Yang ZHONG commented on TUSCANY-1110:
-------------------------------------

We probably can add this into ClassImpl/DataTypeImpl:

    static Map<String,Collection<Type>> class2Types;
    public void setInstanceClassName(String instanceClassName)
    {
        super.setInstanceClassName( instanceClassName);
        class2Types.get( instanceClassName).add( this);
    }

and implement TypeHelperImpl#getType(Class c) similar to:

    class2Types.get( c.getName()).iterator().next()

Things to consider (including your approach):
    scope/HelperContext
    what else?

> In the SDO databinding for SCA, we need to introspect a java class/interface
