Jetty 7: configuring JNDI for Start.java

问题:

Following Wicket 1.5's lead, I'm converting a project from Jetty 6.1.25 to 7.5.0.v20110901. My existing Start.java contains the following setup, which I use to configure JNDI:

    EnvConfiguration envConfiguration = new EnvConfiguration();
    URL url = new File("src/main/webapp/WEB-INF/jetty-env.xml").toURI().toURL();
    envConfiguration.setJettyEnvXml(url);

    bb.setConfigurations(new Configuration[]{new WebInfConfiguration(),
                         envConfiguration,
                         new org.mortbay.jetty.plus.webapp.Configuration(), new JettyWebXmlConfiguration(),
                         new TagLibConfiguration()});

Then my jetty-env.xml has the following:

<Configure class="org.mortbay.jetty.webapp.WebAppContext">

    <New class="org.mortbay.jetty.plus.naming.Resource">
        <Arg>jdbc/myapp</Arg>
        <Arg>
            <New class="org.springframework.jdbc.datasource.DriverManagerDataSource">
                <Set name="driverClassName">com.mysql.jdbc.Driver</Set>
                <Set name="url">jdbc:mysql://localhost/myapp?characterEncoding=utf8</Set>
                <Set name="username">username</Set>
                <Set name="password">password</Set>
            </New>
        </Arg>
    </New>

</Configure>

This has worked great in Jetty 6, but in 7, org.mortbay.jetty.plus.webapp.Configuration does not seem to exist (or perhaps I'm missing a Jar).

Can someone give me some guidance on how to configure JNDI with Jetty 7?

Put the following into src/test/jetty/jetty-env.xml:

<Configure id="wac" class="org.eclipse.jetty.webapp.WebAppContext">
    <New class="org.eclipse.jetty.plus.jndi.EnvEntry">
    <Arg>jdbc/mydatasource</Arg>
    <Arg>
        <New class="com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource">
            <Set name="Url">jdbc:mysql://localhost/mydatabase?characterEncoding=utf8</Set>
            <Set name="User">username</Set>
            <Set name="Password">password</Set>
        </New>
    </Arg>
    </New>
</Configure>

Then modify Start.java to define the following properties:

System.setProperty("java.naming.factory.url.pkgs", "org.eclipse.jetty.jndi");
System.setProperty("java.naming.factory.initial", "org.eclipse.jetty.jndi.InitialContextFactory");

And add the following configuration to the WebAppContext:

EnvConfiguration envConfiguration = new EnvConfiguration();
URL url = new File("src/test/jetty/jetty-env.xml").toURI().toURL();
envConfiguration.setJettyEnvXml(url);

bb.setConfigurations(new Configuration[]{ new WebInfConfiguration(), envConfiguration, new WebXmlConfiguration() });

Starting with Jetty 7, the package name was changed from org.mortbay.jetty to org.eclipse.jetty.

In addition, org.eclipse.jetty.plus.webapp.Configuration was renamed in version 7.2.0 and the new name is PlusConfiguration. I'm guessing this was done to avoid a name clash with org.eclipse.jetty.webapp.Configuration.
