java json2xml,将JSON转换为XML XmlMapper- Jackson 2.10

I have pojos with @JsonProperties. I use these to read JSON and parse to POJO. I am now having to post these pojos formatted as XML.
The Required XML format to successfully post looks like this (note the namespace type, xsi type formatting):
TestSubnet
TestSubnet
false
3
subnet
5.207.206.0
255.255.254.0
Test01Subnets
Test01Subnets
3
group
I pass the created Application Class (shown below) to convert to XML
ObjectMapper mapper = new XmlMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
byte[] val = mapper.writeValueAsBytes(myApp);
The output is a bit off and does not contain the xmlns and the xsi looks different. It also has 'Application' as root:
networkObjectGroupDTO@xsi.type>
name
displayName
3
group
When I output the class to JSON, it looks as expected (No "Application" as root).
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
byte[] val = mapper.writeValueAsBytes(myApp);
{
"network_objects" : {
"network_object" : [ {
"@xsi.type" : "networkObjectGroupDTO",
"name" : "name",
"display_name" : "displayName",
"application_id" : 3,
"type" : "group"
}
}
}
What do I need to modify with my XmlMapper() or POJOs in order to get the XML formatted correctly?
Below are the POJOs used for this.

I used your bean classes and json string. Almost everything is possible with the conversion, but there are some issues. I got this so far, if someone can derive the final solution it will be great.
Application.java
Not really any changes.
