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 – can be used to disables all weaving;
    • eclipselink.weaving.lazy – can be used to disables weaving for lazy loading (indirection);
    • eclipselink.weaving.changetracking – can be used to disables weaving for change tracking;
    • eclipselink.weaving.fetchgroups – can be used to disables weaving for fetch groups.
    • eclipselink.weaving.internal – can be used to disables weaving for internal optimization.
    • eclipselink.weaving.eager – can be used to enables weaving for indirection on eager relationships, this allows change tracking on eager collection relationships, and improves cache concurrency for eager object 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. .
