    <p>I have a Books class with ArrayList of BookMeta objects , the name of the arraylist is bookList.</p> <p>If the bookList holds more than one BookMeta, it works good for the clients as they receive an array. But if there is only one BookMeta object in bookList, they dont receive an array, instead they get one element. I took the following workaround for forcing the output to be one array :</p> <pre><code>@Provider public class JaxbContextResolver implements ContextResolver&lt;JAXBContext&gt; { private JAXBContext context; private Class[] types = {BookMeta.class, Books.class}; public JaxbContextResolver() throws Exception { this.context = new JSONJAXBContext( JSONConfiguration.mapped().arrays("bookList").build(), types); } public JAXBContext getContext(Class&lt;?&gt; objectType) { for (Class type : types) { if (type == objectType) { return context; } } return null; } } </code></pre> <p>Still I am not getting arrays. What else should I do ? Do I need to explicitly register the Provider classes ? I read somewhere they are automatically detected.</p> <p>Thanks.</p> <p>Edit : I am using Tomcat 6, and my web.xml looks like :</p> <pre><code>&lt;servlet&gt; &lt;servlet-name&gt;Jersey REST Service&lt;/servlet-name&gt; &lt;servlet-class&gt;com.sun.jersey.spi.container.servlet.ServletContainer&lt;/servlet-class&gt; &lt;init-param&gt; &lt;param-name&gt;com.sun.jersey.config.property.packages&lt;/param-name&gt; &lt;param-value&gt;resources&lt;/param-value&gt; &lt;/init-param&gt; &lt;load-on-startup&gt;1&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;Jersey REST Service&lt;/servlet-name&gt; &lt;url-pattern&gt;/rest/*&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; </code></pre>

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).
