<h1>Running test applications</h1>
<p>After you've <a href="Building.html">downloaded JaxM</a>e and <a
href="GenerateJava.html">generated the Java code</a>, you're ready to run
your test applications. <br>
</p>
<p>In this document, you'll see how to do the following: </p>
<ol>
<li> <a href="#4.%20%20Reading%20XML%20data%20into%20Java">Run
a test application to convert XML data into Java objects</a></li>
<li> <a href="#5.%20Writing%20XML%20data%20from%20Java">Run another
test application to convert Java objects into XML data</a></li>
</ol>
<h2> <a name="4. Reading XML data into Java"></a>1. Reading XML data
into Java objects</h2>
<p>This section describes how to integrate the generated code into your Java
application, which will read data from an XML document into Java objects.
</p>
<p>In this tutorial, we'll use <a
href="../examples/misc/AddressPrinter.java">AddressPrinter.java</a> as our
test application (shown below). This application will take <tt>Address.xml</tt>
as input, generate Java objects, and print the data. </p>
<p>JaxMe imports the Java source code that it had generated (see <a
href="GenerateJava.html">Generating Java code</a>), instantiates <tt>Address</tt>,
and uses the <tt>Unmarshaller</tt> for reading elements. </p>
<pre>import java.io.File;<br>import javax.xml.bind.JAXBContext;<br>import
javax.xml.bind.Marshaller;<br>import javax.xml.bind.Unmarshaller;<br><br>import

AddressPrinter {<br> public static void main(String[] args) throws Exception {<br>
JAXBContext context =
JAXBContext.newInstance("net.sf.jaxme.examples.misc.address");<br> Unmarshaller
unmarshaller = context.createUnmarshaller();<br> Address addr = (Address)
unmarshaller.unmarshal(new File("Address.xml"));<br> if (addr.getName() == null)
{<br> System.out.println("Loaded address without name.");<br> } else {<br>
System.out.println("Loaded address " + addr.getName().getLast() +<br>
", " + addr.getName().getFirst() + ".");<br> }<br>
System.out.println("Details:");<br> Marshaller marshaller =
context.createMarshaller();<br> marshaller.marshal(addr, System.out);<br>
}<br>}<br></pre>
<h2> 2. Writing XML data from Java objects</h2>
As our last step in this tutorial, we run the <a
href="AddressCreator.java">AddressCreator</a> application to create XML data
from Java objects.
<blockquote>
<pre>import java.io.FileWriter;<br>import javax.xml.bind.JAXBContext;<br>import
javax.xml.bind.Marshaller;<br><br>import
net.sf.jaxme.examples.misc.address.*;<br><br><br>public class AddressCreator {<br>
public static void main(String[] args) throws Exception {<br> // Create the
element:<br> Address addr = new AddressImpl();<br> addr.setName(new
NameImpl());<br> addr.getName().setFirst("Jane");<br>
addr.getName().setLast("Doe");<br> addr.setPostal(new PostalImpl());<br>
addr.getPostal().setStreet("34 Main Street");<br>
addr.getPostal().setCity("Boston");<br> addr.getPostal().setState("MA");<br>
addr.getPostal().setZIP("02215");<br> addr.setEmailDetails(new
EmailDetailsImpl());<br><br> Email email = new EmailImpl();<br>
email.setType("Private");<br> email.setEmailAddress("[EMAIL PROTECTED]");<br>
addr.getEmailDetails().addEmail(email);<br> email = new EmailImpl();<br>
email.setType("Private");<br> email.setEmailAddress("[EMAIL PROTECTED]");<br>
addr.getEmailDetails().addEmail(email);<br> email = new EmailImpl();<br>
email.setType("Private");<br>
email.setEmailAddress("[EMAIL PROTECTED]");<br>
addr.getEmailDetails().addEmail(email);<br><br> addr.setPhoneDetails(new
PhoneDetailsImpl());<br> Phone phone = new PhoneImpl();<br>
phone.setType("Work");<br> phone.setPhoneNumber("555.6789");<br>
addr.getPhoneDetails().addPhone(phone);<br><br> // And save it into the file
"Address.xml"<br> JAXBContext context =<br>
JAXBContext.newInstance("net.sf.jaxme.examples.misc.address");<br> Marshaller
marshaller = context.createMarshaller();<br> FileWriter fw = new
FileWriter("Address.xml");<br> marshaller.marshal(addr, fw);<br> fw.close();<br>
}<br>}<br></pre>
