Previously i wrote a blog post about how to detect if a JBoss instance is started.

• Linux – Wait until a specific pattern is written on log using tail and sed

 

Here comes the Twiddle solution.

1. Enable the JMXConsole user by editing the <JBoss>/server/[instance]/conf/props/jmx-console-users.properties.

# A sample users.properties file for use with the UsersRolesLoginModule
admin=admin

 

2. Go to <JBoss>/bin and run the following command.

• ./twiddle.sh -s localhost:1099 –user=admin –password=admin get jboss.system:type=Server Started

 

3. The above command assume your JBoss instance is using JBOSS_BINDING_SET=ports-default. If you have multiple JBoss instances running with different ports, you will need to alter the port number in the command. Say for ports-01.

• ./twiddle.sh -s localhost:1199 –user=admin –password=admin get jboss.system:type=Server Started

 

4. Just keep adding 100 to the port number with respect to your JBOSS_BINDING_SET setting.
 

5. If the JBoss instance has started, you will get the following output.

• Started=true

 

Done =)
