Re: [eclipselink-users] Weaving in Spring problem

[Gaurav Malhotra <gaurav.malhotra@xxxxxxxxxx>]

Modify your test run configuration and pass the spring agent as argument
shown below

Note:- Eclipselink does loading time weaving (using ASM) and for it requires
the weaver. All jee compliant app server have the weaver. But while
launching in eclipse or other ide its mandatory to specify the weaver.

-javaagent:path to spring
framework\spring-framework-2.5.5\dist\weaving\spring-agent.jar

Observation :- You must use Shared entity manager and spring java support to
ease your coding
