How to get the properties from XML using Jaxb?

Question

I've already tried some approaches but seems to be something on the way I'm doing it. I created a simple Java class:

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "TRANSACTION")
@XmlAccessorType(XmlAccessType.FIELD)
public class CanonicalPropertyJaxb {

    @XmlAttribute
    protected String edbt;

    public String getEdbt() {
        return edbt;
    }

    public void setEdbt(String edbt) {
        this.edbt = edbt;
    }



}

And that's the XML I receive. I need this XML to generate the Java object and the Java object to generate this same XML whenever I need. So I started just trying to get the EDBT property from the TRANSACTION tag, but It's always returning null.

<TRANSACTION ETYPE='JDEMCU' EDUS='IPAAS_ADM' EDBT='16919' EDTN='0' EDLN='2.000' EKEY='IPAAS_ADM-16919-0-2.000'>     <TABLE_1 NAME='F0006Z1' TYPE='1'>       <FORMAT_TABLE_F0006Z1 SEQ="1">

What's the right way to get this information?

Answer 1

JAXB is case sensitive. So either change the field to EDBT , or add the uppercase name to @XmlAttribute(name="EDBT") .

I prefer the later because it matches the java style guideline.
