JAXB Marshalling - Reference is pulling and inserting entire object details inside XML

I'm trying todo JAXB marshalling and running with strange problem. I have three objects in one xml named Column, Row and Table

The table element has references to Column ID and Row ID. In Hibernate, I've one -to-one relation mapped (via many-to-one relationship))

When I generate the xml, I see that in place of ID, the entire record detail tag is getting inserted in my xml.

What I want:

<Hierarchy name="" desc="" title="" >
    <Column>
         <Column name="" desc="" group="" id=""/>
    </Column>
    <Row>
        <Row id =1 name=" " desc="" id="">
           <Row id = 2 name="" desc="" id="" />
        </Row>
        <Row id = 3 name=" " desc="" id="" />
    </Rows>
    <table>
         <table name="" RowID="" measureID="" filter="" expression="" product="" dataset="" datatype="" subreport="" />
    </table>
</Hierarchy>

What I'm getting

<Hierarchy name="" desc="" title="" >
    <Column>
         <Column name="" desc="" group="" id=""/>
    </Column>
    <Row>
        <Row id =1 name=" " desc="" id="">
           <Row id = 2 name="" desc="" id="" />
        </Row>
        <Row id = 3 name=" " desc="" id="" />
    </Rows>
    <table>
         <table name=""  filter="" expression="" product="" dataset="" datatype="" subreport="" 
         <name =""/>
         <RowID>
            <id>1</id>
            <name></name>
            <desc></desc>
        </RowID>
        <measureID>
            <id>1</id>
            <name></name>
            <desc></desc>
         </table>
..............
    </table>
</Hierarchy>

I've defined the following relationship in my hibernate mapping file

 <many-to-one name="RowID" column="RowName" 
    class="com.abc.Row" cascade="save-update" lazy="false" not-null="false"></many-to-one>

<many-to-one name="ColumnID" column="ColumnName" 
    class="com.abc.Column" cascade="save-update" lazy="false" not-null="false"></many-to-one> 

In class I've defined the relationship as

public class Table{
private id;
private Row rowID;
Private Column columnID;

..getters/setters
}

Can somebody pls advise as I'm new to JAXB
