Set new J2C activation specifications using scripting

Configure new J2C activation specifications using scripting and wsadmin.

Before starting this task, wsadmin must be running. See the Start wsadmin article for more information.

Perform the following steps to configure a J2C activation specifications:

 

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

   • Jacl...

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

   • Jython...

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

   For example...

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

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

   • Use AdminTask:

     1. List the admin object interfaces:

        Jacl...

        $AdminTask listMessageListenerTypes $newra

        Jython...

        AdminTask.listMessageListenerTypes(newra)

        Example output:

        javax.jms.MessageListener

     2. Create a J2C admin object:

        Jacl...

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

        Jython...

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

   • Use the AdminConfig object:
     1. Jacl...

        $AdminConfig required J2CActivationSpec

        Jython...

        print AdminConfig.required('J2CActivationSpec')

        Example output:

        Attribute Type activationSpec ActivationSpec@

     2. If the resource adapter is JCA V1.5 and we have multiple activation specifications defined, it is required that specify the activation specification attribute. If the resource adapter is JCA V1.5 and we have only one activation specification defined, it will be picked up automatically. If the resource adapter is JCA V1.0, you do not need to specify the activationSpec attribute. Perform the following command to list the activation specifications defined by the resource adapter:

        Jacl...

        $AdminConfig list ActivationSpec $newra

        Jython...

        print AdminConfig.list('ActivationSpec', $newra)

     3. Set the admin object that we need to a variable:

        Jacl...

        set ac [$AdminConfig list ActivationSpec $newra] set name [list name J2CAC1] set jname [list jndiName eis/J2CAC1] set j2cacAttrs [list $name $jname $cdcttr]

        Jython...

        ac = AdminConfig.list('ActivationSpec', $newra) name = ['name', 'J2CAC1'] jname = ['jndiName', 'eis/j2cac1'] j2cacAttrs = [name, jname,cdattr]

     4. If specifying the ActivationSpec attribute, also set up the following:Using Jacl:

        set cdcttr [list activationSpec $ac]

        Jython...

        cdattr = ['activationSpec', ac]

     5. Create a J2C activation spec object:

        Jacl...

        $AdminConfig create J2CActivationSpec $newra $j2cacAttrs

        Jython...

        print AdminConfig.create('J2CActivationSpec', newra,j2cacAttrs)

        Example output:

        J2CAC1(cells/mycell/nodes/mynode|resources.xml#J2CActivationSpec_1)

3. Save the configuration changes. See the Saving configuration changes with wsadmin article for more information.

4. In a network deployment environment only, synchronize the node. See the Synchronizing nodes with wsadmin article for more information.
