public class AnnotationProcessor6
extends javax.annotation.processing.AbstractProcessor

Annotation processing tool generates source code for a meta-model class given the annotated source code of persistent entity.

This tool is invoked during compilation for JDK6 compiler if


Usage
$ javac -classpath path/to/openjpa-all.jar -Aopenjpa.metamodel=true mypackage/MyEntity.java
will generate source code for canonical meta-model class mypackage.MyEntity_.java. The source code is generated relative to the directory specified in -s option of javac compiler and defaulted to the current directory.

The Annotation Processor also recognizes the following options (none of them are mandatory):

-Aopenjpa.log={log level}The logging level. Default is WARN. Permissible values are TRACE, INFO, WARN or ERROR.
-Aopenjpa.source={n} Java source version of the generated code. Default is 6.
-Aopenjpa.naming={class name} fully-qualified name of a class implementing org.apache.openjpa.meta.MetaDataFactory that determines the name of a meta-class given the name of the original persistent Java entity class. Defaults to org.apache.openjpa.persistence.PersistenceMetaDataFactory which appends a underscore character (_) to the original Java class name.
-Aopenjpa.header={url} A url whose content will appear as comment header to the generated file(s). Recognizes special value ASL for Apache Source License header as comment. By default adds a OpenJPA proprietary text.
