Dynamic Weaving

Use this option to weave applicable class files one at a time, as they are loaded at run time.

Use this option to weave applicable class files one at a time, as they are loaded at run time. Consider this option when the number of classes to weave is few or the time taken to weave the classes is short.

If the number of classes to weave is large or the time required to weave the classes is long, consider using static weaving. For more information, see How to Configure Static Weaving for JPA Entities.


To Configure Dynamic Weaving for JPA Entities Using the EclipseLink Agent

  1. Modify your application JVM command line to include the following:

    -javaagent:eclipselink.jar

  2. Ensure that the eclipselink.jar is in your application classpath.
  3. Package and deploy your application.
    For more information, see Packaging an EclipseLink JPA Application.

EclipseLink weaves applicable class files one at a time, as they are loaded at run time.
