Error Sending: java.net.ConnectException: Connection timed out

[MILINTICA]

I try to access an FTP site. A Java client runs through the web page so you can drop files. Whenever I have the following error message: Error Sending: java.net.ConnectException: Connection timed out: connect. The window allows me to select a file to file does not open. I work for a company and thus via a LAN. I looked and conducted tests on the proxy and the firewall without success. I tested on my personal DSL line and it works. Can anyone know what's the problem ?

If it is a corporate network there are always security around. To see if security does not block access to this site JAVA. Otherwise have you tried with a FTP software like FileZilla. ?

"Connection timed out" sounds like a network issue and nothing to do with J2SE. To prove it try "telnet <host> 80" and see if it times out the same way. firewall on the way that simply eats the packets without telling the sender things like "No Route to host".

Specified in java.security to indicate the caching policy for un-successful name lookups from the name service.. The value is specified as as integer to indicate the number of seconds to cache the failure for un-successful lookups. A value of 0 indicates "never cache". A value of -1 indicates "cache forever".
