org.eclipse.persistence.exceptions.ValidationException - JPA ManyToMany mapping

Hello All,

I am new to Eclipse. I stuck since 3 days on strange problem. What I have done:

1. Downloaded and installed Eclipse (eclipse-jee-indigo-SR1-win32-x86_64.zip)
2. Installed GlassFish (glassfish-3.1.1-windows.exe)
3. Installed plugin for Glassfish (for Eclipse Indigio IDE)
4. Created EJB project with facets: Java,EJB,jpa 2.0
5. GlassFish target platform: "GlassFish Server Open Source(Java EE6)"
6. jpa settings - selected as Platform "EclipseLink 2.3"
7. Generated "jpa Entities form Tables"

When I am trying to deploy this application to server I receive following exception:

Exception Description: Predeployment of PersistenceUnit [MegajanServerApp] failed.
Internal Exception: Exception [EclipseLink-7333] (Eclipse Persistence Services -
2.3.0.v20110604-r9504): org.eclipse.persistence.exceptions.ValidationException
Exception Description: The reference column name [name] mapped on the element [field products] does not
correspond to a valid field on the mapping reference.. Please see server.log for more details.

Here is the mapping definition generated in one of my classe:

//bi-directional many-to-many association to Product
@ManyToMany
@JoinTable(
name="job_products"
, joinColumns={
@JoinColumn(name="job_id", nullable=false)
}
, inverseJoinColumns={
@JoinColumn(name="product_name", referencedColumnName="name", nullable=false)
}
)
private List<Product> products;

In my opinion there is no problem with mapping definition but there is a bug in EclipseLink in this
validation. I found no solution for this problem on the Web. What I tried:

1. Some people calimed this is case-sensitivity issue in mapping definition but this is not my case.
(included in persistence.xml following line <property
name="eclipselink.jpa.uppercase-column-names" value="false"/> and problem still exists)
2. Updated everything what I supposed to cause this error. Even EclipseLink 2.4.0 night build.
3. Reinstalled many times GlassFish server 3.1, Eclipse Indigio IDE
4. The strangest thing is that about 2 month ago I did the same things but on other PC machine and it worked
fine. ???

I am so disappointed... How can I design reliable, distributed applications with EJB 3.1 if mentioned bugs
occur? Maybe I will try NetBeans IDE.
Please, give me any solution to this problem.

Best regards,
Slawek
