Viewing JMS bindings on references and services of SCA composites using scripting (deprecated)

You 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.

Before you begin

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.

About this task

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

Start the wsadmin scripting tool.
Optional: View online help for the viewCompUnit command.
Using Jython:
```
print AdminTask.help('viewCompUnit')
```
Using Jacl:
```
$AdminTask help viewCompUnit
```

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.

Using Jython:

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

Using Jacl:

$AdminTask viewCompUnit {-blaID myBLA -cuID myCompUnit}

Table 1. viewCompUnit command elements . Run the viewCompUnit command with its two required parameters.
Variable	Description
`$`	is a Jacl operator for substituting a variable name with its value
`AdminTask`	is an object to run administrative commands with the wsadmin tool
`viewCompUnit`	is an AdminTask command
`myBLA`	is the configuration ID of the SCA business-level application
`myCompUnit`	is the configuration ID of the SCA composite composition unit

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 you 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.

Using Jython:

AdminTask.viewCompUnit('[-blaID WebSphere:blaname=myJmsBLA -cuID WebSphere:cuname=myJmsBindingComposite]')

Using Jacl:

$AdminTask viewCompUnit {-blaID WebSphere:blaname=myJmsBLA -cuID WebSphere:cuname=myJmsBindingComposite}

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

What to do next

Examine the displayed information to ensure that the JMS binding settings are correct.

Edit the JMS binding resource and response resource JNDI name settings as needed using the editCompUnit command.
