Problem mapping JDO to an existing DB schema

Question

I'm having problems mapping a legacy database to JDO. Suppose I have a class
public class Test {
public int pk;
public String fieldA;
public String fieldB;
public String fieldC;
An existing legacy table TEST looks like
TEST
|============|
| PK | ... |
|============|
| 1 | ... |
|============|
The fields values are stored in a separate table
TEST_FIELDS
|==========================|
| PK | FIELD_ID | VALUE |
|==========================|
| 1 | 1 | fred |
| 1 | 2 | accounts |
| 1 | 3 | jim |
| 2 | 1 | wilma |
| 2 | 2 | research |
| 2 | 3 | alice |
|==========================
So the value for fieldA of an object with key i in the TEST table
would be found in the TEST_FIELDS table with key (i, 1), fieldB with
key (i,2) and fieldC with (i,3) and so on. I'm not sure how I would express
such a mapping in the JDO metadata file, or indeed whether this is
even possible. Any suggestions?

Answer 1

This mapping is not possible in the current incarnation of
Kodo.
