== What is it?

The `xml-jaxp` quickstart is a simple Java EE JAXP example that demonstrates how to use Servlet 3.0 and JSF to upload an XML file to _{productNameFull}_ and parse it using DOM or SAX, both of which are built into Java. It also shows how to use modules available in {productName}.

This quickstart provides an example XML schema and document file to use when testing this quickstart.

* The XML schema is located here: `__QUICKSTART_HOME__/src/main/resources/catalog.xsd`
* The XML document is located here: `__QUICKSTART_HOME__/src/main/resources/catalog.xml`

== Access the Application

The application will be running at the following URL: http://localhost:8080/{artifactId}/.

To test the quickstart, follow these steps.

. Click the *Browse* button and navigate to the `__QUICKSTART_HOME__/src/main/resources/catalog.xml` file.
. Click the *Upload* button. The XML file content is parsed and displayed on the page.
. You should see the following output in the server console that shows the DOMXMLParser was used:
+
[source,options="nowrap"]
----
INFO  [stdout] (http-/127.0.0.1:8080-1) Parsing the document using the DOMXMLParser!
----

To enable the alternative SAXXMLParser parser:

. Remove the comments that surround the alternate parser element in the `WEB-INF/beans.xml` file.
. Redeploy the application using the instructions above and access the application in a browser at the following URL: http://localhost:8080/{artifactId}/.
. Click the *Browse* button and navigate to the `__QUICKSTART_HOME__/src/main/resources/catalog.xml` file.
. Click the *Upload* button. The XML file content is parsed and displayed on the page.
. You should now see following output in the server console:
+
[source,options="nowrap"]
----
INFO  [stdout] (http-/127.0.0.1:8080-1) Parsing the document using the SAXXMLParser!
