Some problem converting XML to Class using in JAXBContext

I am using JAXBContext for converting XML to Class.
but I had some problem.
1) XML Like this.
<Baseball namespace="Sport">
<League namespace="MLB">
<Description>Baseball league of America</Description>
<Team>
<Name>Yankees</Name>
<City>Newyork</City>
</Team>
<Team>
<Name>Dodgers</Name>
<City>LA</City>
</Team>
</League>
</Baseball>
2) Class like this.
2-1) Baseball.class
#XmlRootElement(name = "Baseball ", namespace = "Sport")
#XmlAccessorType(XmlAccessType.FIELD)
private class Baseball
{
#XmlElement(name = "League", namespace = "MLB")
public League league;
}
2-2) League.class
#XmlRootElement
#XmlAccessorType(XmlAccessType.FIELD)
private class League
{
#XmlElement(name = "Description")
public String description;
#XmlElement(name = "Team")
public Team[] teams;
}
2-3) Team.class
#XmlRootElement
#XmlAccessorType(XmlAccessType.FIELD)
private class Team
{
#XmlElement(name = "Name")
public String name;
#XmlElement(name = "City")
public String city;
}
Baseball and league was converted to class successfully but team is not converted to class.
Also value of description is null.
what's the problem in this code?

Your xml is invalid.
The element "Description" is terminated by a start-tag instead of an end-tag.
In addition, "League" is missing an end-tag.
Here's a valid version of your xml:
<Baseball namespace="Sport">
<League namespace="MLB">
<Description>Baseball league of America</Description>
<Team>
<Name>Yankees</Name>
<City>Newyork</City>
</Team>
<Team>
<Name>Dodgers</Name>
<City>LA</City>
</Team>
</League>
</Baseball>

I generated an XSD file from your (corrected) example XML, using this link, and used xjc to generate classes from it.
I attach the result, so you can compare it to your classes for differences.

Marshalling multiple object entries into a file, using an XML file and generated JAXB helper classes

And the generated JAXB helper class:

And in the Main, using the XML template, I am setting data for the defined elements:
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.logging.Level;
import java.util.logging.Logger;
public class Main {
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
itemOrder.Book quickXML = new itemOrder.Book();
quickXML.setAuthor("Lev Tolstoi");
quickXML.setDescription("Russion fixction about 1st world war");
quickXML.setISBN(62129985);
quickXML.setPrice((float)12.6);
quickXML.setPublisher("Progress");
quickXML.setTitle("War and Peace");
try {
javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(quickXML.getClass().getPackage().getName());
javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller();
marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_ENCODING, "UTF-8"); //NOI18N
marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
OutputStream os = new FileOutputStream("xmlFile.xml");
marshaller.marshal(quickXML, os);
} catch (javax.xml.bind.JAXBException ex) {
// XXXTODO Handle exception
java.util.logging.Logger.getLogger("global").log(java.util.logging.Level.SEVERE, null, ex); //NOI18N
} catch (FileNotFoundException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
and then marshalling them into a file. The question is, how can I marshal multiple entries of the data into ONE file. So for example: I would like to marshal this:
quickXML.setAuthor("Lev Tolstoi");
quickXML.setDescription("Russion fixction about 1st world war");
quickXML.setISBN(62129985);
quickXML.setPrice((float)12.6);
quickXML.setPublisher("Progress");
quickXML.setTitle("War and Peace");
and this:
quickXML.setAuthor("Robert Schwentke");
quickXML.setDescription("description description description");
quickXML.setISBN(62129432);
quickXML.setPrice((float)10.9);
quickXML.setPublisher("Regress");
quickXML.setTitle("Red");
at the same time, into the same file. Any ideas?

You can wrap 'book' elements with a 'books' tag
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://xml.netbeans.org/schema/books"

<xsd:element name="Price" type="xsd:float"/>
<xsd:element name="PublicationYear" type="xsd:int"/>
<xsd:element name="book">

So why is my bean method isAuctionExpired() not in the generated source? I am able to cheat this by adding a auctionExpired property, but this is not how I want to do this.

The JAX-WS client is generated using the WSDL of the webservice. The WSDL only has the properties of the types that will be used for communication between the server and the client. So, you will never be able to pass the method implementation across server and client. The information in the below annotation is all the client class generator has while generating the client;
#XmlType(name = "auction", propOrder = {
"added",
"expire",
"id",
"product",
"reserve",
"startingBid"

This information is taken from the WSDL.
You have to understand that XML is used for communication between the server and the client. So, code from the webservice cannot be passed to the client or vice versa. The webservice and the client can be written in two different technologies. So, passing java code to the client does not make any sense if the client is implemented in any other language.
In short, you can pass information between the client and server but not behaviour.

XML Request Jaxb

I am trying to make a Java object out of an xml request using Jaxb but my limited knowledge of jaxb is holding me back. I have done this before but it was with simple XML documents only using basic Elements such as
<RootElement>
<Bookname>Moby Dick</Bookname>
<BookCode>1</BookCode>
</RootElement>
But now I have a bit more complicated of an xml file and any help getting me started on how to create this object would be greatly appreciated. I think I will have to use some sort of list, along with #Xmlattribute, but am just confused at the moment. Any help would be greatly appreciated! I hope I am not just overthinking this. The sample XML is found below:
<?xml version="1.0"?>
<CRMMessage language="en_US" currency="USD" >
<RequestSource name="Testsource" version="2" />
<RequestCode>GetTest</RequestCode>
<DataSet>
<DataSetColumns>
<DSColumn name="Column1" />
<DSColumn name="Column2" />
</DataSetColumns>
<Rows>
<Row>
<Col>John</Col>
<Col>Doe</Col>
</Row>
</Rows>
</DataSet>
</CRMMessage>

I have knocked you up a quick schema, this may not be exactly what you need as I cannot tell from the example data whether more than one or certain elements it allowed etc:
<xs:schema version="1.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:element name="CRMMessage">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="1" name="RequestSource">
<xs:complexType>
<xs:attribute name="Testsource" type="xs:string"/>
<xs:attribute name="version" type="xs:integer"/>
</xs:complexType>
</xs:element>
<xs:element minOccurs="1" maxOccurs="1" name="RequestCode" type="xs:string"/>
<xs:element minOccurs="1" maxOccurs="1" name="DataSet">
<xs:complexType>
<xs:all>
<xs:element minOccurs="1" maxOccurs="1" name="DataSetColumns">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="DSColumn">
<xs:complexType>
<xs:attribute name="name" type="xs:string"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element minOccurs="1" maxOccurs="1" name="Rows">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="Row">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="Col" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:all>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="language" type="xs:string"/>
<xs:attribute name="currency" type="xs:string"/>
</xs:complexType>
</xs:element>
</xs:schema>
You should be able to use that as a starting point.
I then compiled that into a class using xjc via the maven plugin and the following in my pom:
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.8.2</version>
<executions>
<execution>
<id>bind-crm</id>
<configuration>
<schemaDirectory>src/main/resources/</schemaDirectory>
<generatePackage>com.my.package.crm</generatePackage>
<forceRegenerate>true</forceRegenerate>
</configuration>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
</plugin>

That help?

Creating an XML schema for your XML and generating a model from it is definitely as answered by bmorris591 is definitely one way to go. But your XML document isn't so complicated that you can't start from objects.
CRMMessage
We use the #XmlRootElement annotation to map our root object to the root element of the document.
By default JAXB (JSR-222) implementations look for metadata on the public properties (get/set methods). To save space I have set #XmlAccessorType(XmlAccessType.FIELD) to specify that the metadata is on the fields (see: http://blog.bdoughan.com/2011/06/using-jaxbs-xmlaccessortype-to.html)
The #XmlAttribute annotation is used to specify that a field/property maps to an XML attribute.
By default all fields/properties map to XML elements. If the default XML name does not match your desired mapping then you can use the #XmlElement annotation to override the name.
import javax.xml.bind.annotation.*;
#XmlRootElement(name="CRMMessage")
#XmlAccessorType(XmlAccessType.FIELD)
public class CRMMessage {
#XmlAttribute
private String language;
#XmlAttribute
private String currency;
#XmlElement(name="RequestCode")
private String requestCode;
#XmlElement(name="DataSet")
private DataSet dataSet;
}
DataSet
One advantage of starting from Java classes is that you can leverage the #XmlElementWrapper annotation to add a grouping element on your collection fields/properties (see: http://blog.bdoughan.com/2010/09/jaxb-collection-properties.html). Compare this with the generated DataSet class https://stackoverflow.com/a/14986770/383861.
import java.util.List;
import javax.xml.bind.annotation.*;
#XmlAccessorType(XmlAccessType.FIELD)
public class DataSet {
#XmlElementWrapper(name="DataSetColumns")
#XmlElement(name="DSColumn")
private List<DSColumn> columns;
#XmlElementWrapper(name="Rows")
#XmlElement(name="Row")
private List<Row> rows;
}

How can i unmarshal with JAXB

I have some problem when unmarshaling a .xml at a web service using JAXB.
This is the .xml file being sent from some client to the web service.
<?xml version="1.0" encoding="UTF-8"?>
<PERSON xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="file:/D:/MyWorkSpace/JAVA%20WEB%20Services%20DEVELOPER/XML%20Workspace/Persons.xsd">
<NAME>Michael</NAME>
<AGE>12</AGE>
<ADRESS>
<STREET>Somewhere in Spain</STREET>
<ZIP>47015</ZIP>
</ADRESS>
<HOBY indoorHoby="true"/>
</PERSON>
This is the method that does the unmarshaling
#POST
#Path("/XMLArrivalBeacon")
#Consumes(MediaType.APPLICATION_XML)
public Response methodI(String content) {
System.out.print(content);
try {
//Unmarshaling
JAXBContext context = JAXBContext.newInstance(Person.class);
Unmarshaller unmarshaller = context.createUnmarshaller();
//Unmarshal the String
Person person = (Person) unmarshaller.unmarshal(new StreamSource(new StringReader(content)));
//Checking that the values were recieved ok
System.out.print(person.getName());
return Response.ok("XML recieved from client!!!").build();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
Here is the person class annotated with the JAXB annotations(Was automatically generated from the Schema)

Any idea how can i fix it?

Your xml does not match your schema. xml element names are case sensitive. "PERSON" and "Person" are not the same element.
