I have no idea what i means, so i jsut tried the same as everyone which is:

downgrade to Java 6 same error
upgraede to Java 7 again, same error
triple Buffing disable ( Nvidia grafick card)
Firewall disabled
tried to clear the cache on Java via the control panel, but since i just re-installed it was pretty much empty

I dunno what else it can be

please help

I just downloaded the cient, and am having a java problem as well. Mine is something to do with the OpenGL, which i have updated and still get the same problem. Still trying to figure this one out.

@Djpwny: My guess is a network issue. Something isn't installed correctly or Java doesn't have access to the network. It could be something simple such as a security setting or it could be software installed incorrectly. If someone else doesn't come up with an answer before, I'll see if I can find something to help you. PM me or follow up if I don't post again.

@Tanto: If it has to do with OpenGL, you probably aren't having a similar problem. Post your error logs.

Hm I've wound never haved guessed that,
i tried installing it on my labtop, it had no problems there, so the port, and what other settings the Router might have seem to be okay

I dont know what else i can have on my computer which should cause a problem, firewall are disabled, and tried with no Anti viruses on
still the same

Check Java security settings. I'm not entirely sure which might interfere with Java attempting to bind to a socket. Is the computer that is having issues able to connect to other sites? Can you play other multiplayer Java games on it? Do you know what ports they use?

I've found a couple possible solutions and you may need to run some tests on you computer. The first (and easiest) possible solutions are the quesitons I asked above. If those are "yes", then it gets technical.

One possible problem is that another process is already using those ports. You can check it and see if anything is using ports TCP 1871 or UDP 1870. Run the program "netstat" from a command prompt and see if anything is one of these ports. If so, you may need to kill the process, uninstall the program, reconfigure it, etc. You can see what programs are using ports by running "netstat -b"

I could be completely off on this and it could be another issue. It's a start, though.

Got no problems connect to other sites,
and i can play Minecraft no problem

tried the "netstat -b" Cmd widow open its ran som connection, none of whitch were mentioning a Port number, only IP adresses
and it closed by it self before i got a chance to read the last Info it had written

[MagicManICT]

You need to open a command prompt first (Start>Run, cmd.exe) and then run netstat so that the output stays visible.

What you'll see is a list of active connections on your computer. The address is listed as <IP>:<port>. The IP can be either an IP address or a name (such as the computer your running on or an URL). Check the port numbers. If one of the ports are occupied already, Java won't be able to use it and will terminate.

Again, it could be something other than this. If anyone has any ideas, they're welcome to suggest it. This was the most common cause of this issue for Java, though.
