Jetty 8(Embedded) With HSQLDB Datasource

Question

I've been hopelessly trying for two complete days to expose a data source using HSQLDB through JNDI, through Jetty (8.1.8.v20121106). Most of the tutorials out there are out of date: For example http://dinukaroshan.blogspot.com/2012/04/setting-up-jndi-with-jetty-embedded.html uses Jetty 6, which is obvious from the package names that are used (Mortbay instead of eclipse), or they just concentrate on the jetty.xml and jetty-env.xml files, without giving any Java code samples on how did they consume the configuration files like this one: http://wiki.eclipse.org/Jetty/Feature/JNDI#Example_Webapps

My best attempt at doing it has given me the following result:

My jetty.xml file is as follows:

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">

<Configure id='wac' class="org.eclipse.jetty.server.Server">

  <!-- ==============================================================  -->
  <!-- Add the DataSource(s) only valid for this webapp below          -->
  <!-- ==============================================================  -->

  <New id="MySqlDS" class="org.eclipse.jetty.plus.jndi.Resource"> 
    <Arg>jdbc/MySqlDS</Arg>
    <Arg>
        <Set name="driverClass">org.hsqldb.jdbcDriver</Set>
        <!--<Set name="url">jdbc:hsqldb:sample</Set>-->
        <Set name="user">sa</Set>
        <Set name="password"></Set>
    </Arg>
  </New>

</Configure>

I added the following to my web.xml (This happens to be an axis2 web application):

  <resource-ref>
    <res-ref-name>jdbc/MySqlDS</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
  </resource-ref>

And this is the Java code I'm using to consume the Jetty configuration:

public ServerManager(int webServerPort,String jettyConfigurationsFilePath, String webApplicationPath) throws Exception
    {
        System.out.println("Initializing server");
        this.webServerPort = webServerPort;
        this.webApplicationPath = webApplicationPath;

        server = new Server(webServerPort);
        XmlConfiguration configuration = new XmlConfiguration(new File(jettyConfigurationsFilePath).toURI().toURL());
        configuration.configure(server);
        System.out.println("Finished configuring Jetty Server...");

        System.out.println("Server initialized");
        System.out.println("Server state is now " + server.getState());
        WebAppContext webapp = new WebAppContext();
        webapp.setContextPath("/");
        webapp.setWar(webApplicationPath);
        server.setHandler(webapp);


    }

What am I doing wrong? Is there an up-to-date tutorial that would allow me to use HSQLDB as my DBMS, JNDI to expose the data source, and Jetty8?

Thanks a lot for the help.

This is not a complete answer, but something obvious in the second wiki link you provide is the use of a DataSource. An instance of javax.sql.DataSource is created. The settings for HSQLDB are like this, when it is used instead of Derby in the given example:

<Configure id='wac' class="org.eclipse.jetty.webapp.WebAppContext">
...
<New id="myds" class="org.eclipse.jetty.plus.jndi.Resource">
  <Arg><Ref id="wac"/></Arg>
  <Arg>jdbc/mydatasource</Arg>
  <Arg>
    <New class="org.hsqldb.jdbc.JDBCDataSource">
      <Set name="DatabaseName">file:mytestdb</Set>
      <Set name="User">SA</Set>
      <Set name="Password"></Set>
    </New>
  </Arg>
</New>
</Configure>
