Configure new J2C activation specs using scripting

Before starting this task, the wsadmin tool must be running. See the Starting the wsadmin scripting client article for more information.

Perform the following steps to configure a J2C activation specs:

Identify the parent ID and assign it to the newra variable.

Using Jacl:

set newra [$AdminConfig getid /Cell:mycell/Node:mynode/J2CResourceAdapter:RAR1/]

Using Jython:

newra = AdminConfig.getid('/Cell:mycell/Node:mynode/J2CResourceAdapter:RAR1/')
print newra

Example output:

RAR1(cells/mycell/nodes/mynode|resources.xml#J2CResourceAdapter_1)

There are two ways to configure a new J2C administrative object. Perform one of the following:

Using the AdminTask object:

List the administrative object interfaces:Using Jacl:

$AdminTask listMessageListenerTypes $newra

Using Jython:

AdminTask.listMessageListenerTypes(newra)

Example output:

javax.jms.MessageListener

Create a J2C administrative object:Using Jacl:

$AdminTask createJ2CActivationSpec $newra { -name ac1 -jndiName eis/ac1 -message ListenerType javax.jms.MessageListener}

Using Jython:

AdminTask.createJ2CActivationSpec(newra, ['-name', 'ao1', '-jndiName', 'eis/ao1', '-message', 'ListenerType', 'javax.jms.MessageListener'])

Using the AdminConfig object:
1. Using Jacl:
```
$AdminConfig required J2CActivationSpec
```
  Using Jython:
```
print AdminConfig.required('J2CActivationSpec')
```
  Example output:
```
Attribute Type activationSpec ActivationSpec@
```
2. If your resource adapter is JCA V1.5 and you have multiple activation specs defined, it is required that you specify the activation spec attribute. If your resource adapter is JCA V1.5 and you have only one activation spec defined, it will be picked up automatically. If your resource adapter is JCA V1.0, you do not need to specify the activationSpec attribute. Perform the following command to list the activation specs defined by the resource adapter:Using Jacl:
```
$AdminConfig list ActivationSpec $newra
```
  Using Jython:
```
print AdminConfig.list('ActivationSpec', $newra)
```
3. Set the administrative object that you need to a variable:Using Jacl:
```
set ac ActivationSpecID
set name [list name J2CAC1]
set jname [jndiName eis/j2cac1]
set j2cacAttrs [list $name $jname]
```
  Using Jython:
```
ac = ActivationSpecID 
name = ['name', 'J2CAC1']
jname = ['jndiName', 'eis/j2cac1']
j2cacAttrs = [name, jname]
```
4. If you are specifying the ActivationSpec attribute, also set up the following:Using Jacl:
```
set cdcttr [list activationSpec $ac]
```
  Using Jython:
```
cdattr = ['activationSpec', ac]
```
5. Create a J2C activation spec object:Using Jacl:
```
$AdminConfig create J2CActivationSpec $newra $j2cacAttrs
```
  Using Jython:
```
print AdminConfig.create('J2CActivationSpec', newra,j2cacAttrs)
```
  Example output:
```
J2CAC1(cells/mycell/nodes/mynode|resources.xml#J2CActivationSpec_1)
```

Save the configuration changes. See the Saving configuration changes with the wsadmin tool article for more information.
In a network deployment environment only, synchronize the node. See the Synchronizing nodes with the wsadmin tool article for more information.
