XSD and java object

[pranay hira]

Dear All,

When I have a java object say Person and I have an XSD can I generate an output XML file. I heard a collega saying something about SAX and DOM parsers.
But reading through the API I only see the other way around. Going from XML to a Java object.

Can anyone give me a tip?

Thanks in advance

You have lots of options.

Since XML is just text, you could create output with println type character output statements. It would be up to you to write text compatible with the XSD.

For objects compatible with the JavaBean standard there is the java.beans.XMLEncoder class

Don't expect some magic tool that can look at the XSD and create complete code.

Creating unmarshalling code via an XSD is a largely automatic process via most any JAXB implementation.

okay guess my collegue misunderstood. I did found this:
JAXBContext contextObj = JAXBContext.newInstance(Student.class);
Student myStudent = new Student();
Marshaller marshallerObj = contextObj.createMarshaller();
marshallerObj.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

myStudent.setGender("M");
myStudent.setName("Amar");
myStudent.setAge(20);
marshallerObj .marshal(myStudent, new FileOutputStream("Student.xml"));
