Example: Configuring a shared library for an application

You can use the AdminApp object to set certain configurations in the application. This example uses the AdminConfig object to configure a shared library for an application.

• Identify the shared library and assign it to the library variable.

  • To create a new shared library, perform the following steps:

    1. Idenitfy the node and assign it to a variable, for example:

       Using Jacl:

       set node [$AdminConfig getid /Cell:mycell/Node:mynode/]

       Using Jython:

       node = AdminConfig.getid('/Cell:mycell/Node:mynode/')
       print node

       Example output:

       mynode(cells/mycell/nodes/mynode:node.xml#Node_1)

    2. Create the shared library in the node, for example:

       Using Jacl:

       set library [$AdminConfig create Library $node {{name mySharedLibrary} {classPath c:/mySharedLibraryClasspath}}]

       Using Jython:

       library = AdminConfig.create('Library', node, [['name', 'mySharedLibrary'], ['classPath', 'c:/mySharedLibraryClasspath']])
       print library

       Example output:

       MySharedLibrary(cells/mycell/nodes/mynode:libraries.xml#Library_1)

       This example creates a new shared library in the node scope. You can modify it to use the cell or server scope.

  • To use an existing shared library, issue the following command:

    Using Jacl:

    set library [$AdminConfig getid /Library:mySharedLibrary/]

    Using Jython:

    library = AdminConfig.getid('/Library:mySharedLibrary/')
    print library

    Example output:

    MySharedLibrary(cells/mycell/nodes/mynode:libraries.xml#Library_1)

• Identify the deployment configuration object for the application and assign it to the deployment variable:

  Using Jacl:

  set deployment [$AdminConfig getid /Deployment:myApp/]

  Using Jython:

  deployment = AdminConfig.getid('/Deployment:myApp/')
  print deployment

  Example output:

  myApp(cells/mycell/applications/myApp.ear/deployments/myApp:deployment.xml#Deployment_1)

• Retrieve the application deployment and assign it to the appDeploy variable:

  Using Jacl:

  set appDeploy [$AdminConfig showAttribute $deployment deployedObject]

  Using Jython:

  appDeploy = AdminConfig.showAttribute(deployment, 'deployedObject')
  print appDeploy

  Example output:

  (cells/mycell/applications/myApp.ear/deployments/myApp:deployment.xml#ApplicationDeployment_1)

• Identify the class loader in the application deployment and assign it to the classLoader variable:

  Using Jacl:

  set classLoader [$AdminConfig showAttribute $appDeploy classloader]

  Using Jython:

  classLoader = AdminConfig.showAttribute(appDeploy, 'classloader')
  print classLoader

  Example output:

  (cells/mycell/applications/myApp.ear/deployments/myApp:deployment.xml#Classloader_1)

• Associate the shared library in the application through the class loader:

  Using Jacl:

  $AdminConfig create LibraryRef $classLoader {{libraryName MyshareLibrary} {sharedClassloader true}}

  Using Jython:

  print AdminConfig.create('LibraryRef', classLoader, [['libraryName', 'MyshareLibrary'],  ['sharedClassloader', 'true']])

  Example output:

  (cells/mycell/applications/myApp.ear/deployments/myApp:deployment.xml#LibraryRef_1)

• Save the changes:

  Using Jacl:

  $AdminConfig save

  Using Jython:

  AdminConfig.save()
