Getting "connection refused"
Hi,
I just started looking at Oracle CEP. I created a simple Helloworld project that uses a built-in Pub-Sub adapter. I am facing the following problems:
1. I am getting "Connection Refused" when I add/publish the project to Oracle CEP server. I am using port 9102 on Windows XP server.
2. I am not able to find any decent client example that I can use to access this flow. I tried Dojo Bayeus client example but these are pieces
here and there and most of them are outdated, can somebody please provide a sample code for Async client?
3. I tried to create a custom Adapter as servlet instead of using pub-sub but I am not able to find full documnetation on how to deploy a servlet or register
it in Oracle CEP, I could not find anything on how to do this looking into different OSGi, Spring and Oracle sites.
Any help is highly appreciated.
Thanks,
Firas

I tried to activate Mozilla Firefox today using the normal & routine method, clicking on the Firefox Icon.
Each time I tried I got the same message "Connection Refused".
I went to the Firefox site and read the message regarding disabling Java, so I opened ADD ONS and Plug Ins and disabled Java.
Still no change, so I shut down and restarted my computer.
I keep getting the same Connection Refused message.
What needs to be done to restore Firefox?Another user also reported a problem with the AT&T Yahoo home page in the past few minutes. When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
orange Firefox button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
Then try reloading the page. Does that help? -
[SOLVED]dbus and systemd: "systemctl --user" gets "Connection refused"
Hi,
I want to enable some systemd user service. Here is what I get
$ LANG=C systemctl --user
Failed to get D-Bus connection: Connection refused
$ echo $DBUS_SESSION_BUS_ADDRESS
unix:abstract=/tmp/dbus-RboLZS2wF3,guid=feb8bd85248906d12a826acd54e3c4ad
I don't believe I've ever touched dbus, so I'm a bit lost. There's the following line in my ~/.xinitrc:
exec dbus-launch xmonad

How to send a file without getting Connection Refused??
Hello everyone!
I'm developing a FTP (Client and Server) program as a project and I have 2 main problems:
1. The program can't connect to computers with router (Connection Refused error)
2. If a computer with router connects to me, the program will not transfer the file (Connection Refused error again). but if it does, my friend's internet is suddenly disconnect after one transfer
what should i do?!? : //
everything is working well on one computer, but when i'm trying to work on 2 computers its screwed
***FOR EVERY TRANSFER I OPEN A DIFFERENT SOCKET AND CLOSE IT (AND ALL THE OTHER STREAMS) IN CASE OF EXCEPTION OR COMPLETION

How does FTP work normally? Well in most cases you are talking to a server that is on the internet. This server has been configured to be behind or on a network where the routers are not blocking requests to connect to FTP ports (among other services). So nothing different other than it is configured correctly.
I do suspect your program may have some bugs as well. For example when you talk about it dropping the connection after one transfer. That doesn't sound too great.when i checked the program...no
in the test...yes
so the server has no blocking ports, but what about a client with a router?..how do the programs pass the client blocking?
when i checked the program with a friend (i have a modem and i was the server) all the data was perfectly transfered (moving among folders, deleting files, creation of folders-->all these actions on the server..sending codes, strings and stuff), but when i tried to transfer a file it did connection refused :S
i can bring a link to the file that do the transfer and if you have patience to read -

I'm not sure what port to connect to as SQL2005 port shows 0
which apparently means dynamic port allocation.
When I try port 1434 I get connection refused.
I have user name set to sa (and this is enabled in SQL2005)
and no password (windows authentication). Same result if user name
is blank.
Anyone got any idea what these settings should be?
DougI have now switched off dynamic port allocation and changed
the port to 1435 and I think I now connect to SQL Server 2005, but
I now get the error:
The user is not associated with a trusted SQL Server
connection.
I have tried using sa and tried setting up another user name,
but cannot get past this error.
Any help would be appreciated.

Connection Refused Error In Connection Client
Hello Geeks
I am runnig a RMI application in which runs on internet , i have setup RMI server on a host server and it is running there.
Now, when i try to call client using ip address of the Host , i am getting Connection Refused error.
Example :
Registry registry=LocateRegistry.getRegistry("70.33.246.110");
System.out.println("Above connectMe");
String serverName = "rmi://70.33.246.110:2786/connectUser";
connectMe stub=(connectMe)Naming.lookup(serverName);
System.out.println("Below connectMe");
boolean log=stub.login(username,password,1);
System.out.println("Below login");Here "connectuser" is name i have given in server to which client lookups.I am getting -> Above connectMe and Below connectMe
but then i am getting connection refused error.
Please Help Me Out.....ASAp
Edited by: Hardik.Mishra on Oct 3, 2009 5:46 PMRegistry registry=LocateRegistry.getRegistry("70.33.246.110");There's no point to doing that ...
System.out.println("Above connectMe");
String serverName = "rmi://70.33.246.110:2786/connectUser";
connectMe stub=(connectMe)Naming.lookup(serverName);... if you're doing that. The getRegistry() doesn't do a network operation, it just constructs a stub to that Registry locally. Only by using it would you find out whether it meant anything: and you're not using it.
I am getting -> Above connectMe and Below connectMe
but then i am getting connection refused error.See item A.1 on the RMI Frequently Asked Questions list in the Javadoc. -
"connection refused" in Safari
Recently uninstalled Safari "Ad-block" extension. Now I am getting "connection refused" errors when trying to access some web pages. Can someone help!
I know there's an uninstall button in Safari / Preferences - Extension but just in case...
Go to ~/Library/Safari/Extensions
If the Adblock extension is in the list, move it to the Trash.
~ (Tilde) character represents the Home folder.
For LIon: To find the Home folder in OS X Lion, open the Finder, hold the Option key, and choose Go > Library
And sometimes restarting your Mac after you uninstall an Extension helps. -

Connection refused in Mission control
Hi !
I created a simple application just for demo and I start it with
java prim.Prim 100000000 -XX:+UnlockCommercialFeatures -XX:+FlightRecorder
But I can't connect, when doing 'Start jmx-console' I get connection refused after a while.
The same problem when starting the application in NetBeans .At least that makes sense (JConsole not working either). Okay, so something is messed up regarding local attach on your machine. Let's try not using local attach. What happens if you try adding the following to the command line, and then set up a connection in JMC manually (click the "new custom connection" icon in the JVM Browser)?
-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=7091 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -
Connecting from outside - Connection refused
Hey,
I am trying to connect to my home computer using VNC / FreeNX.
When trying to connect from inside the home network, everything works OK (using the internal network IP).
But, when trying to connect to the same computer using its internet IP, I get "connection refused".
Please note that I use a router for my home network, and I have DMZ enabled to the desktop computer.
I know that DMZ works OK (checked it with aMule).
hosts.allow and hosts.deny both contain nothing.
Tnx
FiodCheck the logs on the box you're trying to connect to - you should be able to determine whether the connection attempt reached it and was rejected for some reason, or didn't reach it at all. In the first case, the log messages should give you some idea on how to fix it; in the second case, the problem would be on your router.

Socket mostly times out, connection refused.
Hello,
I am writing my own version of dc-hub in Java. This is my first networking program I make.
The main class has a ServerSocket running on port 411 and it will then make another socket when someone connects. Although at the moment 198 users are connected, it seems that the server mostly gives a time out when you try to connect. It's not a firewall problem, because I get them (localhost) as well. The server also runs on localhost.
This is the code:
ServerSocket serverSock = new ServerSocket(411);while(true) { Socket sock = serverSock.accept(); new ConnectorThread(sock,P,U);}
I really have no clue why I and a lot of other users get time outs...
I'll post the results from the client program (DC++):
[17:39] *** Connection refused by target machine
[17:39] *** Connecting to localhost...
[17:39] *** Connection refused by target machine
[17:39] *** Connecting to localhost...
[17:40] *** Connection refused by target machine
[17:40] *** Connecting to localhost...
[17:40] *** Connected
[17:40] <Hub-Security> Welcome to Tom's personal hubsoftware V1.0
Oh... yeah... I get Connection refused, while my friends are receiving "Connection time out..."
Again: It's not a firewall or router problem... I know that 100% sure...
I hope someone knows how to fix this problem, I've searched the forum without a result for my problem.
Thank you in advance,
TomI am running 1.4.2_05 on win2000

Bluetooth Connection Refused obex
I have succesfully paird my htc hero (running cm7) and my lg saber. When i try to send a file I get connection refused. I am using blueman. I have tried using obexftp from command line and i get this output.
obexftp -b B0:89:91:53:CC:EA -p wavycurls.jpg
Browsing B0:89:91:53:CC:EA ...
Connecting...failed: connect
Tried to connect for 200ms
error on connect(): Permission denied
Still trying to connect
Connecting..\done
Tried to connect for 123ms
Sending "picture.jpg"...-done
Disconnecting..\done
From command line, this does send the file. I presume the front end halts at the permission denied error thus never sending the file. I have other problems interfacing/ browsing my devices but I think they may be related to this and I am unfamiliar with bluetooth neuances in linux.
I am sure this is a linux software/config issue because if I reboot into my hackintosh partition I can send and browse fine, at least with my lg saber.
Any help is appreciated since I cannot find a solution via google.I have gvfs-obex installed, not sure about gnome-polkit. I tried on my desktop with the same bluetooth adapter and got to browse my phone. I had to connect using a bluetooth app on my android phone. If I tried to connect from the computer side and it crashed my phone, but I'm not sure that has anything to do with linux. I have arch installed on both computers. gnome-polkit not installed on desktop. gvfs-obexftp is installed and works with pcmanfm on desktop.
