Create a custom binder for Jaxb

I have an XML file I want to parse into an object with Jaxb. I have created the objects according to the XML file I receive, and annotated the getters to setup the binding.

The purchase date is coming in as a yyyyMMdd format, and this is not parsed correctly. I searched around a bit, and it seems I need to create a custom Jaxb binder.

Can anyone give me a jump-start on how i need to create this custom binder ?

Thanks

@XmlType(name = "PRODUCTSHORT")
public class ProductShort {
	private String modelCode;
	private String serialNo;
	private MyDate purchaseDate;
 
	@XmlElement(name = "MODEL_CODE")
	public String getModelCode() {
		return modelCode;
	}
 
	public void setModelCode(String modelCode) {
		this.modelCode = modelCode;
	}
 
	@XmlElement(name = "SERIAL_NO")
	public String getSerialNo() {
		return serialNo;
	}
 
	public void setSerialNo(String serialNo) {
		this.serialNo = serialNo;
	}
 
	@XmlElement(name = "PURCHASE_DATE")
	public MyDate getPurchaseDate() {
		return purchaseDate;
	}
 
	public void setPurchaseDate(MyDate purchaseDate) {
		this.purchaseDate = purchaseDate;
	}
}

Works perfectly !!!

I created a MyDateXmlAdapter to convert the incoming date (String) to the MyDate class. And on the MyDate class I added following annotation: @XmlJavaTypeAdapter(MyDateXmlAdapter.class)

import java.text.DateFormat;
import java.text.SimpleDateFormat;
 
import javax.xml.bind.annotation.XmlTransient;
import javax.xml.bind.annotation.adapters.XmlAdapter;
 
@XmlTransient
public class MyDateXmlAdapter extends XmlAdapter<String, MyDate> {
	private DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
 
	@Override
	public MyDate unmarshal(String s) throws Exception {
		if (s != null && s.length() > 0) {
			MyDate dt = new MyDate();
			try {
				dt.setTime(dateFormat.parse(s).getTime());
			} catch (Exception e) {
			}
			return dt;
		} else {
			return null;
		}
	}
 
	@Override
	public String marshal(MyDate date) throws Exception {
		if (date != null) {
			return dateFormat.format(date);
		} else {
			return null;
		}
	}
}
