a message coming from your FTP server. I believe it is telling you that it only allows FTP connections in passive mode.

In Manage Remote Connections for the connection you are using, check the box Passive Mode and try again.
