acastanheira2001 Sep 10, 2008 12:55 PM (in response to acastanheira2001)Hi Peter,
I´m looking for a file that logs jmx-console´s info, but I didn´t find.
What is the name and path of the jmx-console log file?
Thanks again,
Andre -

peterj Sep 10, 2008 1:22 PM (in response to acastanheira2001)JBoss AS logs information to two locations. First, to the console. Second to the file server/xxx/log/server.log. The console log output would be the best - the server.log tends to be verbose.

Whenever I hit http://myserver:8080/jmx-console/ it throws in server.log the following:

peterj Sep 12, 2008 3:35 PM (in response to acastanheira2001)What version of JBossAS are you using? It would appear that some security settings have been made - I would not expect this error from an out-of-the-box deployment of the community editions of JBossAS.
What happens if you enter: http://myserver:8080/ -
6. Re: jmx-console - blank page return
acastanheira2001 Sep 12, 2008 4:29 PM (in response to acastanheira2001)Peter,
I use Jboss 4.2.0 GA.
When I enter http://myserver:8080/ it shows the "Welcome to Jboss" page. -
7. Re: jmx-console - blank page return
peterj Sep 12, 2008 5:11 PM (in response to acastanheira2001)Are you using the community version of JBossAS, or the enterprise version (EAP)? Please line in the console log that looks like this (it is the second line in the log):
08:57:12,482 INFO [Server] Release ID: JBoss [Trinity] 4.2.3.GA (build: SVNTag=
JBoss_4_2_3_GA date=200807181417)
You can also find this line in the server/xxx/log/boot.log file.
If you are using the community version someone has changed the security settings and done so incorrectly. Could you try again with a clean install of JBossAS? -

acastanheira2001 Sep 15, 2008 9:46 AM (in response to acastanheira2001)Peter,
Here´s the info from boot.log:
11:53:27,175 INFO [Server] Release ID: JBoss [EAP] 4.2.0.GA_CP02 (build: SVNTag=JBPAPP_4_2_0_GA_CP02 date=200801291544)
My team mates installed jboss on another CPU. The error remains on both servers.
Any ideas? -
9. Re: jmx-console - blank page return
peterj Sep 15, 2008 11:08 AM (in response to acastanheira2001)As I suspected, you are running JBossEAP, not JBossAS. With JBossEAP, everything is locked down, and it is locked down in such a way that you cannot sign in unless you make some configuration changes.
Uncomment the "admin=admin" line from the server/xxx/conf/props/jmx-console-users.properties file and then try again. (Hope this is correct, I am writing this from home and don't have a copy of EAP here to verify the file name and contents.)
Also, if i recall correctly, the readme file has information on configuring the security settings. -
10. Re: jmx-console - blank page return
acastanheira2001 Sep 18, 2008 4:02 PM (in response to acastanheira2001)Peter,
The line is uncommented.
Do you think is it related to the following topic? http://www.jboss.com/index.html?module=bb&op=viewtopic&t=106353
Thanks,

11. Re: jmx-console - blank page return
peterj Sep 18, 2008 9:21 PM (in response to acastanheira2001)I do not think that topic relates to what you are seeing.
Because you have EAP, you must have a support contract, and that contract should come with a support contact. I suggest you make this issue known through your support contact.
When I use EAP, if I uncomment the admin=admin line, when I go to the jmx-console, the browser displays a login dialog and once I enter admin/admin, I see the jmx-console home page. Other than reinstalling, the only other thing I can suggest is contacting support. -
12. Re: jmx-console - blank page return
peterj Sep 18, 2008 9:24 PM (in response to acastanheira2001)A few more thoughts.
What operating system are you using? There is a line in the console log that identifies this.
How are you starting JBossEAP? Via the run script, or as a service?
What JVM are you using? There are lines in the console log file that identify this. -
