Why do I get this compilation warning in Netbeans?
jakarta-ee, java, java-7, netbeans
Solution
It seems (I think) that the eclipseLink annotation processing for JPA is up-to-date until Java 6. You could make a Java 6 library with the JPA sources, and only there use eclipseLink annotation processing. Having a library never hurts, and later you may upgrade to Java 7 independantly.
Can't image using much Java 7 functionality in the JPA sources.
Problem
I am working on a Java-EE project involving Glassfish 3.1.2.2 and the client component is running with Java 7 Update 21. The Swing-based client was formerly based on Java 6 Update 38 until we decided to migrate to the new Java 7 Update 21. I get the following compilation warning in Netbeans 7.3: ``` warning: Supported source version 'RELEASE_6' from annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' less than -source '1.7' ``` At this point, the compilation process hangs for about 1 minute. Btw, we still have the javaee-api-6.0.jar referenced that is provided by the Netbeans platform (I think there's no javaee-api-7.0.jar available yet?) Does somebody know the reason for this warning and how I can get rid of it ? Any help highly appreciated - many thanks in advance.
