请求者无法建立连接。Jetty、Lift/Scala、iSeries DB2/400

我正在阅读Gilberto T.Garcia Jr的Lift应用程序开发食谱，遇到了一个我似乎无法解决的问题。我已经复制了源代码Chap06映射表，并试图对其进行修改，以使用我的IBMi（iSeries，AS/400，i5）数据库。我能够使它与第一种类型的连接使用Squeryl记录工作。然而，我似乎不知道如何使用JNDI数据源实现这一点。我花了几天的时间在互联网上搜索设置这个的例子，但没有找到一个涉及DB/400数据库连接的好例子。下面是我在尝试启动容器和为使其正常工作而修改的代码时遇到的错误。任何帮助都将不胜感激。 对于来自jt4oo.jar（jtOpen）的数据源类，似乎有一些选择，我不确定哪一个是最好的，或者可能还有其他选择。我一直在尝试这三种方法，并假设第一种方法是正确的

com.ibm.as400.access.AS400JDBCManagedConnectionPoolDataSource
com.ibm.as400.access.AS400JDBCConnectionPoolDataSource
com.ibm.as400.access.AS400JDBCDataSource

谢谢。鲍勃

这是错误的开始：

jdbc/dsliftbook

[用户]
[密码]

好的，我已经设法接通了。一个问题是jetty env xml文件中的引号。而且我使用的用户名/密码显然没有实现这一点所需的权限，我不确定为什么，因为这是我在所有iSeries开发中使用的相同id/密码。所以现在，我是另一个拥有安全官员权限的用户配置文件，直到我知道发生了什么或者需要什么权限

登录后，我无法为用户设置库列表，这导致SQL失败。它正在寻找一个与用户ID相同的库名称。目前，我通过创建一个与用户ID相同的库来解决这个问题

这里的另一个问题是，尽管我同时提供了ID和密码，但在连接之前，系统会提示我输入ID/密码。ID和url已填写，但密码始终必须重新键入

我已经包含了jetty env xml文件和boot.scala文件的当前源代码。希望这能帮助其他人

感谢戴夫和詹姆斯的帮助

您从JDBC驱动程序收到一个SQLException，告诉您它无法连接到数据库。检查您的URL、用户名和密码是否正确。如果它们看起来正确，请尝试在不使用java的情况下从运行应用程序的机器连接到服务器，看看是否成功。您还可以在db日志中找到有关db拒绝连接原因的更多信息。您的数据库uri上的引号似乎放错了：

“jdbc:as400://www.[server].com；libraries=PLAY2TEST”；命名=系统；错误=完整

应该是

“jdbc:as400://www.[server].com；libraries=PLAY2TEST；naming=system；errors=full；”

我已经修复了引号，实际上已经完全删除了它们。还是不行。对于非数据源连接，以下操作有效

import org.squeryl.Session import org.squeryl.adapters.DB2Adapter import net.liftweb.squeryrecord.squeryrecord Class.forName（“com.ibm.as400.access.AS400JDBCDriver”）def connection=DriverManager.getConnection（“jdbc:as400://www.{server.com/；naming=1；libraries=PLAY2TEST；”、“[用户]、“[密码]”）squeryrecord.initWithSquerylSession（Session.create（connection，new DB2Adapter））

我也能够以QUSER身份登录。我的个人资料似乎有一些不同之处，使我无法使用它登录。
