Address already in use: JVM_Bind

Hello,
I have a application client-server, the socket client connects to the server. After awhile, the server pushes news connections back. In the part client appears:
java.net.ConnectException: Connection refused: connect
I detect the problem and try to reconnect the server, it gives: Address already in use: JVM_Bind
Can I avoid the first one?
Have I to close the clients before the server reconnects?
Thank you.
Regards.

Is that one of those Windows built-in firewalls or a real one? With >firewall I was thinking of it getting overwhelmed by too many >connections.the firewall is in other computer.
How many connections per second do you get? If there are hundreds >it could still be listen queue. The default length is 50 (unless the OS >forces it smaller) which should be enough for most situations.In this moment, there are 183 connections, one in ESTABLISHED and the rest in CLOSE_WAIT, but today it doesn't produce the error. Per second it must have few connections.
Run "netstat -n". Are there tens of thousands of connections in >TIME_WAIT or something? Or just open sockets? Is there a related >error message in system log files (Unix) or Control panel -> >Admininstrative -> Event Viewer (Windows)? There aren't events in the viewer.
The server gets no >exceptions (you are careful to log everything)? I'm thinking of running >out of file/socket descriptors or socket buffers or something.When in the client appears this error, in the server doesn't appear anything
When you get the error does it start working after a while >automatically? I'm thinking if it is listen queue overflow that should >clear itself automatically.No, I have to close the program and open again. If the program detects it and intents close server socket and open directly, it produces Address already in use: JVM_Bind.
When the socket "breaks" run "telnet localhost ThePortNumber" on >the server computer - does it connect? Run "netstat -n" on the server, >is there a LISTENING entry for the socket?I probe the next time
I don't think server sockets suddenly somehow spontaneously break.Ok, it can reach the limit, but then mi question is how open again the server socket

Problem with Embedded OC4J: Address already in use: JVM_Bind

When I try to run a Servlet in JDeveloper 10g it works fine. But when I stop the Embedded OC4J and try to run the Servlet again, the following message appears in the log:

What could be causing this problem?
Thanks in advance!

Modify the config/rmi.xml file to have the host attribute in the tag as follows:
<rmi-server port="23791" host="server-ip-address">
</rmi-server>
After that, place the log4j-your-jdev-version.jar in appserverhome/j2ee/home/lib folder.
Restart the server. The bind problem would disappear.
Hope this solves your problem :-)

Address already in use: JVM_Bind error in DOS

Hello,
I am writing a multi threaded client server (Both client and server are multi threaded) program.where I have set of clients performing secure file transfer amongst them self. Here there is a Indexing server who is keeping record of all the files contained by clients. A client will make a request for a file to the Indexing Server which intern return the port no. and address of the client having that file. Now this client will connect to another client (Which now will act as server) to get the file and public key .
Now I am connecting to server by using fix port number.
Socket client = new Socket("127.0.0.1",2345)
Also since the request for file from another client can come therefor I am creating a thread to start listning port on client side by,
serverSocket serversocket = new serverSocket(client.getLocalport);
//provided that connection to server with port 2345 already made.
but when I am running this program through "DOS" it is giving me an error Address already in use: JVM_Bind.
//checked through netstat and found that localport for the client is bound to 2345 (That is obvious)
But when I am running this program in unix I am getting no error.

Sorry, to use such short forms in forums as i dont know much about this. i rarly use java forum. well, i removed the code that i gave u for server starting. but still it is giving me the same error. this time i put it in a java bean file.(Hint "u" is just another short form).
Did you try the suggestion to put a log statement just before you start the server? Or put a breakpoint at that line and see how often it is reached.
Because the only reason for this problem is that something is already listening at that port.
And if there's really nothing listening before you start you application, then only your application itself can listen there already, so the logical conclusion for me would be that you're starting the Server twice.

Error starting ORMI-Server. Unable to bind socket: Address already in use:

hi,
I run the folowing command "start_oc4j.bat" to start Oc4j.
It starts successfully.
Then I start "BPEL PM Server".
I get the following error,
"Error starting ORMI-Server. Unable to bind socket: Address already in use: JVM_Bind".
I understand the above errror because both of them are trying to bind to the same port. And both of them are trying to start ORMI server. Can some one suggest how to get rid of this problem.
I tried giving different port numbers for them, but that did not work. Let me know, how to over come this problem.
with regards
shaila

You may have another OC4J running on your computer.
You should change the port number in the file config/rmi.xml.

"BindException: Address already in use" error all the time!

I made a simple program that streams lines of text across the network/internet and a simple client program to display that text. The problem is, regardless of what port I choose, I always get this exception on the server's side:

Hi,
your Server must create only one ServerSocket, not multiples! So write
try{
    ss = new ServerSocket(49625);
    System.out.println("Bound");
    while(true){
      System.out.println("Started Listening");
      new LyricalThread(ss.accept()).start();
catch(Exception e){
    e.printStackTrace();
    System.exit(1);
}and take the creation of the ServerSocket outside the while-loop.

Web Service Client, BindException, Address already in use, saaj.SOAPExcepti

Hello,
Am caught up with an error and i can't get past it, need some help here.
My application is a batch processing web service client, reads some input rows, sends web service requets, processes the responses and logs it.
The application runs well in normal mode, but under load(more thread count), I get this wierd error and I can't make it go away.
java.security.PrivilegedActionException: com.sun.xml.messaging.saaj.SOAPExceptionImpl: Message send failed

I have properly closed the connections after each web service calls, but it still says Address in use. Please refer below for the complete stack trace and a piece of the code. Am using SAAJ and JWSDP and am not using AXIS api. I have searched the web but couldn't find any solutions.
This is not an error that server is not closing connections properly as I was able to test with SOAPUI and LoadRunner with even higher threads and it ran without problems. SOAPUI and LoadRunner scripts were executed from the same client machine as my application uses. Please help.
For each inputrow
SOAPConnection connection = null;
try
SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();
connection = soapConnFactory.createConnection();
SOAPMessage request = getRequest(inputRow);
SOAPMessage response = connection.call(request, "http://<<server>>:<<port no>>/Domain/Services/Mgmt");
finally
if (connection != null)
connection.close();
}catch(SOAPException se){

Move server socket creation out of while loop. You don't need to create new server socket every time.

Do you get the IP address is in use log message?

Socket Error: Address already in use

Hello all,
I'm trying to get the Trac bug tracking system installed on my system(running snow leopard). After quite a bit of tinkering I've managed to install Trac, but as of now, its a standalone entity. I am trying to get this linked to the apache webserver, but having no success. Has anybody done this before? I haven't used unix to this level before and so am struggling with that as well... any info on this is much appreciated.
One of the instructions to test run Trac as a standalone component was using this command tracd --port 8000 /path/to/myfolder (according to installation instructions at http://trac.edgewall.org/wiki/TracInstall). I stopped it using Ctrl-Z and now when I try to run it again, get the following message and error:

I realize that closing the terminal window "frees" the socket. But, is there something else that I can do while stopping the running application to ensure that the socket also gets "freed"?

Control-Z does "stop" the process, but it doesn't kill it. Use Control-C to do that. Then, you may have to wait a couple of minutes for the OS to free up your socket until you can try again.

Ftp (GNU inetutils) 1.6 error : [ftp: bind: Address already in use]

hi,
recently I discovered that I cant connect to many ftp servers using the common command line ftp client from a 64bit archlinux box.
I tried connecting from other PCs at the same network (iMac) and it works without problems, the error is general, shows with every ftp server I tried,
the client connects and then freezes or returns an error (depending on the ftp server)
ftp: bind: Address already in use
I got no firewall or iptables rules, I installed ncftp with pacman and it works, so I assume it's a ftp (GNU) client error,
thanks

Address already in use: connect

Dear all,I've got always this following exception, if I get three times the method getDimensionTree. This method simply reads one dimension tree in Essbaseand constructs a DataTreeModel (like JTree) with the member names.The source is like a sample code from Hyperion, but whyever it is crashing using the EES 6.5 with Essbase 6.5.3.I believe, that the connections aren't removed. But however the getConnections-iterator is always returning null. And I debug the logsbefore and after a connect and disconnect, to be sure everything is closed.I tried this with Essbase 7.0 and EDS 7.0 and it works perfect, but I am not allowed to use the version 7 because of other tools combination. There I am using the m_olapServer.connect(true, false), whichis not available at the 6.5 JAPI. Therefore there is apublic void connect(boolean useEesSvrAtOlapSvrNode) throws EssException with useEesSvrAtOlapSvrNode - If true, the enterprise server at the node where this olap server resides is used to traffic the requests between the JAPI client and the olap server. If false, the enterprise server that authenticated the user is used to traffic the requests.but I cannot understand the sense of the parameter flag.

Address already in use

Hi Guys!
I'm using Oracle9ias 9.0.3. When I execute
$opmnctl startall, I get the next error in all instances (<instance>.default_island.1):
java.net.BindException: Address already in use
at java.net.PlainSocketImpl.socketBind(Native Method)
I have 3 instances, each one with different port rmi, configured in opmn.xml.
I used -Drmi.debug=true -Drmi.verbose=true in java-options and I got in the log:
RMIServer.DEBUG: using OPMN, address is ZERO_ADDRESS, use local address instead
RMIServer.DEBUG: creating RMIServer ServerSocket for address: antares.txp/127.0.0.1 port: 3114
RMIServer.DEBUG: Launching RMIServer thread
RMIServer.DEBUG: creating RMIServer ServerSocket for local address: antares.txp/127.0.0.1 port: 3114
at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:447)
at java.net.ServerSocket.<init>
Any idea??
Thanks!

Try to use netstat -an to see if there is anything listening on this port (you should see "LISTEN" on far right on line). There is no process id or whatever, you just know there is a server socket open - might be a different program, might be a running instance incorrectly shuted down...
On the left there is a local address, on right there is a remote address (might be a connection from the same host, of course)
If there is nothing running before starting server, there is probably a port mismatch in your settings (i. e. rmi port for next started instance is the same as jms or http port of prevous one... I don't know about all of the ports settings.
Sometimes, especially on Windows there is a situation when server socket is not correctly closed and you have to restart Windows itself.
