About this task
To modify WAR class loader policies for an application, perform the following steps:
Procedure
- 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 [$AdminConfig getid /Deployment:MyApp/]Using Jython
dep = AdminConfig.getid("/Deployment:MyApp/")
- Identify the deployed object and set it to the deployedObject variable. For example:
Using Jacl
set deployedObject [$AdminConfig showAttribute $dep deployedObject]Using Jython
deployedObject = AdminConfig.showAttribute(dep, "deployedObject")
- Show the current attribute values of the configuration object with the show command, for example:
Using Jacl
$AdminConfig show $deployedObject warClassLoaderPolicyExample output:
{warClassLoaderPolicy MULTIPLE}Using Jython
AdminConfig.show(deployedObject, 'warClassLoaderPolicy')Example output:
'[warClassLoaderPolicy MULTIPLE]'
- 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']])
- Verify the changes that you made to the attribute value with the show command, for example:
Using Jacl
$AdminConfig show $deployedObject warClassLoaderPolicyExample output:
{warClassLoaderPolicy SINGLE}Using Jython
AdminConfig.show(deployedObject, 'warClassLoaderPolicy')Example output:
'[warClassLoaderPolicy SINGLE]'
