connection lost or...?

Question

I got strange problems with one ftp-server.
I use edtftpj in my application to upload some files.
The problem:
Very often, I don't know when exactly, it seems that there is no connection any more or so.
im passive mode the log is printing -->pasv continuesly
in active mode it's printing -->port "strange ip's starting with 0.0.x.x" continuesly

I mailed the administrator of the server, as this problem does not occur on a different server and also not on my local ftp-server
but he can't help me.
The strange thing is that it occurs sometimes (often) but not always.
Is anything known about that? Maby any special setup required or so?

Thanks for your help

Answer 3

Now I don't underdstand anything anymoe....
In the Test Program (with connect , dir and then quit)
the error is "unexpected null reply received"
can this be catched?

But I really don't understand, because in the main application there is also
only one class which deals with ftpj and the code for ftp is that, that I posted.
Maybe it's a swing internal thing thing, which I don't understand,
the class is a subclass of JInternalFrame with a progressBar inside
in the constructor i do some setup and add the progreesbar and then call connect()
the code of connect() is the one I posted.....this maybe the error: calling connect from the constrcuctor

Ok, as I planned to change the gui from "DesktopFrame-sytle" to another ,an setting the progressbar to a fix location somewhere and not in an InternlaFrame which is build just before connecting to ftp, maybe the error is away, I will tell you when I've done so.

I guess for the "null reply" you have a solution, where to catch it the best

Thanks for your help

Answer 4

Make sure you have version 1.5.2, the latest one.

Answer 5

I have 1.5.2

i guess i can catch it with

catch(Exception e)
{
//couldn't connect//
}
