I'm running in maven 2 and attempting to build with EclipseLink 2.1. I've upgraded my GlassFish server to use EclipseLink 2.1 by following these instructions:

http:// blogs.sun.com/GlassFishPersistence/entry/updating_eclipselin k_bundles_in_glassfish

I've modified my pom.xml file per the instructions that I've managed to locate.

http:// blog.gueck.com/2009/12/generating-jpa-20-criteria-canonical. html

Everything appears to build, meaning the source files get generated but the compilation fails with the following error:

Can anyone see a reason as to why I am unable to compile successfully?

Thanks very much for the help....

I resolved my problem. The issue was the version of EclipseLink that I had specified in my pom.xml. Version 2.0.1 has an issue with the meta-model generation and, in fact, I wanted to be using version 2.1.1. Once I changed to 2.1.1 everything compiled correctly.

Just make certain that you include the correct EclipseLink repository.


        <repository>
            <id>EclipseLink Repo</id>
            <name>EclipseLink Repository for the JPA implementation</name>
            <url>http://www.eclipse.org/downloads/download.php?r=1&amp;nf=1&amp;file=/rt/eclipselink/maven.repo</url>
        </repository>
