> 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"/>
