Modifying class loader modes for applications using scripting

Before you begin

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

Why and when to perform this task

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

Steps for this task

  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 [$AdminConfig getid /Deployment:ivtApp/]
    • Using Jython:
      dep = AdminConfig.getid('/Deployment:ivtApp/')
  2. Identify the deployed object and set it to the depObject variable. For example:
    • Using Jacl:
      set depObject [$AdminConfig showAttribute $dep deployedObject]
    • Using Jython:
      depObject = AdminConfig.showAttribute(dep, 'deployedObject')
  3. Identify the class loader and set it to the classldr variable. For example:
    • Using Jacl:
      set classldr [$AdminConfig showAttribute $depObject classloader]
    • Using Jython:
      classldr = AdminConfig.showAttribute(depObject, 'classloader')
  4. Show the current attribute values of the configuration object with the showall command, for example:
    • Using Jacl:
      $AdminConfig showall $classldr
      Example output:
      {libraries {}} {mode PARENT_FIRST}
    • Using Jython:
      print AdminConfig.showall(classldr)
      Example output:
      [libraries []] [mode PARENT_FIRST]
      
  5. Modify the attributes of the configuration object with the modify command, for example:
    • Using Jacl:
      $AdminConfig modify $classldr {{mode PARENT_LAST}}
    • Using Jython:
      AdminConfig.modify(classldr, [['mode', 'PARENT_LAST']])
  6. Verify the changes that you made to the attribute value with the showall command, for example:
    • Using Jacl:
      $AdminConfig showall $classldr
      Example output:
      {libraries {}} {mode PARENT_LAST}
    • Using Jython:
      AdminConfig.showall(classldr)
      Example output:
      [libraries []] [mode PARENT_LAST]
