Re: [eclipselink-users] Metamodel generation of orm.xml-definied entitie

[gjanjana <gjanjana@xxxxxxxxx>]

Hey Frank,
Just wondering how you are able to get it working? I am getting following
error

"Mapping metadata cannot be applied to properties/methods that take
arguments. The attribute [method addGroup] from class [class UserGroupList]
is in violation of this restriction. Ensure the method has no arguments if
it is mapped with annotations or in an XML mapping file."

I have class userGroupList which is an entity with access type set to
"Field" not "Property", not sure why is it trying to validate methods. I do
have method addGroup in that class but it is just a business method  that
EclipseLink need not worry.

For your reference, this is how I try to generate the metadata information
using Ant:
------------------------------------------------------
  <target name="generate-metamodel" >
        <property name="metaPackage" value="metamodel"/>
        <delete>
            <fileset dir="${project.dir}/src"  includes="**/*_.java"/>
        </delete>
       <echo message="generating MetaData "/>
       <javac   srcdir="${project.dir}/src" verbose="true"
            destdir="${project.dir}/src"
            classpathref="compile.class.path">
              <compilerarg line=" -processor
org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor" />
              <compilerarg line=" -proc:only" compiler="javac1.6" />			  
        </javac>

</target>
------------------------------------------------------

I have also tried with the eclipse AnnotationProcessor but getting same
error. Any help is appreciated.
