Как настроить динамическое плетение с помощью EclipseLink & Spring? Прямо сейчас я пытаюсь заставить это работать с тестом Junit, но позже мне нужно будет заставить его работать с Tomcat (мой отдел стандартизировался на нем около 10 лет).
У меня две основные проблемы:
1. Spring хочет ткача времени:
Исключение:
java.lang.IllegalStateException: Failed to load ApplicationContext

Я могу это исправить, настроив Spring Instrumentation:
JVM parameter:
-javaagent:/path/to/org.springframework.instrument-3.1.0.M2.jar
2. Eclipselink не удовлетворен Spring Instrumentation:
Ошибка:
(similar error messages repeated many times)

Я пытался исправить это с помощью ткача EclipseLink:
-javaagent:/dev/tools/javaagents/eclipselink.jar
Но тогда я получаю то же исключение из задачи № 1.
Библиотечные версии
Я использую:
- Java 1.6.0_24
- EclipseLink 2.2.0.v20110202-r8913
