You can use scripting and the wsadmin tool to modify
WAR class loader policies for applications.
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 warClassLoaderPolicy
Example
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 warClassLoaderPolicy
Example
output:
{warClassLoaderPolicy SINGLE}
Using Jython:
AdminConfig.show(deployedObject, 'warClassLoaderPolicy')
Example
output:
'[warClassLoaderPolicy SINGLE]'
