About this task

To modify WAR class loader policies for an application, perform the following steps:

 

Procedure

  1. Retrieve the configuration ID of the object that you want to modify and set it to the dep variable. For example:

    • Using Jacl

      set dep [$AdminConfig getid /Deployment:MyApp/]
      

    • Using Jython

      dep = AdminConfig.getid("/Deployment:MyApp/")
      
      

  2. Identify the deployed object and set it to the deployedObject variable. For example:

    • Using Jacl

      set deployedObject [$AdminConfig showAttribute $dep deployedObject]
      

    • Using Jython

      deployedObject = AdminConfig.showAttribute(dep, "deployedObject")
      

  3. Show the current attribute values of the configuration object with the show command, for example:

    • Using Jacl

      $AdminConfig show $deployedObject warClassLoaderPolicy
      

      Example output:

      {warClassLoaderPolicy MULTIPLE}
      

    • Using Jython

      AdminConfig.show(deployedObject, 'warClassLoaderPolicy')
      

      Example output:

      '[warClassLoaderPolicy MULTIPLE]'
      

  4. Modify the attributes of the configuration object with the modify command, for example:

    • Using Jacl

      $AdminConfig modify $deployedObject {{warClassLoaderPolicy SINGLE}}
      

    • Using Jython

      AdminConfig.modify(deployedObject, [['warClassLoaderPolicy', 'SINGLE']])
      

  5. Verify the changes that you made to the attribute value with the show command, for example:

    • Using Jacl

      $AdminConfig show $deployedObject warClassLoaderPolicy
      

      Example output:

      {warClassLoaderPolicy SINGLE}
      

    • Using Jython

      AdminConfig.show(deployedObject, 'warClassLoaderPolicy')
      

      Example output:

      '[warClassLoaderPolicy SINGLE]'
