Installing Manually

The files required for supporting JPA 2.0 are included with a default WebLogic Server installation, but they are not enabled by default. The files are installed in the WL_HOME\modules directory. The files are:

• The javax.persistence_1.0.0.0_2-0-0 JAR file contains the JPA 2.0 libraries.

• The com.oracle.jpa2support_1.0.0.0_2-0.jar file contains the files for enabling JPA 2.0 support in WebLogic Server.

If you do not have an active My Oracle Support account (which you need to use Smart Update) you can install the patch manually by putting the files at the start of the WebLogic classpath. For example, you can use either of the following ways:

• Define a PRE_CLASSPATH environment variable before starting WebLogic Server.

  For example, in a Windows console window, run the following script before running startWebLogic.cmd:

  @echo off
  if ".%1" == "." goto TellSyntax
  set wls_modules=%1
  set PRE_CLASSPATH=%wls_modules%\javax.persistence_1.0.0.0_2-0-0.jar;
  %wls_modules%\com.oracle.jpa2support_1.0.0.0_2-0.jar
  goto End
  :TellSyntax
  echo setJPA2SupportPatch [path-to-weblogic-modules-directory
  :End
  echo PRE_CLASSPATH=%PRE_CLASSPATH%
  

  A similar script can be written for Linux, UNIX, or Macintosh.

• Modify the commEnv.cmd or commEnv.sh script in the WL_HOME/common/bin directory, and define the PRE_CLASSPATH at the beginning of the script. 

My example at win7 will be modifying commEnv.cmd to add the below statement

@ enale JPA2.0 for weblogic 10.3.6
set PRE_CLASSPATH=%MODULES_DIR%\org.eclipse.persistence_1.2.0.0_2-3.jar;%MODULES_DIR%\javax.persistence_1.1.0.0_2-0.jar

another way is editing  setDomainEnv.cmd  and adding  javax.persistence_1.0.0.0_2-0-0.jar  and  com.oracle.jpa2support_1.0.0.0_2-0.jar  to the  PRE_CLASSPATH  environment variable as below shown.

REM Add JARs for JPA 2.0 at the front of the class path.
set WLS_MODULES=%WL_HOME%\..\modules
set PRE_CLASSPATH=%WLS_MODULES%\javax.persistence_1.0.0.0_2-0-0.jar;%WLS_MODULES%\com.oracle.jpa2support_1.0.0.0_2-0.jar
