on bind address, business central is running but I cannot find any execution server
but when I run the same command without bind address like
./standalone.sh -c standalone-full.xml
All are working properly
What would be the issue when using bind address
I'm using

I am trying to use Wildfly/JBoss to deploy a war of a program I made, but I keep receiving the following errors when I try to connect:

What I did were the following steps
1)Went to the Wildfly site
2)Downloaded the latest version of the standalone
3)Unpacked from the archive
4)Run on Windows the file jboss-cli.bat by double clicking on it
5)Typed what you can see above (and before that I also typed only "connect", without anything else. Still didn't work, same error for localhost:9990)
I must specify this is a clean download with no configuration changed, no file deleted, nothing modified at all. Not even the war was deployed. I also tried to add a rule to the Windows firewall to unlock the port 9990, still the same error. On port 9990 nothing is listening, I already checked in cmd. And I also restarted my PC before trying the connect commands, so nothing would be opened by me on that port.
I have the latest versions of JDK and JRE installed on my PC if that helps.
What is going on with this error, I am really lost.
In the end I fixed the problem, and the solution was pretty straightforward. I forgot to open standalone.sh so wildfly can run, this being the reason jboss didn't connect.
I was trying to follow some EJB tutorial, most of them started talking about JNDI, and I am having trouble to get the service running on the JBOSS AS.
I have tried both the community and EAP version of JBoss in Eclipse, but both fails.
So now whenever I run lines like BeanRemote beanRemote = (BeanRemote) context.lookup("somecontext"); it throws these error.
javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]

well of course it is caused by the port not opened, but I think its because the Jboss server is not providing the service, although its web port and admin port 8080 and 9990 is working fine.
I am using eclipse Oxygen 4.7.0, I have downloaded the Red Hat JBoss developer Studio. I added the server via the "New Server" wizard, then downloaded the server runtimes within the wizard. However there just seems no way to configure jndi, nor can I find any file that is related to jndi or jnp in the downloaded path. The XML configuration showed that only Management 9990 and Web 8080 port is open.
I don't understand why is this not enabled by default, and I don't know what to do. Is JNDI configurable somewhere in the management console? please help
Turns out method of linking to jndi changed in EAP 7 from EAP 5
this articles shows the correct method.
jndi.properties has been changed to jboss-ejb-client.properties, and the standard config now becomes
endpoint.name=client-endpoint
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=yourhostaddress
remote.connection.default.port = 8080
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
and context lookup string has been changed to
ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-the-remote-interface>
I have Wildfly 10 running on a docker swarm cluster. All HTTP requests go to a Load Balancer (traefik). In traefik (btw. labels in docker stack yml, it works perfectly) app.wildfly.my.swarm on port 80 redirects to the Wildfly container's 8080 port and admin.wildfly.my.swarm on port 80 redirects to port 9990. In my browser everything is working fine.
But if I try to use the maven wildfly plugin for remote deployment it fails with:
[ERROR] Failed to execute goal org.wildfly.plugins:wildfly-maven-plugin:1.2.1.Final:deploy (default-cli) on project automat: Failed to execute goal deploy. java.net.ConnectException: WFLYPRT0053: Could not connect to remote+http://admin.wildfly.my.swarm:80. The connection failed: XNIO000816: Redirect encountered establishing connection -> [Help 1]
Only if I open the management port directly it works.
Is there anywhere configuration needed to be able to deploy remotely with maven wildfly plugin to wildfly which is behind a proxy?
EDIT:
If trying to connect with CLI:
./bin/jboss-cli.sh
You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.

I am able to connect to the DB through the application deployed in BlueMix.
How are you populating the connection credentials? The application will have access the VCAP_SERVICES when run on Bluemix, but unless you have specifically copied that environment variable to your Eclipse environment, that information will not be available to your application.
The error indicates that the connection was refused. This most likely means that the host and port combination you've entered is incorrect. You'll want to ensure that you can connect to the host.
You can check that your local system can connect by doing nc -vz xxxxx.dblayer.com 10000 where xxxxx.dblayer.com is the full hostname provided to you within the variable and 10000 is the port, also provided.
It seems as though your syntax/configuration may not be correct as a connection being refused would indicate that it cannot connect however it's not clear from your post what hostname/port it's actually trying to connect to.
