Hi Armine, have you already took a look into chapter 28 of the tutorial? Regarding to the Too many open files behaviour some documents a referred. On some window configurations it has been observed that the underlying selector of a Dispatcher accepts only a small number of concurrent connections. This is a JRE/OS behaviour. As a workaround you can set the number of the dispatchers with a higher value -> org.xsocket.connection.dispatcher.initialCount. Or you can set org.xsocket.connection.dispatcher.maxHandles. I also added a new JUnit-Test based on your test (see http://xsocket.svn.sourceforge.net/viewvc/xsocket/xsocket/core/trunk/src/test/java/org/xsocket/connection/ManyConcurrentServerTest.java?view=markup). Within the continuous integration xSocket's tests runs on a Windows XP professional/SP3 as well as on a RedHed (centos) multicore platform.

Hi Amine, xSocket give you 3 options to send data. By default the write operation will be synchronous, that means the write call returns after the data is written (into the OS-internal SO_SNDBUF). If you set the FlushMode to async, the write method will return immediately. The write operation(s) will be done in the background. xSocket uses an internal second-level buffer to do this. If you have written a large amount of data and you closes the connection, xSocket tries to flush all the data of the second-level buffer before the connection will be closed physically. If you want to avoid large second-level write buffer or to have more control over the flowcontrol, you can use xSocket's IWriteCompletionHandler support. Please see chapter 25 of the tutorial.

Hi Kirk, by calling the server's getOpenConnections() you will get all the server-side connections. Please note, that this method is not defined by the IServer interface. For an example see http://xsocket.svn.sourceforge.net/viewvc/xsocket/xsocket/core/trunk/src/test/java/org/xsocket/connection/NotifyAllClientsTest.java?view=markup Gregor 2009/1/18 Kirk Chang <ki...@pc...> > Hi, > > How do I send a String("Hello all") to all clients connected ? > > I am using INonBlockingConnection to connect to clients. > > > Thanks, > Kirk > > > ------------------------------------------------------------------------------ > This SF.net email is sponsored by: > SourcForge Community > SourceForge wants to tell your story. > http://p.sf.net/sfu/sf-spreadtheword > _______________________________________________ > xSocket-develop mailing list > xSo...@li... > https://lists.sourceforge.net/lists/listinfo/xsocket-develop > > |

I forgot to state that I am using Windows XP with 4GB of ram and Q6600
Quad Core processor.

Hello,
I wanted to see how many sockets I could have listening in my program and it
seems that 42 is the limit. Once it tries to create socket 43, it throws an
IOException: "too many open files". I was hoping for at least a couple
hundred.
Here is some sample code:
Random random = new Random();
> for(int i = 0;i<1000;i++) {
> System.out.println(i + " | Creating server..");
> try {
> IServer server = new Server(random.nextInt(40000) + 1024,
> new DummyHandler());
>
server.start();
> } catch (UnknownHostException e) {
> e.printStackTrace();
> } catch (IOException e) {
> e.printStackTrace();
> }
> System.out.println(i + " | Created server!");
> }
Here is the output:

I am not sure why it would reach this limit so early, or how to solve it. I
think using a single Selector for all sockets would be a start. Is this
possible with the current design of xSocket? Perhaps there is a way to
handle large amount of sockets that I am not aware of. I would like to
continue using xSocket for my project, and any help is appreciated.
Thank you,
Amine

Hi,
How do I send a String("Hello all") to all clients connected ?

Hi Amine, if you close the connection, all data of the write queue will be flushed automatically. This is especially true for flushMode Async. If you write data in (default) flushMode Sync, the write method returns only if the data ids written.

Hi Serguei, unfortunately no workaround exists. The next version of xSocket (which will be released in 1 or 2 weeks) will support additional constructors.

Hi, In some cases in multi-homed environment it is often required to specify client IP address and port. It looks like this binding is not supported in current version of xsocket. Does a simple work-around exists? What are chances that appropriate constructors will be added in the future? -- Regards, Serguei Belikov |

Hi Jens, data will be segmented on the network level. If the onData() method is called, it is not predictable how many bytes will be received. This causes that each NonBlockingConnection read method will throw a BufferUnderflowException, if not enough data is available An example for reading mutlipart records can be found in the tutorial chapter 13 -16: http://xsocket.sourceforge.net/core/tutorial/V2/TutorialCore.htm Gregor 2008/12/12 Jens Ramhorst <jen...@ju...> > Hello, > I have a big problem. > I am new to xSocket and my written Server close every connection after > two packets without reason. > The packagesize is equal. > Example: > The first 2 bytes of data are the length of all data, that the client > send.

Hello,
I have a big problem.
I am new to xSocket and my written Server close every connection after
two packets without reason.
The packagesize is equal.
Example:
The first 2 bytes of data are the length of all data, that the client
send. In this example 1492 bytes. With the nbc.readByte-Method i try to
read all 1492 bytes. But after 2 packages (for e.g. 500 bytes) the Sever
close the connection and System.out.println is never reached.
I looked with wireshark and after the first packege the server send ACK,
after the second the server send ACK and FIN,ACK.
The Code:
public boolean onData(INonBlockingConnection nbc) throws IOException,
BufferUnderflowException, ClosedChannelException,
MaxReadSizeExceededException {
byte[] lengthArray = new byte[2];
for (int i=0; i<2; i++) {
lengthArray[i] =
ByteKit.fromUnsignedInt(nbc.readByte()); // Reads the complete length of
data the client send
}
int length =
ByteKit.chartoInt((byte)0,(byte)0,lengthArray[0],lengthArray[1]); // The
length of data
byte dataArray[] = new byte[length];
dataArray = nbc.readBytesByLength(length); // Read all data
in array
System.out.println("Done"!); // Never reached
}
Has anybody an idea.
Best regards.
Jens

Hi sly, as a static typed language java requires that the type of a variable is defined at declaration time. This variable can only be set with the data of the declared type.

Hi, Is it possible to use string from a string variable as a name for new created nbc? What method should I use? String name = "nbc"; name = new NonBlockingConnection(...) // name should be "nbc" regards, sly ---------------------------------------------------- Skąd pochodzi Twoje nazwisko?

hi,<br>
<br>
My java application with xsocket server communicate with Flash client.<br>
Method onData works. But how to trigger onConnect method? It should be<br>
triggered when my Flash client connects, right? Do I have to send<br>
additional manually some kind of greetings message in order to trigger<br>
onConnnnect method?<br>
