我需要使用C3p0连接池为H2数据库实现Jetty 9.0.3 Web服务器的JNDI,我在HETTY-HOME目录的lib / ext中放置了H2和C3p0 jar,我创建了一个jetty-env我的WEB-INF中的.xml文件。

WEB-INF /码头-env.xml

 <?xml version="1.0"?>
    <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
    <Configure class="org.eclipse.jetty.webapp.WebAppContext">
        <New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource">
            <Arg>jdbc/testDS</Arg>
            <Arg>
           <New class="com.mchange.v2.c3p0.ComboPooledDataSource">
           <Set name="driverClass">org.h2.Driver</Set>
           <Set name="jdbcUrl">jdbc:h2:/C:/data/test</Set>
           <Set name="user">sa</Set>
           <Set name="password"></Set>
                </New>
            </Arg>
        </New>
    </Configure>

我正在实现启用了plus配置的嵌入式jetty,通过以下类的main方法创建一个Jetty服务器实例:

WebServer.java

import java.io.File;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.util.resource.ResourceCollection;
import org.eclipse.jetty.webapp.WebAppContext;

public class WebServer
{

    public static void main(String[] args)
    {
        // Creating Jetty Server on port 8080
        Server webServer = new Server(8080);
        org.eclipse.jetty.webapp.Configuration.ClassList classlist = org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(webServer);
        classlist.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration", "org.eclipse.jetty.plus.webapp.EnvConfiguration",
                "org.eclipse.jetty.plus.webapp.PlusConfiguration");
        WebAppContext wac = new WebAppContext();
        // Set WAR Path to WebAppcontext from disk
        File warPath = new File("C:/Users/XXXX/src/com/UI");
        wac.setWar(warPath.getAbsolutePath());
        wac.setContextPath("/");
        wac.setBaseResource(new ResourceCollection(new String[] { "./WebContent", "build/classes" }));
        webServer.setHandler(wac);
        try
        {
            InitialContext ic = new InitialContext();
                DataSource myDS = (DataSource)ic.lookup("java:comp/env/jdbc/testDS");     
            System.out.println("param ::: "+myDS);
            webServer.start();
            webServer.join();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

    }

}

我收到以下错误,我该如何解决?

javax.naming.NameNotFoundException; remaining name 'env/jdbc/testDS'
    at org.eclipse.jetty.jndi.NamingContext.lookup(NamingContext.java:505)
    at org.eclipse.jetty.jndi.NamingContext.lookup(NamingContext.java:536)

2 个答案:

答案 0 :(得分:3)

您是否尝试更改字符串&#34; java:comp / env / jdbc / testDS&#34;只是&#34; jdbc / testDS&#34;?我认为这是一个跳船9&#39;功能&#39;。

答案 1 :(得分:1)

我有同样的问题。我使用了<Arg>java:comp/env/jdbc/testdb</Arg>代替<Arg>jdbc/testdb</Arg>而且它有效

<New id="JndiResource" class="org.eclipse.jetty.plus.jndi.Resource">
 <Arg></Arg>
 <Arg>java:comp/env/jdbc/testdb</Arg>
 <Arg>
  <New class="com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource">
   <Set name="Url">jdbc:mysql://127.0.0.1:3306/mydb</Set>
   <Set name="User">user</Set>
   <Set name="Password"></Set>
  </New>
 </Arg>
</New>

当然在我的查询中我使用了java:comp/env/jdbc/bratedb
