Enable JPA 2.0 on Weblogic Server Support for JPA 2.0 in WebLogic Server is provided as a patch, because JPA 2.0 is part of Java Platform, Enterprise Edition (Java EE) 6. Therefore, enabling JPA 2.0 support in the current release results in WebLogic Server not meeting all Java EE 5 compatibility requirements. To maintain Java EE 5 compatibility in the current release, the files required for the support are not enabled by default, although they are included in a standard WebLogic Server installation. Install the Patch - Using Smart Update To install the patch using Smart Update, do the following: Ensure that you are logged in to My Oracle Support. For information, see  http:\\support.oracle.com . Start Smart Update, as described in " Starting Smart Update ." In the  Target Installation  panel of the main Smart Update window, select the target installation. Select the  Get Patches  tab. In the available patches panel, select the check box for patch  QWG8 - Enab
