Description

1. Use service discovery mechanism to invoke annotation processor for metamodel generation
2. Provide a activation switch -Aopenjpa.generate=true such that the user must enable the switch to generate these metamodel classes besides having openjpa.jar in classpath.

Target usage patterns

A. Using command lines

$ javac -cp /path/to/openjpa.jar -Aopenjpa.generate=true src/org/acme/Foo.java

B. Using Eclipse IDE
In 'Configure Annotation Processor Dialog'
– set openjpa.generate to 'true'
– include openjpa jar in factory path

C. Using Ant
<javac .....
<classpath refid="openjpa.jar"/>
<compilerarg value="-Aopenjpa.generate=true"/>
</javac>
