JAXB facilities in unmarshaling

Question

Hello guys how can i unmarshall list of objects in XML. My XML will be like this

<messageContainer class="class1">
    <a>         
        <b />
    </a>
    <MessageB />
</messageContainer>
<messageContainer class="class2">
    <a>         
        <b />
    </a>
    <MessageB />
</messageContainer>

And i want to get list of object in the end.

Any Valid XML file can contain only one XML Root Element.
I assume that u have the above list as a child of an RootElement(say ).

Then your annotated RootElement class should look like this.

 @XmlRootElement(name = "RootElement") public class RootElement{ @XmlElement(name = "messageContainer", required = true) private List<messageContainer> containerList; } 

Where MessageContainer is a class by itself.

Note : The more simpler way to generate these binding class is, write XSD(or generate using online tools) for your XML and compile those XSD with XJC compiler.
