Publisher cannot publish message

[weite]

I'm a noob to JBoss and log4j. I have been trying out to use log4j for my application in JBoss. I have written a simple program to send some logs thru JMSappender. However the behaviour of the publisher has been rather unpredictable. I have rewrote JMSAppender which I basically put some println statements to trace thru. The problem with my publisher is that sometimes it basically hangs before the line where it tries to do a publish(message). I'm not sure why it hangs there and yet it works sometimes. Any help would be appreciated.

Here's my configuration file used:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">




<!-- The default pattern: Date Priority [Category] Message\n -->













<!-- The default pattern: Date Priority [Category] Message\n -->





<appender-ref ref="CONSOLE"/>
<appender-ref ref="JMS" />


</log4j:configuration>


Here's my program doing the logging,

import org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;

public class Helloworld{
static Logger logger = Logger.getLogger("Helloworld");
static public void main(String[] args){
DOMConfigurator.configure(args[0]);
logger.info("Entering application");
logger.info("Exiting application");
}
}

here's some of the output i got from the console, not sure if its helpful

It is waiting for the client to connection back to you
because you are using OIL. What error do you see on the server?

Is there a firewall in the way?

I do not get to see any errors on the server side until I do a Ctrl-C on my publisher.

Server error from console:
22:30:23,771 INFO [Server] JBoss (MX MicroKernel) [3.2.1 (build: CVSTag=JBoss_3
_2_1 date=200305041533)] Started in 19s:508ms
22:38:33,886 ERROR [OILClientIL] Cannot connect to the ConnectionReceiver/Server

java.net.SocketException: Connection reset
at java.net.SocketInputStream.read(SocketInputStream.java:168)


I do not have any firewalls running. I'm running the publisher, JBoss and the consumer on the same machine. I do not understand sometimes it works perfectly without any errors by just retrying the publisher program again and again.

Is the OIL thing important in understanding how it works? I'm a complete newbie in this. Thanks for any input!! :)

[adrian.brock]

OIL connects back to the client from the server.
This is where it is hanging.
Try UIL2.

Just because you are on the same server doesn't mean
the firewall won't get in the way.

Some OSs like Redhat install a firewall by default.

I've made the change to my config files with this line:


Is there anything more I need to change?

I've tried my publisher again with the changes and it seems to be locked up before doing publishing again.

It sits and wait at this line:
320 [main] DEBUG org.jboss.mq.GenericConnectionFactory - Handing out ClientIL:
org.jboss.mq.il.uil.UILClientILService

There's no new log being displayed at my JBoss console until I do a Ctrl-C on my publisher.

This is what that has been dumped out:

I'm currently using Win2K and I haven't install any firewall packages on my machine.

Thanks.

And the DEBUG message in log/server.log is?

[adrian.brock]

Ah! I didn't read your response.

This error is thrown when it cannot get socket streams.
It is hanging on the socket open for some reason?

Adrian

[weite]

I've tried using UILConnectionFactory and UIL2ConnectionFactory. Anything else I can try? It seems that OIL has higher chance of connecting while UIL or UIL2 has zero chance of connecting.

[adrian.brock]

On your previous report you got a RemoteException.
In server/default/log/server.log there will be a DEBUG
message that shows the real SocketException

I've finally got my logging application to work by using RMIConnectionFactory. Does that mean that OIL and UIL are broken?

Regarding UIL,

these are the errors thrown on the server log when I do a CTRL-C on the publisher:

09:53:28,542 ERROR [SocketManager] Failed to create ObjectInputStream
java.net.SocketException: Connection reset
at java.net.SocketInputStream.read(SocketInputStream.java:168)


If I sit and wait, time out occurs:
09:54:48,837 ERROR [SocketManager] Failed to create ObjectInputStream
java.net.SocketTimeoutException: Read timed out
at java.net.SocketInputStream.socketRead0(Native Method)

[adrian.brock]

Like I said before, it cannot read from the socket.
It is the same problem for both OIL and UIL

I've got no idea why it cannot read from the socket?
It isn't a firewall problem otherwise RMI wouldn't work.

Adrian
