Administration Console does not load and is showing a blank page on 7.1.0

andy.thomas Feb 18, 2012 12:37 PM

I've been trying to install Jboss 7.1.0 on my Linux VPS (Webfusion) and for some reason JBoss installs fine and I can load it as a standalone and even run it up automatically when I re-start my server. However I can only see the frontpage on port 8080 but when I click on the Administation Console link I just get a blank page. I've tried Safari, IE, Firefox and Chrome.

If I install a local version of 7.1.0 on my iMac, no problems at all and it all works fine

My env setttings are all correct and when I manually run up standalone.sh to see what happens in a console I dont see any stack trace errors.

Any pointers for a novice would be great, hopefully it's something stupid I've missed

Thanks

Andy

Hey Andy,

by default the admin console is at "127.0.0.1:9990" (localhost). Which means that it wont be accessible from outside of that machine. You can control where to bind it by setting /bin/standalone.sh -bmanagement=192.168.0.10 (but note the security implications).

Either way the blank screen seems odd, make sure you can make connections to that machine on that port (ie. firewall). [You could also try to ssh -X with forwarding X and run browser from the server machine.]

Hi

Thanks for the reply, really appreciate it

I just can't seem to make it work Im afraid, not 100% sure I understand what you mean

I use this command sh standalone.sh -b 0.0.0.0 to get it going because it's a remote server. It's a VPS hosted by Webfusion not a local machine i.e. I'm not trying to access my local machine remotely, I'm trying to access a remote JBoss installation on a VPS from my local machine

What does the -bmanagement=192.168.0.10 do? When I tried to use that it failed to load, I guess because of the IP Address

The documentation around hosting JBoss on something other than a local machine is really hard to understand as a newbie. I was hoping it would be just a simple configuration setting in the standalone/configuration/standalone.xml file but I cant find anything telling me how to do it

Thanks

I've also tried this as a startup command

sh standalone.sh -b 0.0.0.0 -bmanagement 0.0.0.0

Still no joy

Hi Andy,

since AS7 the administration of the server is separated from 'normal' application.
-b <1.2.3.4> bind the 'application server' against an interface, so you can access your application with http://1.2.3.4:8080 also all other application relevant connections i.e. JNDI.

-bmanagement <9.8.7.6> bind the 'management server' against an interface (127.0.0.1 is the default)
now you can access the JBoss management console via http://9.8.7.6:9990, alos the native interface for CLI and domain mode is bound against this interface!

If you use the command from your last post you should use 'http://<your IP address>:9990' to see the management console.

Do you see something like this if you start the server (I start bin\standalone.bat -bmanagement 1.2.3.4) :
INFO [org.jboss.as.remoting] (MSC service thread 1-1) JBAS017100: Listening on /127.0.0.1:4447
INFO [org.jboss.as.remoting] (MSC service thread 1-5) JBAS017100: Listening on /1.2.3.4:9999

If yes it should work with http://1.2.3.4:9990

Do you start a fresh unzipped server?

Blan-blank I think. this is what Firebug gives me for the page (I've taken out the IP address)

<!DOCTYPE html>

<head>

<title>JBoss Management</title>

<meta content="text/html;charset=utf-8" http-equiv="content-type">

<script src="app/app.nocache.js" language="javascript" type="text/javascript">

Reload the page to get source for: http://?.?.?.?:9990/console/app/app.nocache.js

Hmm, looks that the server provide the page.

But do you have restricted access for javascript?

Hi

I've got JavaScript enabled, and I've tried it on IE, Chrome, Safari and Firefox :(

I'm wondering if it's some port setting on my VPS? but I have no clue how to fix that or even where to start. I tried JBoss 5.1 as a test on my VPS and all was fine

Hi

Sorted finally. Thanks for all the pointers.

I'm using VirusBarrier X6 and had WebThreats turned on. As soon as I turned it off all was fine, sorry to bother everyone but it was user error :(

Thanks again for the feedback it helped put me on me right track to time root cause
