I'm not quite following, but I would say, that expected way of creating 
a tool which puts Java code into MDR is :

1.) create metamodel of Java language, go to the complexity you need ( 
actually XMI of metamodel )
    This step can be done in various way :
       a.) use Java metamodel already present in Netbeans, it is quite 
complex and covers "almost all features" of current Java.
       b.) find some other metamodel anywhere
       c.) create a metamodel of your own : create an UML model, then 
use uml2mof tool to convert it to metamodel

2.) import "Java metamodel XMI" into MDR repository, generate Java 
interfaces for it

    2.5 ) optional : customize metamodel by implementing "derived" MOF 
associations, or "additional" interface methods in metamodel

3.) write a tool which
        a.) parses java code from *.java files ( or loads informations 
from *.class files )
        b.) puts this information into Java metamodel you are using ( 
from the step 1. ) by "calling/using interfaces/methods" created in step 2.)

4.) write "read-only" tool doing something usefull with the MDR 
repository loaded with date in step 3 : reporting structures/statistics 
of Java code, viewing Java code in some beter way ( call graphs, 
inheritance structures, ... )

5.) if desired : write tool modifying Java code in MDR using interfaces 
from step 2.) => also "read-only tool" for generating of Java code from 
MDR repository would be needed to have changes reflected in Java programs

Classes you defined seems to be actually MOF meta-classes for Java 
langauge which could be automatically generated from Java metamodel.
