How can I inject xml value into java interface methods

I need to inject values from xml file into my java code using reflection mechanism, currently I implemented xml parsing mechanism in this way:

 protected Map<String, BasicElement> container = new HashMap<String, BasicElement();
    // contain element instances that appears at xml file

for each class I there is dedicated xml file, that define class values.

here is an example:

java class

public class MerchandiseDesignDialog extends EntityDesignDialog {


    private TextField model;
    private TextField name;
    private TextField description;
    private DropDownList attribute_1;
    private DropDownList attribute_2;
    private DropDownList attribute_3;
    private DropDownList attribute_4;



    private final static String NAME = "Name";
    private final static String DESCRIPTION = "Description";
    private final static String ATTRIBUE_1 = "Attribute (1)";
    private final static String ATTRIBUE_2= "Attribute (2)";
    private final static String ATTRIBUE_3 = "Attribute (3)";
    private final static String ATTRIBUE_4 = "Attribute (4)";

    private static final String XML_FILE_NAME = "/src/main/java/com/merchandiseDesignDialog.xml";



    @Override
    protected void initInnerElements() {
        try {

            this.name = (TextField)container.get(NAME);
            this.description = (TextField) container.get(DESCRIPTION);
            this.attribute_1 = (DropDownList)container.get(ATTRIBUE_1);
            this.attribute_2 = (DropDownList)container.get(ATTRIBUE_2);
            this.attribute_3 = (DropDownList)container.get(ATTRIBUE_3);
            this.attribute_4 = (DropDownList)container.get(ATTRIBUE_4);
        } catch (ClassCastException e) {
            report.reportStatus(this.getClass().getName() + " : initializing elements failed ", Status.FAIL);
        }
    }


    public TextField getName() {
        this.find();
        name.find(this);
        return name;
    }

    public TextField getDescription() {
        this.find();
        description.find(this);
        return description;
    }

    public DropDownList getAttribute_1() {
        this.find();
        attribute_1.find(this);
        return attribute_1;
    }

    public DropDownList getAttribute_2() {
        this.find();
        attribute_2.find(this);
        return attribute_2;
    }

    public DropDownList getAttribute_3() {
        this.find();
        attribute_3.find(this);
        return attribute_3;
    }

    public DropDownList getAttribute_4() {
        this.find();
        attribute_4.find(this);
        return attribute_4;
    }


    /**********************************************************

    public MerchandiseDesignDialog setName(String nameValue) {
        getName().insert(nameValue);

    public MerchandiseDesignDialog setDescription(String descriptionValue) {
        getDescription().insert(descriptionValue);
        return this;
    }


    public MerchandiseDesignDialog selectAttribute_1(String attribute_1Val) throws NoSuchElementException {
        getAttribute_1().select(attribute_1Val);
        return this;
    }

    public MerchandiseDesignDialog selectAttribute_2(String attribute_2Val) throws NoSuchElementException {
       getAttribute_2().select(attribute_2Val);
        return this;
    }

    public MerchandiseDesignDialog selectAttribute_3(String attribute_3Val) throws NoSuchElementException {
        getAttribute_3().select(attribute_3Val);
        return this;
    }

    public MerchandiseDesignDialog selectAttribute_4(String attribute_4Val) throws NoSuchElementException {
        getAttribute_4().select(attribute_4Val);
        return this;
    }

}

detecated Xml file

</ComplexElement>

Code explanation, container include all xml file content, each xml element has a java instance. at each class from I should implement the following:

1. initInnerElements() method, that init each one of the class field, by getting it from container.

2. get method the invoke find methods before return each field.

3. and operation method the invoke get method and do an operation.

after describe the current status, here is The Question:

How can I implement the same code using the following code structure:

@Page(path = "/src/main/java/com/merchandiseDesignDialog.xml")
public interface IMerchandiseDesignDialog {

    @Entity(visibileName = "Name")
    public TextField getName();

    @Entity(visibileName = "Description")
    public TextField getDescription() ;

    @Entity(visibileName = "Attribute (1)")
    public SRODropDownList getAttribute_1() ;

    @Entity(visibileName = "Attribute (2)")
    public SRODropDownList getAttribute_2();

    @Entity(visibileName = "Attribute (3)")
    public SRODropDownList getAttribute_3() ;

    @Entity(visibileName = "Attribute (4)")
    public SRODropDownList getAttribute_4() ;



    /**********************************************************
     * ********************************************************
     ***********************************************************/
    public IMerchandiseDesignDialog setName(String nameValue);

    public IMerchandiseDesignDialog setDescription(String descriptionValue);

    public IMerchandiseDesignDialog selectAttribute_1(String attribute_1Val) throws NoSuchElementException ;

    public IMerchandiseDesignDialog selectAttribute_2(String attribute_2Val) throws NoSuchElementException ;

    public IMerchandiseDesignDialog selectAttribute_3(String attribute_3Val) throws NoSuchElementException ;

    public IMerchandiseDesignDialog selectAttribute_4(String attribute_4Val) throws NoSuchElementException ;


}

And some how the magic is happen in daemon code, that I don't need to write at each class again and again. I need to replace that MerchandiseDesignDialog class, and use an interface that only describe the methods with annotations. I know that java reflection is the correct way but I don't know how to implement it.
