jmx-console returns only a blank page

johnsonlau Jul 20, 2004 3:24 AM

Why ?

http://localhost:8083/index.html may show and it's ok. But I click "Jmx console" or "Web console" will return a blank page.

Why 8083, what about 8080?

I am also having this problem.. ./run.sh -c all -b 192.168.1.12 starts the server.

:14:04:59,696 INFO [Server] JBoss (MX MicroKernel) [4.0.2 (build: CVSTag=JBoss_4_0_2 date=200505022023)] Started in 38s:576ms

But it binds to port 8083 and when accessing with browser displays a page who's source just has the following:

Port 8080 remains closed.

Java VM: Java HotSpot(TM) Server VM 1.5.0_03-b07
OS-System: Linux 2.4.25-1-386,i386

Possible issue:
19:05:26,263 WARN [ServiceController] Problem starting service jboss:service=Naming
java.lang.NoClassDefFoundError: javax/net/SocketFactory

Any ideas?

Port 8083 is the class download service. You want port 8080.

I get connection refused on 8080

No other app is bound to 8080 before server startup or after.

on ctrlC I get the following:

08:41:16,023 INFO [Server] JBoss SHUTDOWN: Undeploying all packages
08:41:16,260 INFO [HypersonicDatabase] Database standalone closed clean
08:41:16,951 INFO [SnmpAgentService] SNMP agent stopped
08:41:17,408 ERROR [HttpInvoker] Failed
java.lang.NoClassDefFoundError: javax/net/SocketFactory

Where can I look; what can I look for to determine what is going wrong?

Have you tried: -

http://192.168.1.12:8080/

Yes,

Here is how I tested:

debian:/opt/jboss-4.0.2/bin# telnet 192.168.1.12 8080
Trying 192.168.1.12...
telnet: Unable to connect to remote host: Connection refused
debian:/opt/jboss-4.0.2/bin# telnet 192.168.1.12 8083
Trying 192.168.1.12...
Connected to 192.168.1.12.
Escape character is '^]'.

I know 8083 is being bound by jboss because connection is refused if I shut down the server.

Have you been through the log produced when JBoss was started to see if any errors were reported?

Yes, I have looked at the log and redirected the startup to a file for viewing, but I do not know what to look for in so much information.

I see some messages which seem to be a concern but in the end, the server does start and is running.

Here is a message which is a warning... but is it critical or pertain to my problem... or normal... I don't know:

09:07:29,490 WARN [ServiceController] Problem starting service jboss:service=Naming
java.lang.NoClassDefFoundError: javax/net/SocketFactory

Is there a regexp I can use to grep out applicable messages?
