Thanks that works. By changing the meta tag 

from:

<meta attribute="implements">com.rhi.domain.Person</meta>

to:

<meta inherit="false" attribute="implements">com.rhi.domain.Person</meta> 

The interface gets only implemented by the class indicated in the class tag.

I personally think this feature of inherting the meta tag is not very intuitive. I don't think very often one wants all its classes to implement the same interface or pass another meta attribute to all its classes and methods. I think it would be more intuitive if the meta tag is applied to only the tags which it is a direct child of.

        Key: HB-242
    Summary: <meta attribute="implements"> does not behave as expected
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate2
 Components: 
             toolset
   Versions:
             2.0.1

Environment: JDK1.4

Description:
If the tag <meta attribute="implements">com.hp.Printer</meta> is inserted as a child of the class tag it properly adds the implement clause to the class. But if that class also contained a <composite-id> tag which indicated a class then that class would also UNEXPECTEDLY implement the interface "com.hp.Printer".


So in the following example:

<class name="com.hp.ColorPrinter">
<meta attribute="implements">com.hp.Printer</meta> 
<composite-id
        name="propertyName"
        class="com.hp.PrinterId">

        <key-property name="propertyName" type="typename" column="column_name"/>
        <key-many-to-one name="propertyName class="ClassName" column="column_name"/>
</composite-id>

Both "ColorPrinter" and "PrinterId" end up implementing "com.hp.Printer". ColorPrinter is expected to implement the interface, but PrinterId should not implement the interface.
