Add Server Instance Wizard: Oracle WebLogic Server Instance Properties

You see this page of the Add Server Instance wizard when you are registering an Oracle WebLogic Server instance.

Use this page to specify the properties of the instance that you are registering.

Domain. Select the location of the domain that you want to associate with the server instance. The IDE will automatically populate this field if the server instance that you selected is already configured to use a specific domain. Use the Browse button to locate a different domain for the server instance.
Username. Type the username.
Password. Type the password.
JPA 2 Support. Click to enable or disable JPA 2 support on the server.
This option is not available for Oracle WebLogic Server 12c and newer because JPA 2 support is enabled by default.

Notes.

The default username/password for the Oracle WebLogic Server is weblogic/weblogic.
On some older versions of Oracle WebLogic Server you need to explicitly enable support for JPA 2. The files for supporting JPA 2 are included with the WebLogic Server installation but are disabled by default. When you enable JPA 2 in the wizard, the IDE modifies the WebLogic Server classpath to add the required files to the start of the classpath.
You can enable or disable support for JPA 2 on the WebLogic Server at any time in the WebLogic Server panel of the Servers manager. You can open the Servers manager by choosing Tools > Servers from the main menu or by right-clicking a server instance node in the Services window and choosing Properties.
