hello all,

Please help me in this. I am getting a warning while running the maven project.
The warning is like this: [EL Info]: 2014-09-05 14:39:29.444--ServerSession(2111097532)--EclipseLink, version: Eclipse Persistence Services - 2.4.0.v20120608-r11652
[EL Warning]: metadata: 2014-09-05 14:39:29.484--ServerSession(2111097532)--Reverting the lazy setting on the OneToOne or ManyToOne attribute [gdutypeId] for the entity class [class com.model.Gdu] since weaving was not enabled or did not occur.

In pom.xml, I have added the plugins and in persistence.xml , I have already added <property name="eclipselink.weaving" value="static"/>. Still it is giving error. Please help me in this.
