    <p>I am trying to parse an xml through JAXB which contains xmlns attribute. If I parse the xml as such it shows <code>NullPointerException</code>. But if I remove namespace tags and xmlns attributes then it worked fine. Sample xml is as follows:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;database xmlns="http://www.Example/Database" xmlns:layout="http://www.Example/Layouter"&gt; &lt;namespace name="X1"&gt; &lt;layout:record name="My_Layout" src="screen1.layout" /&gt; &lt;/namespace&gt; &lt;LayoutGroup xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" LayoutGroupID="ID_1"&gt; &lt;/LayoutGroup&gt; &lt;/database&gt; </code></pre> <p>and my sample code is as follows:</p> <pre><code>@XmlRootElement(name = "database") public class database { private LayoutGroup layoutGrp; @XmlElement(name = "LayoutGroup") public void setLayoutGrp(LayoutGroup gp) { layoutGrp = gp; } public LayoutGroup getLayoutGroup() { return layoutGrp; } } </code></pre> <p>Another class:</p> <pre><code>@XmlRootElement (name="LayoutGroup") public class LayoutGroup { String id; @XmlAttribute (name="LayoutGroupID") public void setId(String id) { this.id = id; } public String getId() { return id; } } </code></pre> <p>Here's my main method:</p> <pre><code>public static void main(String[] args) { database db = JAXB.unmarshal(new File("./res/test.xml"),database.class); System.out.println("Layout id is: "+db.getLayoutGroup().getId()); } </code></pre> <p>Could anyone please help to parse the original xml?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
