    <p>I'm trying to annotate a set of data objects with JAXB binding annotations so that this set of data objects can be properly marshaled as JSON using CXF. I'm running into an issue with a class that is basically just a wrapper around ArrayList:</p> <pre><code>class IntegerListWrapper { private ArrayList&lt;Integer&gt; integerList; ... } </code></pre> <p>Some of my data objects refer to this class:</p> <pre><code>class DataObjectFoo { ... public IntegerListWrapper getDataIDs() { ... } ... } </code></pre> <p>I'm looking for the output to be:</p> <pre><code>"DataObjectFoo" : { "dataIDs" : [1, 2, ..., n] // Array of Data IDs } </code></pre> <p>I tried annotating the IDList class itself but it left me with this:</p> <pre><code>"DataObjectFoo" : { "dataIDs" : { "integerList" : [1, 2, ..., n] } // Extra nesting } </code></pre> <p>I tried writing an XmlAdapter but got mixed results:</p> <pre><code>// Throws an error... "Can't bind to interface" public final class IDListAdapter extends XmlAdapter&lt;List&lt;Integer&gt;, IDList&gt; { // Does not produce any output public final class IDListAdapter extends XmlAdapter&lt;ArrayList&lt;Integer&gt;, IDList&gt; { // Produces output with extra nesting like above public final class IDListAdapter extends XmlAdapter&lt;Integer[]&gt;, IDList&gt; </code></pre> <p>So I have two questions:</p> <ol> <li>How do I get the desired output (without converting IDList to something else in my data objects)?</li> <li>Why did the second XmlAdapter (using ArrayList) not produce output?</li> </ol>

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.
