Question

我使用xsbt v.0.10.1，网页插件，电梯v2.4-M4，Scala 2.9.1，Jetty 8.0.0.v20110901。

在Boot.scala中我添加了这样的代码：

DefaultConnectionIdentifier.jndiName = "jdbc/db"
logger.warn("JNDI connection availbale ? " + DB.jndiJdbcConnAvailable_?)

在码头日志中，我看到：

08:39:06.562 [Scanner-0] WARN  bootstrap.liftweb.Boot - JNDI connection availbale ? false

我使用web.xml v2.5：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>

我的应用程序的context.xml：

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

<!-- ==================================================================

Note. If this file did not exist or used a context path other that /test
then the default configuration of jetty.xml would discover the test
webapplication with a WebAppDeployer.  By specifying a context in this
directory, additional configuration may be specified and hot deployments 
detected.

我尝试使用检查JNDI可用性的简单java应用程序并且它有效，似乎在sbt中存在问题。

也许某人已经有这样的问题？

感谢。

这是Lift v2.4-M4

的错误

这是在Boot.scala的开头：

DefaultConnectionIdentifier.jndiName = "jdbc/db"
logger.warn("JNDI connection available (manyally) ? " + (((new InitialContext).lookup("java:/comp/env/jdbc/db").asInstanceOf[DataSource]) != null))
logger.warn("JNDI connection available (lift) ? " + DB.jndiJdbcConnAvailable_?)

打印：

16:43:52.937 [main] WARN  bootstrap.liftweb.Boot - JNDI connection available (manyally) ? true
16:43:53.015 [main] WARN  bootstrap.liftweb.Boot - JNDI connection available (lift) ? false

作为临时解决方法，我实现了ConnectionManager并添加到DB.defineConnectionManager。

Eclipse Jetty v8.0 JNDI DataSource在scala lift应用程序中不可用
