Working with library reference properties files

You can use properties files to create or change library reference properties under a PARENT_LAST class loader that is under the ApplicationServer object of a server.

Before you begin

Determine the changes that you want to make to your library reference configuration or its configuration objects.

Start the wsadmin scripting tool. To start wsadmin using the Jython language, run the wsadmin -lang Jython command from the bin directory of the server profile.

About this task

Using a properties file, you can create, modify, or delete a library reference object and its configuration properties.

Run administrative commands using wsadmin to create or change library reference properties, validate the properties, and apply them to your configuration.

Table 1. Actions for library reference properties files . You can create, modify, and delete library reference configuration properties.
Action	Procedure
create	Set properties and then run the applyConfigProperties command.
modify	Edit properties and then run the applyConfigProperties command.
delete	Uncomment `#DELETE=true` and run the deleteConfigProperties command.
create Property	Not applicable
delete Property	Not applicable

Optionally, you can use interactive mode with the commands:

AdminTask.command_name('-interactive')

Procedure

Create a library reference and its properties.
1. Create LibraryRef properties.
  Open an editor and specify library reference properties. You can copy the following example properties into an editor and modify the properties as needed for your situation. The example defines a library reference under a PARENT_LAST class loader that is under the ApplicationServer object of a server.
```
#
# SubSection 1.0.0.0.0 # ApplicationServer Classloader
#
ResourceType=LibraryRef
ImplementingResourceType=GenericType
ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:ApplicationServer=:
Classloader=mode#PARENT_LAST:LibraryRef=libraryName#mylibName
AttributeInfo=libraries
#DELETE=true


#
#Properties
#
libraryName=mylibName
sharedClassloader=false #boolean,default(true)
```
2. Run the applyConfigProperties command to create a library reference configuration.
  Running the applyConfigProperties command applies the properties file to the configuration. In this Jython example, the optional -reportFileName parameter produces a report named report.txt:
```
AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt '])
```
Modify an existing library reference.
1. Obtain a properties file for the library reference that you want to change.
  You can extract a properties file for a LibraryRef object using the extractConfigProperties command.
2. Open the properties file in an editor and change the properties as needed.
  Ensure that the environment variables in the properties file match your system.
3. Run the applyConfigProperties command.
If you no longer need a library reference, you can delete the entire library reference object.
To delete the entire object, specify DELETE=true in the header section of the properties file and run the deleteConfigProperties command; for example:
```
AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]') 
```

Results

You can use the properties file to configure and manage the library reference properties.

What to do next

Save the changes to your configuration.
