Wie Konfiguriere ich die dynamische Weben mit EclipseLink & Frühling?

Wie kann ich konfigurieren von dynamischem weaving mit EclipseLink & Frühling? Jetzt versuche ich, diese Arbeit mit einem Junit-test, aber ich werde später haben es die Arbeit mit Tomcat (meine Abteilung wurde standardisiert auf es für so etwas wie 10 Jahre).

Ich in zwei wesentliche Probleme:

1. Frühling will ein load-time weaver:

Ausnahme:

java.lang.IllegalStateException: Failed to load ApplicationContext
at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:181)

... 44 more

Kann ich dieses Problem beheben, indem die Konfiguration der Spring Instrumentation:

JVM parameter:
-javaagent:/path/to/org.springframework.instrument-3.1.0.M2.jar

2. Eclipselink ist nicht zufrieden mit der Spring Instrumentation:

Fehler:

(similar error messages repeated many times)

Ich versucht um dies zu beheben, indem Sie mit der EclipseLink-Weber:

-javaagent:/dev/tools/javaagents/eclipselink.jar

Dann bekomme ich aber die gleiche Ausnahme von problem #1.

Library-Versionen

Ich bin mit:

  • Java 1.6.0_24
  • EclipseLink 2.2.0.v20110202-r8913
  • Spring 3.1.0 M2
