    <p>There is nothing in your schema that says that the schema itself should be added to the instance document.</p> <p>You would need something like:</p> <pre><code>&lt;xs:element name="transaction" msdata:IsDataSet="true" msdata:UseCurrentLocale="true"&gt; &lt;xs:complexType&gt; &lt;xs:choice minOccurs="0" maxOccurs="unbounded"&gt; &lt;!-- Adding an element that can supports the schema definition --&gt; &lt;xs:element ref="xs:schema" minOccurs="0" maxOccurs="1"/&gt; &lt;!-- and from here on, what you already have : --&gt; &lt;xs:element name="id"&gt; &lt;xs:complexType&gt; &lt;xs:sequence&gt; &lt;xs:element name="in" type="xs:string" minOccurs="0" /&gt; &lt;xs:element name="sn" type="xs:string" minOccurs="0" /&gt; &lt;xs:element name="book" type="xs:string" minOccurs="0" /&gt; &lt;xs:element name="author" type="xs:string" minOccurs="0" /&gt; &lt;/xs:sequence&gt; &lt;/xs:complexType&gt; &lt;/xs:element&gt; ... </code></pre> <p>And then you'd have to insert the schema into your transaction JAXB object for it to show up in your instance document.</p> <p>Now, I would like to know more about your use case: are you sure you need to do this ? The document itself (the transaction XML) could simply specify the schema it conforms to, and even specify a location e.g. :</p> <pre><code> &lt;transaction xmlns="urn:mytransactionschema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.example.com/transaction.xsd" &gt; </code></pre> <p>This should give consumers of your instance document the ability to validate the XML better than by including it in the instance doc.</p>

    2. COcan you tell me how i send this schema object as well as marshalling the schema by which I can generate the xml file with schema.

    3. COThe issue is that adding the schema itself in the instance document makes the latter fail the validation against the former that's plain wrong possibly). That's why your JAXB objects won't have the API to do it out of the box. I assume you can't change the schema anyway since there is an app that consumes it (and that you can't change by yourself). I would use XSLT one way or another to 'inject' your (static) schema into your marshalled document (there are quite a few posts on this site that will help you achieve that).

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.
