I am trying to convert a java bean object into xml i.e marshalling.
However when i run my main program,it gives the error
"Exception in thread "main" javax.xml.bind.JAXBException: Unable to locate jaxb.properties for package com"
How is this jaxb.properties file generated?
my code is as follows.i m able to see the address.xml file i.e being created bit it is empty.

package com;

import java.io.FileWriter;
import java.io.Writer;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

//import com.AddressBean;

public class AddressCreator {

public static void writeAddress(Writer pWriter) throws JAXBException {
// Create the element:

com.AddressBean addr = new com.AddressBean();

JAXBContext context = JAXBContext.newInstance("com");
Marshaller marshaller = context.createMarshaller();
marshaller.marshal(addr, pWriter);

public static void main(String[] args) throws Exception {
FileWriter fw = new FileWriter("Address.xml");

Please help as I am stuck at this point.

Check this link...Why am I seeing "Unable to locate jaxb.properties for package aaa.bbb.ccc."?

I'm having the same Exception problem, I put in JAXBContext.newInstance("com.abc.ccc", this.getClass().getClassLoader() ) and I still get the same Unable to locate jaxb.properties for package com.abc.ccc exception.

You need to make sure that jaxb.properties and bgm.ser files(which are generated by xjc tool) are under your "com" directory when you used JAXBContext.newInstance("com").

Dear wise owen

my jaxb.properties and bgm.ser file are there in the classpath.
And also there in the folder that you have specified.

Can you please look at the following link :


And suggest, what I am doing wrong...

Got the soution to my problem...Actually it was required to give the classLoader as the second argument.
Use the overloaded method of newInstance.

Something of this sort
