Other Useful Shell Tricks

The shell can be used to launch user interfaces (UIs) associated with Services or Mbeans. Here is an example of launching a UI associated with the Install Services' Mbean. The UI is launched by navigating to the appropriate place in the Openwings hierarchy and typing its name.

Openwings@root\> ls PLATFORMS:   pc-myhost-100.100.100.10 Openwings@root\> cd pc-myhost-100.100.100.10 Openwings@...\pc-myhost-100.100.100.10> ls SERVICES:   ... MBEANS:   ... COMPONENTS:   ... PROCESSES:   installer-c9a86136_9d2f42a7_a19f8fea_0487fea3   jakarta-tomcat-3.2.1-fa2a3ac3_10774673_abfcb7a8_91c57bb7   jini-1.1-61fad223_09c84c95_88f3db66_dd0a3813 Openwings@...\pc-myhost-100.100.100.10> cd installer-c9a8

You needn't bother typing the whole name of the process you wish to navigate to. If the name of the process is unique, the first few characters is all the shell needs to figure out what you mean. This command-completion feature works everywhere in the hierarchy.

Now we will navigate to the Logging MBean underneath the installer process in the hierarchy.

Openwings@...\installer-c9a86136_9d2f42a7_a19f8fea_0487fea3\> ls SERVICES:   net.openwings.install.Installer   net.openwings.management.RemoteManager MBEANS:   com.gd.openwings.utilities.logging.LogMBean   net.openwings.component.utilities.ComponentMBean Openwings@...> cd com.gd.openwings.utilities.logging.LogMBean Openwings@...\com.gd.openwings.utilities.logging.LogMBean\> ls com.gd.openwings.utilities.logging.LogMBean contains UIs:   com.gd.openwings.utilities.logging.LogMBeanFrameFactory Openwings@...> com.gd.openwings.utilities.logging.LogMBeanFrameFactory

The UI is started by typing its name. Here is the LoggingMBeanUI that appears:

You can also launch service UIs from the shell. The Image Service has a user interface that you can launch from the shell as follows.

The UI is started by typing its name. Here is the Image Service UI.
