Disabling Weaving with Persistence Unit Properties

To disable weaving using EclipseLink persistence unit properties:

1. Configure your persistence.xml file with one or more of the following properties set to false:
   • eclipselink.weaving – disables all weaving;
   • eclipselink.weaving.lazy – disables weaving for lazy loading (indirection);
   • eclipselink.weaving.changetracking – disables weaving for change tracking;
   • eclipselink.weaving.fetchgroups – disables weaving for fetch groups.
   • eclipselink.weaving.internal – disables weaving for internal optimization.
   • eclipselink.weaving.eager – disables weaving for indirection on eager relationships.
     
     
   This example shows how to disable weaving for change tracking only.
   Disabling Weaving for Change Tracking in the persistence.xml File

   <persistence>
       <persistence-unit name="HumanResources">
           <class>com.acme.Employee</class>
   
           ...
           <properties>
               <property
                   name="eclipselink.weaving.changetracking"
                   value="false"
               />
           </properties>
       </persistence-unit>
   </persistence>
   

   The following example shows how to disable all weaving: in this example, EclipseLink does not weave for lazy loading (indirection), change tracking, or internal optimization.

   Disabling All Weaving in the persistence.xml File

   <persistence>
       <persistence-unit name="HumanResources">
           <class>com.acme.Employee</class>
   
           ...
           <properties>
               <property
                   name="eclipselink.weaving"
                   value="false"
               />
           </properties>
       </persistence-unit>
   </persistence>
   

2. Package and and deploy your application. .
