spring eclipselink problem with IntegrityException - spring

Question

I try to use spring with eclipseLink and I've got an IntegrityException.
This is my configuration:

<!-- </bean> -->
</property>
</bean>
<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
and exactly exception is:

but i don't have this problem when I use another Vendor
org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter
any ideas?

Answer 1

Try to use this loadtimeweaver implementation:
package net.palesz.util;
import org.springframework.instrument.classloading.SimpleLoadTimeWeaver;
public class JpaAwareLoadTimeWeaver extends SimpleLoadTimeWeaver {
#Override
public ClassLoader getInstrumentableClassLoader() {
ClassLoader instrumentableClassLoader = super.getInstrumentableClassLoader();
if (instrumentableClassLoader.getClass().getName().endsWith("SimpleInstrumentableClassLoader")) {
return instrumentableClassLoader.getParent();
} else {
return instrumentableClassLoader;
}
}
}
Spring context.xml config:
<bean id="loadTimeWeaver" class="net.palesz.util.JpaAwareLoadTimeWeaver" />

Answer 2

An odd error because IndirectSet is valid. It seems to be a class loader issue, but I have not seen this in Spring before.
It could be related to your usage of loadTimeWeaver, so you could try removing that.
In what environment are you running Spring?

Answer 3

you have to use agent for dynamic weaving
-javaagent:spring-agent-2.5.6.jar
i had tried eclipseLink agent, but it didn't work.
more info about weaving for JPA on Spring:
http://docs.spring.io/spring/docs/3.0.0.M3/reference/html/ch14s06.html
if you would like run your code on tomcat:
