Java IRC channels?

I doubt this, as I've searched google many times looking for one with no luck. Are there any irc channels for java programmers where one can ask quick questions, or just talk about java in general? Something for quick answers to simple questions? Google searches only come up with millions of different java based irc clients, and how to create them.

send a message to the nickserv for help on registering your IRC nick.
/msg NickServ help register
/msg NickServ help identify
Once you've registered your nick, you'll be able to access the ##java chatroom

DPS 11.1.1.5.0 java.nio.channels.ClosedChannelException

Hi,
I've upgraded today to 11.1.1.5.0 all my DS and DPS from 11.1.1.3.0 on Redhat 5.6 x64, Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
I get this on my proxy after a while:
[29/Aug/2011:17:08:08 +0300] - BACKEND - WARN - Attempt to bind as to backend server ldap.example.com:389/ on connection server-example:124 failed. java.nio.channels.ClosedChannelException
[29/Aug/2011:17:08:08 +0300] - BACKEND - WARN - Attempt to bind as to backend server ldap.example.com:389/ on connection server-example:124 failed. java.nio.channels.ClosedChannelException
On the LDAP server I get
[29/Aug/2011:17:22:49 +0300] conn=91 op=766568 msgId=1 - SRCH base="" scope=0 filter="(objectClass=*)" attrs="1.1"
[29/Aug/2011:17:22:49 +0300] conn=91 op=766568 msgId=1 - RESULT err=0 tag=101 nentries=1 etime=0
which is DOSing my log file.
If I restart the proxy server the problem is gone for a while but it gets back after an hour or so thus making my whole LDAP infrastructure unusable.
regards,
Giannis

I disabled proactive monitor for failed server and the problem didn't occur for 15 hours. Then I got the following.
Just for the record, ldap.example.com is running on the same machine as DPS.

Java.nio.channels.ClosedChannelException using https

Hello,

Can anybody help me?

Jens,
Can you turn up your debug level to FINEST? It appears that during the read operation an attempt to access a channel closed to read occurs.
// Create binding -- set binding properties before you open the factory.
OracleDBBinding odbBinding = new OracleDBBinding();
// Create address.

// Open factory

// Get channel and open it.

Java.nio.channels.IllegalBlockingModeException

Hi,
Thanx for the reply. I am using Selecotor for read and if it timesout I used PrintWriter to write to Socket ( Not socket channel). So, once it comes out of select loop, it'd excecute PrintWriter.println("Timeout message....") statement. And at this statement I/m getting exception.

Java.nio.channels.Pipe?

Someone explain what java.nio.channels.Pipe should be uses for, and how to use it?

You can use this class to transfer the content of a channel from one thread to another thread.
The writing thread blocks when the pipe is full.

PipeReader pr = new PipeReader( p );
Thread t = new Thread( pr );
t.start();
fc.transferTo(0, fc.size(), p.sink() );
catch( IOException ioe )
ioe.printStackTrace();

you argument are very valid and i can't not invalid it , but how you say the here are crap in internet ( a lot of then ) but the years i have in internet one of the tool that give me more community sense is IRC , is a real-time interaction between ppl that want just share ( anything ) and even there are way to moderate the channels so that kind of problem that you can see in irc exist too in sdn forum and in both place can be somehow controlled so i don't see this a problem
the quality of the info need to confirm by the requester, you need have some common sense of doing things the sdn forum try to solve this with the P_O_IN_TS system that i think is quite broken system because ppl just answer the anything to expect hit the pot and get P_O_IN_TS .
i not the founder of the irc channel but of what i talk to the ppl there they want not just make a channel they want build a better community of sap user thing that from my point of view SDN is fail of do this.
my 2 cents.

Troubles with timeout using java.nio.channels and non-blocking sockets

Hello.
I have a server application that employs java.nio.channels with non-blocking sockets.
The server waits for connections. The client should connect and be first in sending data.
Timeouts are significant! If client exceeds the allowed time to send data, the server should break the connection.
The huge trouble I've discovered that I cannot control the timeout when client connects but remains silent.
My code looks as follows:
<pre>
Selector oSel;
SocketChannel oSockChan;
Socket oSock;
SelectionKey oSelKey;
Iterator<SelectionKey> oItSelKeys;
int iCurrState, iMask, iCount;
iCurrState = INT_SERVER_WORKING;
iMask = SelectionKey.OP_ACCEPT | SelectionKey.OP_CONNECT | SelectionKey.OP_READ | SelectionKey.OP_WRITE;
while ( iCurrState == INT_SERVER_WORKING )
try
*// retrieving next action*
iCount = oSel.select();
if ( iCount > 0 )
oItSelKeys = oSel.selectedKeys().iterator();
while ( oItSelKeys.hasNext() )
oSelKey = oItSelKeys.next();
oItSelKeys.remove();
if ( oSelKey.isValid() )
switch ( oSelKey.readyOps() & iMask ) {
case SelectionKey.OP_ACCEPT :
oSockChan = oSSockChan.accept();
oSockChan.configureBlocking(false);
oSock = oSockChan.socket();
oSock.setKeepAlive(true);
oSockChan.register(oSel,SelectionKey.OP_READ,new MyPacket(oSock.getInetAddress(),oSock.getPort()));
break;
case SelectionKey.OP_READ :
oSelKey.interestOps(0);
((MyPacket) oSelKey.attachment()).inRequest(); *// preparing request*
this.getReader().add(oSelKey); *// sending key to reading thread*
break;
case SelectionKey.OP_WRITE :
oSelKey.interestOps(0);
((MyRequest) oSelKey.attachment()).inResponse(); *// preparing response*
this.getWriter().add(oSelKey); *// sending key to writing thread*
break;
case SelectionKey.OP_CONNECT :
default :
*// nothing to do*
catch ( IOException oExcept )
*// do some actions*
</pre>
Timeouts are easily controlled by reading and writing threads (see OP_READ and OP_WRITE ).
But when a client just connects without consequent data send, the state of this connection remains as OP_ACCEPT. The connection remains open for arbitrarily large time and I cannot control it!
Please help with idea how can I terminate such connections!

How can I process the keys that weren't selected at the bottom of the loop? Should I use the method keys() ?Yes. Form a new set from keys() and removeAll(selectedKeys()). Do that before you process selectedKeys().
And the second moment: as I understood a single key may contain several operations simultaneously? Thus I should use several if's (but not if/else 'cause it's the equivalent of switch ... case ).If there is anything unclear about 'your switch statement is invalid. You need an if/else chain' I fail to see what it is. Try reading it again. And if several ifs were really the equivalent of "switch ... case", there wouldn't be a problem in the first place. They're not, and there is.

Yesterday Colloquy crashed on my iPad after an Arabic text string was pasted into the IRC channel that I was on. Another user using Linkinus was also affected. As I understand it, this vulnerability has to do with Webkit. What is being done about it?

Yesterday Colloquy crashed on my iPad after an Arabic text string was pasted into the IRC channel that I was on. Another user using Linkinus under Mountain Lion on her Macbook Pro was also affected. As I understand it, this vulnerability has to do with applications that use Webkit. What is being done about it? Can we expect security updates for Mountain Lion and iOS 6 soon?

AFAIK, there has not been an update regarding this issue as yet.

Java IRC bot.

hi, recently I started making an irc bot in Java. I was testing it out on my friend's server and everything seemed to be working, it was reading from the server, and was responding to the one command. I wanted to show it to my other friend so I changed the variables to match his irc server, and the bot couldn't connect. I was wondering if the problem was in my friend's server or in my code. (I'll include what the server sends when I connect at the bottom)

Okay yea, can anyoen tell me if the problem is in my code or the server? And if the problem is in the code could you please tell me what to change or point me in the right directin? thanks.

And yea, I realize it says that, but the steps to register are you enter the nick and the user which both come before that, so I was wondering if anyone with knowledge of how irc works could tell me if there's some other way of registering, or if the problem's in my code.Some IRC servers requires that an admin in the channel creates the user account.
KajOkay, glad to know it was supposed to say program :).
I'm pretty sure that it's not because the admin has to set up the acc. because this server was set up with the sole purpose of showing my friend my bot. However, it might be just that the server is retarded. I'm gonna try it on some other servers and see how it works there.

I believe what you want is a thread that waits for x seconds before doing something (ie say something). If after x seconds the thread hasnt been killed/reset then do something and reset the thread.
Your listen method should reset the thread everytime its called.
when I say reset the thread I mean the thread will be doing a wait() and when it wakes up it should check a flag to see whether or not the room is still quiet. Your listen() method should set this flag.
Thats a broad outline any hoo.

Detect loss of socket connection using java.nio.channels.Selector

I'm using the nio package to write a "proxy" type application, so I have a ServerSocketChannel listening for incoming connections from a client and then create a SocketChannel to connect to a server. Both SocketChannels are registered to the same Selector for OP_READ requests.
All works fine, until either the client or server drops the connection. How can I detect this has happened, so my proxy app can drop the other end of the connection ?
The Selector.select() method is not triggered by this event. I have tried using Selector.select(timeout) and then checking the status of each channel, but they still show isConnected()=true.
Thanks,
Phil Blake

[SOLVED] Arch Linux IRC Channel :: how do i register with NickServ?

I tried following the instrauctions in the wiki but nothing happens.
I've connected (/connect irc.freenode.net) and joined the channel (/join archlinux) but then when i type a message it says i am unable to send a message to the channel.
I proceed to try the two commands in the wiki but nothing appears to happen:
/msg nickserv help register
/msg nickserv help identify
What do I need to do exactly?

Nickserv should have sent instructions, like so:
4:58pm -- | -nickserv- help register
4:58pm -- | NickServ (NickServ@services.): ***** NickServ Help *****
4:58pm -- | NickServ (NickServ@services.): Help for REGISTER:
4:58pm -- | NickServ (NickServ@services.):
4:58pm -- | NickServ (NickServ@services.): This will register your current nickname with NickServ.
4:58pm -- | NickServ (NickServ@services.): This will allow you to assert some form of identity on
4:58pm -- | NickServ (NickServ@services.): the network and to be added to access lists. Furthermore,
4:58pm -- | NickServ (NickServ@services.): NickServ will warn users using your nick without
4:58pm -- | NickServ (NickServ@services.): identifying and allow you to kill ghosts.
4:58pm -- | NickServ (NickServ@services.): The password is a case-sensitive password that you make
4:58pm -- | NickServ (NickServ@services.): up. Please write down or memorize your password! You
4:58pm -- | NickServ (NickServ@services.): will need it later to change settings.
4:58pm -- | NickServ (NickServ@services.):
4:58pm -- | NickServ (NickServ@services.): You have to confirm the email address. To do this,
4:58pm -- | NickServ (NickServ@services.): follow the instructions in the message sent to the email
4:58pm -- | NickServ (NickServ@services.): address.
4:58pm -- | NickServ (NickServ@services.):
4:58pm -- | NickServ (NickServ@services.): Syntax: REGISTER <password> <email-address>
4:58pm -- | NickServ (NickServ@services.):
4:58pm -- | NickServ (NickServ@services.): Examples:
4:58pm -- | NickServ (NickServ@services.): /msg NickServ REGISTER bar [email protected]
4:58pm -- | NickServ (NickServ@services.): ***** End of Help *****
The responses from Nickserv won't show up in the #archlinux channel. They'll be in another buffer or tab in your IRC client.

Is java.nio.channels.FileLock thread safe ?

Hello,
I want to lock a file in exclusive mode. The 1.4.2 doc says the followings:
File locks are held on behalf of the entire Java virtual machine. They are not suitable for controlling access to a file by multiple threads within the same virtual machine.
File-lock objects are safe for use by multiple concurrent threads.
I'm confused. If They are not suitable for controlling access to a file by multiple threads within the same virtual machine, How can they be safe for use by multiple concurrent threads ?
thanks in advance...

I think it means that you still need to synchronize your threads around the code that obtains the lock and writes data to the file.
