How I convert OMElement to and from java.util.Map and java.util.List object?

[Chatree Srichart]

I would like to use Axis2 send OMElement that contain Map and List data
object like this

For Map object

<mapName>
    <item>
        <name>firstName</name>
        <value>Chatree</value>
    <item>
    <item>
        <name>lastName</name>
        <value>Srichart</value>
    <item>
</mapName>

For List object

<listName>
    <item>
        Item 1
    </item>
        Item 2
    </item>
</listName>

And need to convert Map and List to XML data and convert XML data back to
java object.

Can any one help me?

Thank you very much.
