Hi.. When my application starts, Eclipselink loggs this warnings:

[2013-01-23 18:34:00.979] INFO  http-bio-8080-exec-10        System.out                                                        [EL Warning]: metadata: 2013-01-23 18:34:00.979--ServerSession(1512579774)--Reverting the lazy setting on the OneToOne or ManyToOne attribute [usina] for the entity class [class br.com.autmix.domain.traco.TracoFamilia] since weaving was not enabled or did not occur.

For various entities

In my persistence.xml weaving is enabled:

<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
	
	<exclude-unlisted-classes>false</exclude-unlisted-classes>
	<properties>
			<!-- Fazer waving das classes -->
			<property name="eclipselink.weaving" value="true"/>
			
			<property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
			<property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/autmix_2" />
			<property name="javax.persistence.jdbc.user" value="postgres" />
			<property name="javax.persistence.jdbc.password" value="postgres" />
			
			<property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.PostgreSQLPlatform" />
			<property name="eclipselink.jdbc.connection_pool.default.initial" value="2" />
			<property name="eclipselink.jdbc.connection_pool.default.min" value="2" />
			<property name="eclipselink.jdbc.connection_pool.default.max" value="5" />

			<!-- Geracao de DDL -->
			<property name="eclipselink.ddl-generation" value="none" />
			
			<!-- Log Configs gerais -->
			<property name="eclipselink.logging.logger" value="ServerLogger"/>
			
			<!-- Log config (Warns) -->
			<property name="eclipselink.logging.level" value="WARNING"/>
			<property name="eclipselink.logging.parameters" value="true"/>

This is the normal behavior for this kind of config?

Weaving is required to allow lazy loading of OneToOne and ManyToOne relationships, otherwise the relationship must be eagerly fetched as the warning states. Weaving is described here:
http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Advanced_JPA_Development/Performance/Weaving

Dynamic weaving requires the use of a java agent in java SE, but is automatic with container managed persistence units. If you cannot use dynamic weaving, static weaving allows the classes to be modified prior to deployment.

I used this to enable static weaving for my SDK application.

It's SDK.

Im using OSGi, on Eclipse Virgo and Gemini JPA, but its not an EE Container.

No problem in use static weaving, but, can I automate the weaving on eclipse, to deploy alread woven classes when developing?

I have it auto-enabled on NetBeans, maybe this will help:

<target name="[b]-post-jar[/b]" description="perform weaving">
        <taskdef name="weave" classname="org.eclipse.persistence.tools.weaving.jpa.StaticWeaveAntTask"/>
        <weave 
            source="C:\Users\Minutis\Documents\NetBeansProjects\PUMinutis\dist\PUMinutisUnweaven.jar" <!-- default NetBeans jar -->
            target="C:\Users\Minutis\Documents\NetBeansProjects\PUMinutis\dist\PUMinutis.jar" <!-- my weaven jar -->
        />
    </target>

You can override '-post-jar' target and NetBeans will automaticly do this at compile time.
