problem with unmarshal xml to Java object when there is HashMap and Map contains another root element

Hi Expert,

I am new to CXF and met one issue related with HashMap.
It is not the problem of unmarshal and marshal normal HashMap to normal Java
objects. I have created the XML adapter to fix this, the problem is below:

XML

*		<Transaction>  
			<trans>newUpdate</trans>
			<fields>
			        <entries>
				 <key>completedBy</key>
				 <value xsi:type="xs:string">icil-cs</value>
				</entries>
				<entries>
					<key>toDoItemAction</key>
					<value xsi:type="com.icil.cxf.shipment.bean.Transaction">
						<Transaction xsi:type="com.icil.cxf.shipment.bean.Transaction">
							<trans>updateIgnore</trans>
							<fields>
								<entries>
									<key>from</key>
									<value xsi:type="xs:string">scarlett</value>
								</entries>
							</fields>
						</Transaction>
					</value>
				</entries>
			</fields>
		</Transaction>*


The Transaction maps to my Transaction.java class.
after convert the inner Transaction is null
*toDoItemAction=[value: null]*

I search for a day but have not found any solution, can anyone helps on
this?

Hi Freeman,

I already have the Map Adapter class that can handle the xml like

<fields>
 <entry>
  <key>completedBy</key>
  <value xsi:type="xs:string">scarlettxu</value>
 </entry>
</fields>

But when the <value> contains nested piece of xml, then it cannot translate
to Java object
<fields>
 <entry>
  <key>toDoItemAction</key>
  <value xsi:type="Transaction">
*   <Transaction>
    <trans>update</trans>
    <name>ToDoItemActionTO</name>
   </Transaction>*
  </value>
 </entry>
</fields>

Hi,

Please ensure you already take a look at java_first_jaxws example shipped with kit, that example demonstrates how to use adapter class to handle Map.
You can adjust that example to meet your requirement, it should be a good start for you.
