Question

通过Jetty（8.1.8.v20121106），我已经无缘无故地尝试通过JNDI使用HSQLDB公开数据源两整天。大多数教程都已过时：例如http://dinukaroshan.blogspot.com/2012/04/setting-up-jndi-with-jetty-embedded.html使用Jetty 6，这从使用的包名称（Mortbay而不是eclipse）中显而易见，或者他们只关注jetty.xml和jetty-env.xml文件，没有提供任何Java代码示例，他们如何使用这样的配置文件： http://wiki.eclipse.org/Jetty/Feature/JNDI#Example_Webapps

我做这件事的最佳尝试给了我以下结果：

我的jetty.xml文件如下：

<?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>

我将以下内容添加到web.xml（这恰好是一个axis2 Web应用程序）：

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

这是我用来使用Jetty配置的Java代码：

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);


    }

我做错了什么？是否有最新的教程可以让我使用HSQLDB作为我的DBMS，JNDI来公开数据源和Jetty8？

非常感谢你的帮助。

这不是一个完整的答案，但在您提供的第二个wiki链接中显而易见的是使用DataSource。创建了一个javax.sql.DataSource实例。 HSQLDB的设置是这样的，当在给定示例中使用它而不是Derby时：

<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>

Jetty 8（嵌入式）与HSQLDB数据源
