You can use a WebLogic Administration Server browser from which you can select the data source or transaction data source and its relevant settings. The Administration Server browser provides an alphabetical list of applications on the Administration Server.
The WebLogic plug-in also includes a default data source and transaction data source, which eliminates the need for browsing. You can find the default components in the /com/sun/webLogic8 folder or by selecting View All from the Common Tasks page. The default components can then be installed through the component Details page using the Default: Install component procedure. The default components are named as follows:
WLDataSourceConfig – the data source component
WLTxDataSourceConfig – the transactional data source component
