LiftのORMをmainメソッドから使う方法

WEBアプリを起動しないで、LiftのORMを使いたい場合には、ORMのメソッドを使う前にBoot.bootを実行しておけば使えるようになる。

サンプル

  import bootstrap.liftweb._

  def main(args: Array[String]) = {
    val boot = new Boot
    boot.boot

bootしない場合のエラー内容

Exception in thread "main" java.lang.NullPointerException: Looking for Connection Identifier DefaultConnectionIdentifier but failed to find either a JNDI data source with the name lift or a lift connection manager with the correct name
