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;

		}

	}

}
