Customization

Weaving

Specifies if weaving of the entity classes is performed. The EclipseLink JPA persistence provider uses weaving to enhance JPA entities for such properties as lazy loading, change tracking, fetch groups, and internal optimizations. Select from the following options:

• No Weaving

• Weave Dynamically

• Weave Statically -- Use this option if you plan to execute your application outside of a Java EE 5 container in an environment that does not permit the use of -javaagent:eclipselink.jar on the JVM command line. This assumes that classes have already been statically woven. Run the static weaver on the classes before deploying them.

Weave Dynamically

Lazy

Select this option to enable lazy weaving.

True

Fetch Groups

Select this option to enable fetch groups through weaving. Set this option to false if:

• There is no weaving.

• Classes should not be changed during weaving (for example, when debugging).

Set this property to false for platforms where it is not supported.

True

Internal

Specify if Dali uses internal optimizations through weaving.

If enabled, enables lazy one-to-one and many-to-one mappings through weaving.

True

Eager

Specify if Dali uses indirection on eager relationships.

False

Change Tracking

Select this option to use weaving to detect which fields or properties of the object change.

True

Validation only

Specify if Dali should validate deployments by initializing descriptors but not connecting to the data source.

True

Mapping files schema validation

False

Throw exceptions

Select this option to set EclipseLink to throw an exception or log a warning when it encounters a problem with any of the files listed in a persistence.xml file <mapping-file> element.

True

Exception handler

Select (or create) a Java class (that implements the org.eclipse.persistence.exceptions.ExceptionHandler interface) to handle exceptions.

Session Customizer

Select a session customizer class: a Java class that implements the eclipselink.tools.sessionconfiguration.SessionCustomizer interface and provides a default (zero-argument) constructor. Use this class' customize method, which takes an eclipselink.sessions.Session, to programmatically access advanced EclipseLink session API.

Profiler

Specify which performance profiler to use in order to capture runtime statistics.

• No Profiler – Do not use a performance profiler.

• Performance Profiler – Use EclipseLink performance profiler (org.eclipse.persistence.tools.profiler.PerformanceProfiler class).

• Query Monitor – Monitor query executions and cache hits (org.eclipse.persistence.tools.profiler.QueryMonitor class).
