java - JAXB : XmlElementWrapper nested nodes -

i want generate xml :

    <mainnode>           <node1></node1>         <node2></node2>      </mainnode>    <mainnode2></mainnode2>  

and how generate mainnode1 , mainnode2 , node1 in code:

   @xmlelementwrapper(name = "mainnode")         @xmlelement(name = "node1")         public list<string> getvalue() {             return value;         }     @xmlelement(name = "mainnode2")    public string getvalue2() {    return value2;    } 

how add node2 mainnode1 ?

you don't seem have root element in example. obtain structure want:-

@xmlaccessortype(xmlaccesstype.field) @xmlrootelement class node {     private mainnode    mainnode;     private mainnode2   mainnode2;      public node() {     }      public node(mainnode mainnode, mainnode2 mainnode2) {         this.mainnode = mainnode;         this.mainnode2 = mainnode2;     }  }  @xmlaccessortype(xmlaccesstype.field) @xmlrootelement class mainnode {     private string  node1;     private string  node2;      public mainnode() {     }      public mainnode(string node1, string node2) {         this.node1 = node1;         this.node2 = node2;     }  }  @xmlaccessortype(xmlaccesstype.field) @xmlrootelement class mainnode2 {  } 

here's test code:-

jaxbcontext jc = jaxbcontext.newinstance(node.class); marshaller m = jc.createmarshaller();  mainnode mainnode = new mainnode("node1 value", "node2 value"); mainnode2 mainnode2 = new mainnode2(); node node = new node(mainnode, mainnode2);  stringwriter sw = new stringwriter();  m.marshal(node, sw);  system.out.println(sw.tostring()); 

... , here's printout:-

<?xml version="1.0" encoding="utf-8" standalone="yes"?> <node>   <mainnode>      <node1>node1 value</node1>     <node2>node2 value</node2>   </mainnode>   <mainnode2/> </node>
