JAXB.NewInstance requires jaxb.properties in JAXB 2.0

The XJC in JAXB 2.0 does not generate the jaxb.properties file, but the JAXBContext.NewInstance requires it.
I am sure that the old JAXB is not installed on my machine, because I just got a new machine and only installed the JAXB 2.0.
I am using Oracle JDeveloper on Windows XP and I have the following environment vars:
JAVA_HOME=C:\Oracle\10g\jdk\jre
JAXB_HOME=C:\Oracle\10g\jaxb
CLASSPATH=c:\oracle\10g\jaxb\lib\jaxb-api.jar;c:\oracle\10g\jaxb\lib\jaxb-impl.jar;c:\oracle\10g\jaxb\lib\jaxb-xjc.jar + some other files
My code is nothing special:
JAXBContext loJAXBContext = JAXBContext.newInstance("si.ixtlan_team.bibliotheque2.materialdata");
Did anyone have a similar problem and knows the solution?
Thanks,
Bogdan

Can you please let me know how did you solve it. I ahve the same problem in jdeveloper. even though I load jaxb2.0 library manually, runtimr jdeveloper picks up 1.o library.
Thanks

JAXB Namespace Requirements

I was able to solve the unexpected root element error by including the namespace in the xml. Is there a way to configure JAXB to work with or without the namespace?

JAXB 1.0 Throws Exception and WebLogic Server Goes Mad !

Hi,
I've currently got JAXB Running within a standalone application running on Tomcat/Apache.
When I try and Jar it up and run it on Weblogic 7.0 I get the following error being shown.
The JAXB is being called from the onMessage event in a MessageDrivenBean which is sat on the application server. When it received the first message the server logs go mad repeatedly printing out the info below.

public class JAXBClassLoader extends ClassLoader{
public URL getResource(String name){
if (name.endsWith("jaxb.properties")){
name="jaxb.properties";
return super.getResource(name);
snippet of code and then changing the context to be
JAXBContext jc = JAXBContext.newInstance("package structure.........messageinbound.helpers.test",new JAXBClassLoader());
but this does not seem to help - any ideas please ???????

Got Passed the first problem by correctly placing jaxb jars on the server and then sorting out the property file location but I still get the following problem.

I see a number of other postings are talking about this - has anyone got a solution yet ?

JAXB library error in oepe indigo 11.1.1.7.3.201107052114-win32

I have an project that use JAXB parsing libraries. This project was developed for the first time in eclipse oepe 11.1.1.7.2.201104061504-win32 released in April 2011. After I upgraded oepe to the new version, released in July 2011 I have the following library error: The currently selected JAXB library provider is invalid. The jars used is jaxb1-impl.jar, jaxb-api-2.2.4.jar, jaxb-impl-2.2.4-1.jar and jaxb-xjc-2.2.2.jar.
Edited by: 874638 on 24.07.2011 04:51

The Eclipse Indigo release offers some new JAXB tooling from the Dali project (which is part of Web Tools Platform). You are now able to create a JAXB Project.
Configuration
A JAXB project can be configured to use the reference or EclipseLink MOXy implementation of JAXB. This can be done via:
1.Right click your JAXB Project
2.Select Properties
3.Select Project Facets
4.Check the JAXB facet (If you are using Java SE 6 set the JAXB version to 2.1, if you are using Java SE 7 then set the JAXB version to 2.2).
5.Click the "Further configuration required" or "Further configuration available" links.
Using the JAXB RI
-Choose Generic JAXB as your platform
-Choose JRE as your JAXB Implementation Type
Using EclipseLink JAXB (MOXy)
-Choose EclipseLink JAXB as your platform
-Choose User Library as your JAXB Implementation
-Click the Manage Libraries... icon
-Add a new User Library for EclipseLink (the binary can be obtained from http://www.eclipse.org/eclipselink/downloads/). -

JAXB, Castor and extending behaviour

I need to do XML data binding and have been evaluating Castor and JAXB. One of the main differences seems to be Castor is class based while JAXB is interface based.
The ability to generate classes to marshal, unmarshal, and validate is really great but a schema can't define all the behaviour your class may want to have.
Given that the auto-generated classes dont have all the methods I need what do I do? Well in Castor its easy, I just subclass the auto-generated classes and add the behaviour as required. It works well. How can I do a similar thing in JAXB? Extending the interface isnt enough because you need to extend a class to implement the new interface However, in JAXB the implementation class is not supposed to be used directly by the application.
Can anyone suggest the best way to solve this problem?
Thanks,
Paul

One thing I am doing now is generating all the classes initially using the default behaviour. Then I take the one of the generated classes and modify it. Then I create an entry in the binding file specifying the class as the impl class for that node. You can then rerun the generator and it will not write over the class you have changed. I don't see why you couldn't just extend the class and set the extended class name in the binding file. That's actually better than what I've got now because I can keep my methods separate from the generated class and it's easier to regenerate that class too.
My question is whether there is a way to get JAXB to create bound properties the way that you can with Castor?

25 errors
I want all three files to compiled successfully.If it is compiled only then I will continue on Unmarshalling process

I suspect you are trying to compile the files one by one. You may also be trying to compile them disregarding the package structure.
From your post, I gather these files are in the package: com.geindustrial.sqms
Therefore, if they are not so already, put them under a directory structure:
com/geindustrial/sqms
and then compile with:
javac com/geindustrial/sqms/AddCtq.java com/geindustrial/sqms/Ctq.java com/geindustrial/sqms/VariableData.java
(The above is all on one line.)

JAXB Demo Crashes - using JDK 1.4.2

I have installed the pack (1.6) with JDK 1.4.2. That finished 'ok'.
Now I am getting the error: [java] java.lang.NoSuchMethodError: javax.xml.parsers.SAXParserFactory.getSchema()Ljavax/xml/validation/Schema;
when trying to run the bind choice jaxb demo.
As far as I can tell the javax.xml libraries in the java jdk1.4 are too old. How will this work with jdk 1.4 ?
Thanks.

Just FYI -
(This issue is also discussed in this forum, named Java Forums - JAXB JDK requirement.)
I had a hard time trying to figure out the -D and the build file config. I am using Eclipse 3.1, so it is supposed to take care of all this for me, right?
In Eclipse, if you click on the right side of the Run button to open it up, then from the dropdown select Run, a new window will open up that has all of your projects displayed. Select your JAXB project (which might already be highlighted) and you'll see some tabs.
Select the Classpath tab.
Here you'll see Bootstrap Entries. On the right you'll see an Add Jars button. Click on it.
Add the JAXB and JAXP jar files, per the Sun specs:
jaxb-api.jar
jaxb-impl.jar
jaxb-libs.jar
jaxb-xjc.jar
jaxp-api.jar
dom.jar
sax.jar
xalan.jar
xercesImpl.jar
....basically all the jars in the JAXB and JAXP lib directories, including the endorsed files, will do.
This will take care of this issue with JAXB and the 1.4.2 issue when you use Eclipse 3.1. Hope this helps, as it took an experienced Eclipse developer to show me this...

How can I use JAXB on Java 1.4?

My code is developed on 1.4 and my firm has not upgraded to 1.5 yet.
Can I use JAXB?
All I see on web is JAXB2.0 hat requires Java 1.5.
What can I do? Is there any pre-2.0 release of JAXB - I am sure they had JAXB before Java 1.5
Please shed some light, thanks.

https://jaxb.dev.java.net/servlets/ReadMsg?list=users&msgNo=4868
Turadg Aleahmad:
Could JAXB2 work in JSE 1.4 if it was run through Retrotranslator?
http://retrotranslator.sourceforge.net/
Kohsuke Kawaguchi:
It isn't officially supported, but it actually works. Yes, use retrotranslator.
You'd also have to use @xexplicitAnnotation="true" (for Ant) and use
-XexplicitAnnotation for CLI to work around some of the issues.

Help in Java XML Binding (JAXB)

Looking for a JAVA written program that will provide interface to complex XML files using JAXB.
Requirement : JAVA progam will report on existing XML using a simple GUI that will run on Windows. Program should be able to be emailed and installed with all components including XML files and schema. Purpose of this program is twofold.

Sir,
It is bad to expect people to solve assignments for you. Would you elaborate on where you are stuck?

JAXB for previous versions of Java

Will JAXB work with previous versions of Java. Say like Java 1.3 ?

JAXB runtime ClassNotFoundException

I'm trying to set up some really basic build stuff using ant and JAXB to handle the transforming of some XML data, but I'm having some trouble getting it to not throw exceptions at runtime. I've successfully got an XJC task running in ant that is definitely outputting all the correct java classes, and they compile without an issue.
The problems occur when I either try to unmarshall or marshall any data using a JAXBContext. basically, my code looks something like this:
public class Deserializer<T>
 private JAXBContext m_context;
 private Unmarshaller m_unmarshaller;
 public Deserializer(String contextPath)
 try
 JAXBContext m_context = JAXBContext.newInstance(contextPath);
 Unmarshaller m_unmarshaller = m_context.createUnmarshaller();
 catch (JAXBException e)
 System.out.println(e);
 public T deserialize(File xml)
 try
 return (T)m_unmarshaller.unmarshal(new FileInputStream(xml));
 catch (FileNotFoundException e)
 System.out.println(e);
 catch (IOException e)
 System.out.println(e);
 catch (JAXBException e)
 System.out.println(e);
 return null;
}and the exception that I am seeing when the unmarshal function is called is this:

}This is what i'm trying to do im my main class:
FastrackProductImpl po = new FastrackProductImpl();
po.setCode("1234567890");
po.setDeliveryName("Delivery name");
po.setDescription("Description");
po.setPriceInCents(1000);
po.setUid("0987654321");
po.setFastrackProductId("FSID1234");
FileOutputStream mout = new FileOutputStream("fastrackProduct.xml");
marshaller.marshal(po, mout);
mout.close();

Thanks a lot!
Btw, are all the tags that a .xjs file takes documented anywhere??
Its feels rather silly to struggle so much for little things.(Moreover, I am an XML rookie ...so I don't have much f an instinct when it comes to that!)
Thanks again.

JAXB behaviour when unmarshalling documents with an encoding declaration

The following is against JWSDP-1.5, 1.4.2_07-b05 on XP Pro SP 2...
When I unmarshall a document using JAXB 1.0, and obtain Strings from the resulting objects, I would expect the Strings to be encoded with the character encoding specified by the text declaration. Is this a correct assumption?
Unfortunately, from the sample code (given below) I am not experiencing this behaviour. I've included the code, sample output, and the RELAX NG schema used.
Any help very welcome.

JAXB problems unmarshalling

I used xjc to generate a set of elements from the schema shown below:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.doc.state.nc.us/doccodes" xmlns="http://www.doc.state.nc.us/doccodes" xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
 <xsd:element name="codeTable" type="CodeTable"/>
 <xsd:element name="codeRequest" type="CodeRequest"/>
 <xsd:complexType name="CodeTable">
 <xsd:sequence>
 <xsd:element name="codename" type="xsd:string"/>
 <xsd:element name="codes" type="Codes"/>
 </xsd:sequence>
 </xsd:complexType>
 <xsd:complexType name="Codes">
 <xsd:sequence>
 <xsd:element name="code" type="Code" minOccurs="1" maxOccurs="unbounded"/>
 </xsd:sequence>
 </xsd:complexType>
 <xsd:complexType name="Code">
 <xsd:sequence>
 <xsd:element name="identifier" type="xsd:string"/>
 <xsd:element name="description" type="xsd:string"/>
 </xsd:sequence>
 </xsd:complexType>
 <xsd:complexType name="CodeRequest">
 <xsd:sequence>
 <xsd:element name="application" type="xsd:string"/>
 <xsd:element name="token" type="xsd:string"/>
 <xsd:element name="codename" type="xsd:string"/>
 </xsd:sequence>
 </xsd:complexType>
</xsd:schema>
I have successfully been able to marshall an xml file using the following code:
jc = JAXBContext.newInstance( "nc.doc.nexus.code.jaxb.model");
CodeTable codeTable = new CodeTable();
Codes facilityCodes = new Codes();
List<Code> codeList = facilityCodes.getCode();
codeList.addAll(persistables); // where persistables is an ArrayList of Code objects
codeTable.setCodes(facilityCodes);
codeTable.setCodename("facilityCode");
JAXBElement<CodeTable> codeTableElement = (new ObjectFactory()).createCodeTable(codeTable);
Marshaller m = jc.createMarshaller();
m.setProperty( Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE );
m.marshal(codeTableElement, System.out);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db;
try {
db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
m.marshal(codeTableElement, doc);
return doc;
catch (ParserConfigurationException e) {
The marshalling works just fine, and results in the following xml:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:codeTable xmlns="http://www.doc.state.nc.us/doccodes" xmlns:ns1="http://www.doc.state.nc.us/doccodes">
<ns1:codename>
facilityCode </ns1:codename>
<ns1:codes>
<ns1:code>
<ns1:identifier>
X001 </ns1:identifier>
<ns1:description>
DHO DISTRICT 1 </ns1:description>
</ns1:code>
<ns1:code>
<ns1:identifier>
X002 </ns1:identifier>
<ns1:description>
DHO DISTRICT 2 </ns1:description>
</ns1:code>
<ns1:code>
<ns1:identifier>
X003 </ns1:identifier>
<ns1:description>
DHO DISTRICT 3 </ns1:description>
</ns1:code>
</ns1:codes>
</ns1:codeTable>
My code to unmarshall this xml document is as follows:
JAXBContext jc;
try {
jc = JAXBContext.newInstance( "nc.doc.nexus.code.jaxb.model");
Unmarshaller unmarshaller = jc.createUnmarshaller();
JAXBElement<CodeTable> codeTableElement =
(JAXBElement<CodeTable>)unmarshaller.unmarshal(aDocument);
catch (JAXBException e) {
 throw new DeserializerException(e);
Now the problem. When I attempt to unmarshall this xml, I get the following UnmarshalException:
unexpected element (uri:"", local:"ns1:codeTable"). Expected elements are <{http://www.doc.state.nc.us/doccodes}codeRequest>,<{http://www.doc.state.nc.us/doccodes}codeTable>
I've made countless attempts to alter the unmarshal code in an attempt to determine if I had just coded it wrong, or whether jaxb is not able to interpret namespaces or schemas correctly. I have to assume the latter at this point. Can anybody shed any light on this?
By the way, below is the xjc generated class CodeTable:

UPDATE: I changed the unmarshal code to unmarshal a File instead of a DOM Document, and it works. This is the revelation I was hoping not to come to. I really don't want to have to serialize my Document to a file and then unmarshal that file from disk. This would not be an acceptable solution for a large J2EE application with many web services servicing 10000 clients. Does anybody know why the unmarshal method that accepts a DOM Document does not work?

Update JAXB version?

Is it possible to update JDeveloper 10.1.3 to use JAXB 2.0 for its tools?
I've created a web service from a WSDL but the classes generated from JAXB in no way match the JAXB 2.0 versions of the classes.

For example, this is what JDeveloper gives me:
public class Request implements java.io.Serializable {
 protected long ID;
 public Request() {
 public long getID() {
 return ID;
 public void setID(long ID) {
 this.ID = ID;
}and JAXB 2.0 gives me
@XmlAccessorType(AccessType.FIELD)
@XmlType(name = "Request")
public abstract class Request {
 @XmlAttribute(name = "ID", required = true)
 protected long id;
 @XmlAnyAttribute
 private Map<QName, String> otherAttributes = new HashMap<QName, String>();
 * Gets the value of the id property.
 public long getID() {
 return id;
 * Sets the value of the id property.
 public void setID(long value) {
 this.id = value;
 * Gets a map that contains attributes that aren't bound to any typed property on this class.
 * 
 * the map is keyed by the name of the attribute and
 * the value is the string value of the attribute.
 * the map returned by this method is live, and you can add new attribute
 * by updating the map directly. Because of this design, there's no setter.
 * @return
 * always non-null
 public Map<QName, String> getOtherAttributes() {
 return otherAttributes;
}

JAXB.NewInstance requires jaxb.properties in JAXB 2.0
