View JMS bindings on references and services of SCA composites using scripting

We can view information on a Java Message Service (JMS) binding for a Service Component Architecture (SCA) composite. Use scripts for viewing composition units in business-level applications. The scripts display information on settings of a binding.jms element.

An SCA composite that uses JMS bindings must be a composition unit in a business-level application.

To view settings for a JMS binding on references, the composite must have defined a JMS binding in the reference. Similarly, to view settings for a JMS binding on services, the composite must have defined a JMS binding in the service.

After deployment of an SCA composite that uses JMS bindings, you can view the JMS binding settings. For information on the settings, refer to JMS binding settings for SCA composites or Section 1.4 of the SCA JMS Binding specification, Version 1.00.


Procedure

  1. Start wsadmin.sh.

  2. Optional: View online help for the viewCompUnit command.

    ### Jython 

    print AdminTask.help('viewCompUnit')

    ### Jacl 

    $AdminTask help viewCompUnit

  3. View all information on a composition unit, including information on any JMS binding settings.

    Use the viewCompUnit command. The command has two parameters, -blaID and -cuID, both of type String.

    ### Jython 

    AdminTask.viewCompUnit('[-blaID myBLA -cuID myCompUnit]')

    ### Jacl 

    $AdminTask viewCompUnit {-blaID myBLA -cuID myCompUnit}


Results

After the viewCompUnit command runs, the product displays information on the composition unit, including information on references or services that are defined in the JMS binding of the SCA composite.


Example

Suppose that we have an SCA composite composition unit named myJmsBindingComposite that has defined JMS bindings and a business-level application named myJmsBLA that contains the composition unit.

Run the viewCompUnit command to view information on the JMS binding settings.

Run the viewCompUnit command displays information resembling the following on the JMS binding sections:
