hello,all
as a new jaxb user ,i have the below prolbem,looking for help.
i use xjc to generated the java files and use jaxb Unmarshaller xml to
object, but i can't get all the Unmarshaller objects.
that's is to say i can get the tag {"searchRequest" ,
"query","type1","rpn","rpnRpnOp","rpn1"} representation object. but i can
not get searchRequest>query>type1>rpn>rpnRpnOp>rpn1>rpnRpnOp the last
object rpnRpnOp is null !!!
the related file and codes as below,
1 polan.xml
<?xml version="1.0" encoding="GBK"?>
<searchRequest xmlns="urn:com:zhjy:mltx:egss:1.0">
<referenceId>123</referenceId>

3 i use xjc generate java code success from the xsd.
4 i use below code to Unmarshaller the polan.xml
JAXBContext jc = JAXBContext.newInstance("com.zhjy.mltx.egss");
Unmarshaller u = jc.createUnmarshaller();
JAXBElement customerE = (JAXBElement) u.unmarshal(new FileInputStream(
"c:/test_polan1.xml"));
SearchRequestType srt = (SearchRequestType) customerE.getValue();
QueryType queryType= srt.getQuery();
System.out.println("=============query============");
System.out.println(ToStringBuilder.reflectionToString(queryType));
System.out.println("===============type1==========");
Type1 type1 = queryType.getType1();
System.out.println(ToStringBuilder.reflectionToString(type1));
System.out.println("==============rpn===========");
RPNQueryType rpn0 = type1.getRpn();
ComplexArugmentType cat = rpn0.getRpnRpnOp();
ArgumentType at1= cat.getRpn1();
ArgumentType at2 = cat.getRpn2();
OperatorType ot = cat.getOperator();
RPNQueryType rpn1 = at1.getRpn(); //-----this line get null
ArgumentType at11 = rpn1.getOp(); //-----this line get null
is any where has error? please help me! thanks
