Connect to JBoss AS 7 on Oracle Linux 7 in VirtualBox

[Edward Bloom]

Howdy!

I installed the Oracle Linux 7 in to the VirtualBox. This is a standard installation, I did not configure anything.
The virtual machine network is attached to Bridged Adapter.

With winscp I copied the jboss-as-7 and the java to /usr/etc path.

> [root@localhost ~]# export PATH=$JAVA_HOME/bin:$PATH

After this, I tried to connect with my Host machine to the Guest server with this link http://172.24.131.35:8080/MyExample/
But it is not connect.

What could be wrong? In the Linux or in the standalone.xml? Or my virtual machine installation in VirtualBox?

The JBoss AS 7 is a standard install too.

Here is the console log.

08:45:51,486 INFO [org.apache.coyote.http11.Http11Protocol] (MSC service thread 1-2) Starting Coyote HTTP/1.1 on http--127.0.0.1-8080

By default, all services including the HTTP listener services are bound to localhost (for security reasons). So you can't access the server remotely unless you specify which IP/host the server's services are to be bound to. One of the ways to bind to a specific IP which is then remotely accessible is by using the -b option (there are other ways to do it via the standalone/domain xml configurations too) to the startup command:

./standalone.sh -b <IP-to-bind-the-services-to>

In your case it would be:

./standalone.sh -b 172.24.131.35

There's more details in this blog that I wrote up when the -b support was added in AS7 http://www.jaitechwriteups.blogspot.in/2011/09/jboss-as-702-arc-released.html

Dear Jaikiran Pai,

I've tried your suggestion.

And I've tried also this one:
./standalone.sh -Djboss.bind.address=172.24.131.35 -Djboss.bind.address.management=172.24.131.35

and this one in the standalone xml:
<interface name="management"> <inet-address value="172.24.131.35"/> </interface> <interface name="public"> <inet-address value="172.24.131.35"/> </interface>


But unfortunatelly i cannot reach yet.

[Jaikiran Pai]

Make sure the firewall rules allow access to that IP/port from outside. You could even try a simple:

telnet 172.24.131.35 8080

from the command prompt and see if that works (of course after starting the server). If it doesn't then you'll have to check with the sysadmin about the firewall rules.

[Edward Bloom]

Dear Jaikiran Pai,

I typed that command on my Oracle Virtual machine.
The result of your suggestion:

[root@localhost ~]# telnet 172.24.131.35 8080
Trying 172.24.131.35...
Connected to 172.24.131.35.
Escape character is '^]'.

Edit:
And when i shut down the JBoss As:
Connection closed by foreign host.

I suppose thats right.

I turned off firewall on the windows 8.1 host too.

[Jaikiran Pai]

Did you try the telnet from the same machine from where you weren't able to access the server?

[Edward Bloom]

The problem was the firewall on the Oracle Linux 7.

So i had to stop and disable firewalld using systemd.

systemctl stop firewalld.service
systemctl disable firewalld.service

Thanks,
