created management user(admin)
opened jconsole.bat from wildfly/bin directory
tried with service:jmx:remote+http://wildfly_host_ip_address:9990

I'm using jboss 7.2,and I created a log4j2.xml and placed in the server, application running in the domain mode there are two server instance in each ip, application logs are printing only for one server instance and another server instance logs are not printing,how to print the both server instance logs are in separate files.
Is anyone having idea pls help on this.
Sorry....you cannot use log4j2 in JBoss7.2.
Only WildFly 22 supports Log4j2 out of the box.
However, you may implement Log4j2 to other versions of WildFly, according to this tutorial. However I did not try myself.
I have ActiveMQ Artemis server installed on a Unix box. I am able to create an Artemis broker instance which provides me with link to web console which is running on localhost.
Now I want access web console from an external machine, probably running Windows.
Can you please guide me on step by step process to configure the ActiveMQ Artemis server so that I can access it from another machine?
The embedded Jetty web server which is used to host the web console is configured in the bootstrap.xml file in the etc directory of your Artemis instance. Look for the web element in that file. You'll need to change its bind attribute to use something other than localhost since localhost is only accessible from the machine where the server is running. Typically this will be the externally accessible host name or IP address of the server.
You can find more information about configuring the embedded Jetty web server in the Artemis documentation.
Background
I am using the Oracle JDeveloper Studio with SOA installed as my IDE. In JDeveloper I want to create a connection to a remote Weblogic server.
The remote server is running on my local machine, and I refer to it as remote to distinguish it from the Integrated Weblogic Server that comes with JDeveloper.
After reading this answer I attempted to add the following lines to the Windows 10 host file:
#
127.0.0.10 localhost2
::1 localhost2
These two pictures show the Application Server setup in JDeveloper: Picture 1, Picture 2
However I still receive the following error:
Server excetion is :
Connection refused from server
When create new server on random port such as 7013 and 7014 for ssl, test connection return:
Testing HTTP Authentication ... failed
Connection refused: connect
Testing JSR-160 Runtime ... failed
Cannot establish connection.
Testing JSR-160 DomainRuntime ... skipped
Testing JSR-88 ... skipped

Testing JSR-88-DEP-MGR-LOCAL ... skipped
Testing JNDI ... skipped
Testing JSR-160 Edit ... skipped

Can anyone suggest some troubleshooting steps here?
Clarification
I need to clarify a few points to guide you to the correct answer.
Are you sure this is a separate Weblogic server running on localhost, not the Integrated Weblogic Server?
Are you sure the Integrated Weblogic server is not running?
Are you sure the Weblogic server you are attempting to connect to is running?
Troubleshooting
General Recommendations
Always run JDeveloper as Administrator
Located an utilize the *-diagnostic.log file and the standard out file
Utilize the JPS utility to see if the WLS process is running
Utilize the EM console to see what interface your server is listening on
Integrated Weblogic or Standalone Weblogic
Firstly, because you are new to Oracle SOA I need you to clarify if you have a Weblogic server installed locally separate from your Oracle BPM Studio ( JDeveloper ) IDE.
When creating a local SOA environment, JDeveloper comes with an Integrated Weblogic Server pre-installed. You don't need to install the Weblogic server separately.
To determine if you have a standalone Weblogic server installed on your local machine you could do a few things.
Do a search for startWebLogic.cmd. If that file is somewhere other than beneath %APPDATA% you likely have a standalone server
Secondly, with 11g ( maybe 12c ) you can check Add or Remove Programs to see if the installation is listed
You could also check to see if it's running by running a jps command in command prompt. This shows all Java processes currently running, and your Weblogic server runs as as a Java process. It will look something like the following
If you see a suspicious process you can run a jinfo <pid> to get more information about the process
You can also check Windows Services to see if you have a Weblogic service.
Most likely you don't even have a local Weblogic installed separate from JDeveloper's Integrated Server. In that case, please read the following section.
Integrated Weblogic Server
As stated before when you download Oracle BPM Studio ( JDeveloper with all the SOA plugins ) it comes with an Integrated server.
You first need to create a default domain and connection to this server.
First, open the Application Server panel.
You should now see the Application Server panel to the left side of your IDE
Remember, generally you are not installing the server here, you are just connecting to a server that is already installed from your IDE. The purpose being that you can deploy composites directly to the server from JDeveloper. Configuring the Integrated Server is a bit different, but the difference doesn't need to be explained here.
Right click on "Application Servers" and click New Application Server. This will display the following popup
Now walk through the steps of creating the default domain and server connection
Then test and finish. You should not have an integrated weblogic server running. To start the server you simply run -> Start Integrated Weblogic Server
If you Windows -> log you can see the server stdout and stderr rolling.
On windows you can also find these logs on Windows 10 by navigating to %APPDATA%\Roaming\JDeveloper\system12.2.1.3.42.170820.0914\DefaultDomain\servers\DefaultServer\logs in your system's file explorer.
Standalone Server
If for whatever reason you aren't using the Integrated Weblogic Server and instead have a standalone installation of Weblogic on your local machine you would first need to find where your Middleware Home directory is.
The environment variable is MW_HOME or ORACLE_HOME
Navigate to that directory and run startWeblogic.cmd. Then tail the out file to see if if it starts successful. From there, the process of creating a connection to the server in JDeveloper is no different than the steps listed above, except that you want to select "standalone" not "integrated".
Final Thoughts
If you want to create the Integrated Server and have already failed several times I would try the following
Stop the Integrated Server (if its running) and delete the default domain
Starting the server again (see above) will recreate the domain.
If that doesn't work delete the entire server connection and recreate. You may also want to delete the DefaultDomain folder in your %APPDATA%\JDeveloper folder
I need to shutdown port 1099 in Wildfly 10.1. This port normally used for remote JNDI/RMI and in Wildfly 10.1, the remote naming system has a
[security vulnerability][1].
The straightforward solution will be to configure a firewall to not allow traffic on 1099 port, but this is not acceptable by our client. I thought it possible to configure WF to not use remote JNDI/RMI but can't figure out how to configure it.
The JBoss documentation on Remote JNDI Interface says that you can deactivate the remote JNDI interface by executing the following command via CLI interface:
/subsystem=naming/service=remote-naming:remove
and it seems really stopping the service, but once you do server 'reload' the Wildfly resumes connection on the port 1099.
I want to check whether my JBoss EAP 7 is started via jboss-cli.
With JBoss EAP 6 I could use the following command
jboss-cli.bat -c --commands="read-attribute server-state"
While the server is starting, the response is starting. When the server booted successfully, the response is running.
After migrating to JBoss EAP 7.0, the same command returns the following message, while the server is starting. Failed to connect to the controller: Timeout waiting for the system to boot. When the server started successfully, the usual message running is returned.
My question is: Why can't the jboss-cli connect to the server until it started?
In EAP 7.x and EAP 6.3.0 or later, you can configure jboss.as.management.blocking.timeout system property to tune timeout (seconds) waiting for service container stability.
Try setting this parameter once connected via CLI.
Since EAP 6.3.0.ER8 there is a new class in jboss.as.controller: BlockingTimeout. This class loads the value of system property jboss.as.management.blocking.timeout or defaults to 300 (seconds).
Note: This property is not a timeout per deployment but a timeout on container stability and if jboss.as.management.blocking.timeout is reached during startup then all applications will be undeployed and the container shutdown. The reasoning behind this is that having a half-working server is potentially dangerous as you may not notice major failures.
Thus if your application is unable to load within the given timeout value,CLI will throw the errorFailed to connect to the controller: Timeout waiting for the system to boot
jboss-cli.sh --connect --controller=IP:PORT --timeout=40000 configure timeouts value to be more then the amount of time your server takes to start.
Actual command line is
./jboss-cli.sh --connect command=":read-attribute(name=server-state)"
